A. CROSNIER, B. RICHER DE FORGES & P. BOUCHET
In the 1980s, new opportunities for collaborative oceanographic research in partnership with Indonesian scientists
were formalised through a joint agreement between the Indonesian and French governments. A series of three research
vessels, "Banina Jaya" 1, 2 and 3 were built in France and became operational in Indonesia in 1990-91. As we submitted
to the ad hoc committee a proposal for deep-sea biological exploration, our suggestion to target the Kai Islands met the
approval of the Indonesian government, which insisted that the seas of Eastern Indonesia had to receive special
attention. The Karubar (a contraction of the names of the Kai, Aru and Tanimbar Islands) project was thus bom.
The purpose of the expedition was to:
(a) document the composition of the deep-sea fauna and
(b) investigate potential economic resources in the untapped deep-sea benthos, with special emphasis on shrimps.
This dual goal was reflected in the composition of the scientific staff, which included zoologists as well as fisheries
biologists from several Indonesian and French institutions: Pusat Penelitian dan Pengembangan Oseanologi LIP1 (P30
LIPI) [Institute of Oceanology of the Indonesian Academy of Sciences], Balai Penelitian Perikanan Laut
(BALITKANLAUT) [Indonesian Institute of Fisheries], Badan Pengkajian dan Penerapan Teknologi (BPPT) [Indonesian
Ministry of Science and Technology], the Institut Fran^ais de Recherche Scientifique pour le Ddveloppement en
Cooperation (ORSTOM) [French Institute of scientific Research for Development through Cooperation], and the Musdum
National d'Histoire Naturelle (MNHN) [French National Museum of Natural History]. A total of 15 Indonesian and 7
French staff took part in the expedition, with Dr K. Moosa (P30 LIPI) as senior scientist and Lt. Col. Handoko the
commanding captain (see Appendix 1 for composition of staff).
The expedition was initially planned to depart from Ambon on October 7, 1991 and last 27 days. However, a series of
incidents, partly technical, delayed departure until October 21 and, as a result, only 13 days of work were available. Hence
our initial programme could not be carried out in full and we had to cancel the transects near the Aru Islands. A total of
91 stations, of which 85 were successful, were carried out near the Kai and Tanimbar Islands, at depths between 200 and
1200 m: 18 dredge hauls and 19 trawls near Kai. 10 dredges and 44 trawls near Tanimbar (List of stations: Appendix 2).
Incidentally, this is exactly the same number of hauls carried out by the "Siboga" expedition at depths below 200 m,
which points to the importance of the Karubar expedition, despite its short duration. It should be noted, however, that
the "Siboga" sampled many more stations in very deep water: 30 "Siboga" stations are deeper than 1000 m. versus only
5 Karubar stations at such depths.
The 13 papers included in the present volume provide much new information about Cnidaria (Scleractinia), Mollusca
(Bivalvia, Gastropoda and Cephalopoda), Crustacea (Decapoda) and Echinodermata (Crinoidea). In addition, over
20 papers published elsewhere are based wholly or in part on the zoological collections made during Karubar (List of
publications: Appendix 3). Undoubtedly, they are many more to come, which will document and describe the still little-
known fauna of the Indonesian archipelago. From a zoological point of view. Karubar can therefore be considered to
have been very successful, and we may only wish for further such cruises and volumes of expedition reports.
From the point of view of fisheries, however, the results of the Karubar expedition have been somewhat
disappointing. Considering the general geomorphology of the region, we did not expect vast trawlable bottoms near the
Kai islands, but the bathyal slope East of the Tanimbars appeared much more promising, especially in the context of
commercial fisheries off the Australian northwest shelf. Indeed, we encountered extensive flat areas suited for commercial
trawling. However, populations of echinoderms (holothurians, echinoids and ophiuroids) are so abundant that they
constitute the main catch. Furthermore, the very soft muddy bottoms and strong currents do not facilitate trawling
operations. We did encounter a number of potentially valuable commercial species of crustaceans (peneids: Aristeus,
Penaeopsis, Haliporoides, Metapenaeopsis, Hymenopenaeus, Hadropenaeus', and pandalids: Heterocarpus, Plesionika),
but they are apparently never abundant. One exception might be species of Metanephrops at depths between 250 and
300 m, but our initial results need to be confirmed by commercial deep-sea trawlers.
As noted above, Mortensen (1923) had suggested that the Kai Islands would be "an ideal place” for a tropical marine
laboratory, because of the “rich and varied fauna of genuine abyssal forms [occuring] over the whole of the large plateau
of 2-400 m depth". Are the results of the Karubar expedition in line with Mortensen's enthusiasm? At this stage, only
part of the zoological material has been studied and the results are rather contrasting. For instance, Cairns & Zibrowius
(this volume) report the highest regional diversity of azooxanthellate Scleractinia: 125 species were collected near the
Kai Islands versus 69 species, for example, near Lubang Island, Philippines, which has been intensively sampled during
the Musorstom 1, 2 and 3 expeditions. Also, considering the difference in sampling effort, the diversity in species of
Pectinoidea (Mollusca, Bivalvia) appears greater in the Arafura Sea than in New Caledonia (DlJKSTRA, this volume).
Conversely, several nominal species of pentacrinid crinoids previously recorded from the area are now shown to be
ecophenotypes and the pentacrinid crinoid fauna consequently appears less diverse than that recorded elsewhere in
Indonesia (Am£ziane, this volume). Probably such contrasting patterns of species richness in different zoological groups
only reflect preferences for different bottom types.
The occurrence of stalked crinoids in comparatively shallow water, which had so much impressed Mortensen, is
confirmed by the Karubar expedition, with the shallowest record of Saracrinus at 290 m (245 m by Mortensen). This is
admittedly very shallow by temperate North Atlantic standards, but is not exceptional in tropical waters. For instance,
pentacrinids occur from 290 m and deeper in New Caledonia (Bourseau et al., 1991) and from 185 m and deeper in the

Philippines (Bourseau & Roux, 1989). In fact, we suspect that the Kai Islands appeared so exceptional to Mortensen
because, despite being a much-travelled marine biologist, he had only limited experience of tropical deep-sea faunal
assemblages. In the eyes of a European zoologist, stalked crinoids were abyssal animals and their occurence in shallow
waters called for a special explanation. Instead, we suggest that the occurrence of stalked crinoids, as well as other
markers of the deep-sea fauna, such as elasipods and echinothurids, in the 200-500 m depth interval is the norm at
tropical latitudes in the Indo-Pacific. The pectinoid bivalves provide limited evidence that the shallowest occurrence of
certain species is shallower in the Arafura Sea than in New Caledonia, through the opposite is true for other species. In
conclusion, based on the evidence available and our own field experience in other tropical Indo-Pacific regions we regard
the Kai Islands as a rich, but not exceptional, place.
La campagne Karubar, appellation provenant d'une contraction des noms des lies Kai, Aru et Tanimbar,
toutes situees en mers de Banda et d'Arafura dans lesquelles s'est effectuee la campagne, a ete progranmiee dans le
cadre de la cooperation franco-indonesienne en oceanographie et cofinancee par les deux parties.
Les objectifs principaux de cette campagne etaient l'etude de la faune bathyale et une premiere estimation des
ressources de la pente continentale en crevettes et poissons commercialisables, dans Test de l'lndonesie.
La campagne, prevue pour 27 jours, s'est faite sur le navire indonesien de recherches "Banina Jaya /",
magmltque unite construite en France par la CMN, de 60 m de longueur, jaugeant 700 tx. et dont c'etait la
premiere campagne de recherche en biologie.
Le navire pouvant embarquer, sans difficult^, une vingtaine de scientifiques, l’equipe indonesienne etait
nombreuse et regroupait quatre chercheurs du BBPT (Badan Pengkajian dan Penerapan Teknologi) que Ton peut
assimiler a noire Ministere de la Recherche et de la Technologie, six du BALITKANLAUT (Balai Penelitian
Perikanan Laut) qui correspond a notre ancien Office des Peches et cinq du P30 LIPI (Pusat Penelitian dan
Pengembangan Oseanologi LIPI) qui est 1'Institut d'Oceanologie dependant de 1'Academie des Sciences
indonesienne, plus un de la Direction des Peches.

Du cotd fran^ais, on trouvait trois chercheurs de l'ORSTOM et trois chercheurs du Museum national d'Histoire
naturelle, a Paris, plus un maitre d'equipage de l'ORSTOM venu mettre son savoir-faire a la disposition de
l'equipage indondsien pour le greement et la manoeuvre des engins de peches (dragues, chaluts h perche et chalut a
panneaux). La presence de ce dernier devait se reveler d'autant plus utile que l'equipage du navire etait exclusivement
compose de militaires, le navire etant arme par la Marine nationale indonesienne.

DEROULEMENT DE LA CAMPAGNE
A I origine le Baruna Jaya 1 " devait appareiller de Jakarta le 2 octobre et rejoindre Ambon en cinq jours de mer.
La mission scientifique devait embarquer alors et la campagne debuter le 7 octobre.
Mais ll n en a pas ete ainsi a la suite de toute une serie de contre-temps : defaillance d'un transitaire livrant le
materiel envoye de France avec 19 jours de retard, lenteurs administratives pour I'obtention du visa de travail du
maitre d equipage venu de Nouvelle-Caledonie, petits problemes materiels divers avec les engins du bord (poulie
compteuse, treuil, sondeurs) ont retardd l'appareillage de Jakarta jusqu'au 12 octobre. II etait alors decide que deux
des chercheurs fran?ais et le maitre d'equipage feraient la traversee Jakarta- Ambon a bord du " Baruna Jaya I" afin
d assurer la mise en place de tout le materiel durant la traversee.
Le 17 octobre, le "Baruna Jaya 1 " arrivait a Ambon et I'equipe embarquee etait complete le 19 octobre au
matin, avec I amvee du chef de I'equipe indonesienne. L'appareillage etait alors prevu pour le soir meme a 17h00.
CAMPAGNE KARUBAR

Cependant des problemes d’avitaillement cn eau et en vivres, ainsi qu'une aimable invitation du Commandant de
la Marine a Ambon, le 19 au soir, obligeaient de remettre a nouveau l'appareillage qui, ne pouvant avoir lieu un
dimanche, etait alors fixe au 21 et a 7h00 du matin, les appareillages de nuit etant interdits.
Finalement cet appareillage, un peu laborieux, avait bien lieu h cette date et a cette heure.
Lors de 1 etablissement du programme de campagne 27 jours de mer avaient ete prdvus, mais une fois en mer, le
Commandant nous prevenait que le navire ne pouvait rester plus de 14 jours en mer, car au dete l'eau douce
viendrait a manquer. Si Ton enlevait les 3 jours de mer necessaires aux transits, la duree de travail utile se trouvait
ramende h 1 1 jours, ce qui etait loin du programme etabli. Finalement un rationnement de l'eau etant accepte, la
duree de la sortie etait portee a 19 jours, ce qui permettait d'avoir 16 jours de travail en mer.
En fait cette duree a, par la suite, etd ramenee h 13 jours, un message de I'Amiraute indonesienne ayant demande
au Commandant de se derouter, lors du retour, sur Timor pour y recuperer un engin suspect trouvd en mer (qui s'est
revele etre un courantometre enregistreur).
Durant ces 13 jours, nous avons bendficie d'une mer pratiquement toujours calme, ce qui a considerablement
facilite les operations de dragages et de chalutages, qui etaient nouvelles pour l'equipage.
Plusieurs types d’engins ont dte utilises :
— drague Waren,
— drague epibenthique,

Le 22 octobre a 8h00, ayant bendficie de courants favorables et la machine ayant ete un peu poussee, lc "Baruna
Java I" parvenail aux lies Kai, au sud de I'ile Taam, et nous effectuions le premier dragage, cntre 156 et 305 m, au
voisinage des stations 192 du "Challenger" et 46 de l'expedition danoise aux ties Kai, faite en 1922 et dirigee par le
Professeur MORTENSEN. Ces stations ont ete signalees comme ayant permis des recoltes zoologiques
particulierement riches. En fait, le fond compose de sable detritique grassier avec des debris de coraux et de
nombreux articles d 'Halimeda, nous fournissait une faune intdressante mais pas aussi riche que celle recoltee par le
"Challenger" et MORTENSEN.
Fig. 4. — Bernard M£tivier gree une drague Waren.
On peut d'ailleurs mentionner ici que nos rdcoltes n'ont que tres rarement correspondu h cclles indiquees par
MORTENSEN. En particulier dans des zones signalees comme riches par MORTENSEN, il nous a souvent ete
impossible de mettte un engin a l'eau, compte tcnu de la nature tourmentee des fonds. Ceci est-il du a des
positionnements peu exacts ?
La journee du 22 octobre etait consacree a une serie de sept dragages et chalutages a perche dans cette zone. Les
fonds s'y revelaient assez rugueux mais possibles a travailler, encore que les traits de chalut a perche n'aient guere
pu exceder 15 minutes.
Durant la nuit, nous empruntions le chenal separant les lies Tayandu des Petites Kai qui se montrait tres
accidente et reconnaissions, au sondeur, la zone situee au nord de ce chenal. Une cuvette chalutable de 10 milles sur
10 milles, a des profondeurs variant de 300 a 400 metres, y etait reperee; elle est toutefois parcourue, vers
132°35'E, par une faille nord-sud dont la profondeur atteint 80 m et qui doit done etre evitee.
La journee du 23 octobre etait consacree a l'exploration de cette cuvette. Le chalutagc s'y revelait facile (nous
avons pu y effectuer un trait de chalut k panneaux d'une heure sans probleme). Les recoltes y ont ete diversifies
mais si, en particulier, de nombreux crustaces commercialisables : langoustines ( Metanephrops ), crevettes peneides
( Penaeopsis , Haliporoides, Metapenaeopsis, Hymenopenaeus , Hadropenaeus), Pandalidae ( Heterocarpus ,
Plesionika) y etaient bien representees, aucune espece n'a ete trouvee en abondance.
Les 24 et 25 octobre, nous allions vers l'est et explorions la zone se trouvant au nord du chenal separant les
Petites Kai de la Grande Kai (6 dragages dont 1 epibenthique, 4 chalutages a perche, 1 chalutage a panneaux). Cette
zone se montre aisement dragable et chalutable par endroits et plus difficilement & d'autres. Parfois la presence

d'enormes buttes de vase, notamment vers 600 m, a provoque l'interruption du trait. Cette zone ne fournissait pas
d'indices plus encourageants que la precedente en ce qui conceme les especes commercialisables; bien entendu.
comme elle s’etend a des profondeurs superieures a la precedente, les grosses crevettes peneides ( Aristeus ) y sont
presentes, de meme que l’enorme langoustine Metanephrops neptunus, mais pas, d'apres ce que nous avons pu voir,
en quantites commerciales.
Le 26 octobre, nous explorions le grand
chenal scparant les Petites Kai de la Grande Kai
(6 dragages, 3 chalutages a perche), dont la
profondeur, dans sa partie la plus resserree,
n'excede pas 400 m. Les fonds, couverts d’une
vase gluante avec souvent des affleurements
rocheux, se montrerent peu interessants. Par
ailleurs de forts courants, variables, rendirent les
manoeuvres difficiles ne nous incitant pas a
perseverer dans cette zone. Lors de cette journee,
la drague, crochee, ne put etre recuperee qu'apres
plus d'une heure d'efforts.
La journee du 27 octobre etait consacree a
une serie de 5 chalutages a perche dans le sud des
ties Kai, sur des fonds souvent assez accidentes
et peu faciles a travailler, mais aussi, parfois,
reguliers. C'est ainsi que les chalutages CP 35
et CP 36 ont pu durer une heure chacun, a des
profondeurs variant entre 390 et 500 m pour le
premier et 210 a 270 m pour le second,
permettant d'cxcellentes et abondantes captures.
De meme que dans le chenal, de forts courants
ont, dans cette zone, perturbe les operations.
Les journees passant, il etait alors decide de
rallier les Ties Tanimbar, seconde zone dont
l'expioration nous avait ete assignee. Ce transit
etait effectue dans la nuit du 27 au 28 octobre.
Trois radiales Etaient prevues dans la zone
s'etendant au sud-est de ces Ties.
Les fonds y different totalement de ceux
Fig. 5. Arrivee sur le pont d'une drague Warfen pleine de vase. rencontres aux Ties Kai. D'une maniere generate,
aux profondeurs explores (200 a 1550 m,
maximum de la profondeur dans cette zone) nous nous trouvions devant une pente douce et reguliere, avec toutefois
quelques variations notamment entre 850 et 1200 m ou la pente devient frequemmeent plus raide. Si les fonds
etaient durs aux profondeurs les plus faibles, ils etaient recouverts de vase a partir de 250-310 m. Cette vase, grise,
est souvent tres molle et rend les chalutages difficiles, d'autant que de forts courants (jusqu'a 2,7 nceuds) dont la
force se modifie rapidement, rendent difficiles le maintien du cap et surtout de la vitesse du navirc. Ces variations
de vitesse ont d'ailleurs provoque la perte de tout un train de chalutage, les panneaux s'etant enfouis dans la vase a
la suite d'une diminution trop importante de la vitesse.
Dix dragages, dont 3 epibenthiques, et 44 chalutages, dont 6 a panneaux, ont ete effectues dans cette zone.
Parmi les fonds les plus spectaculaires, on peut citer ceux a Virgularia (Pennatulacea) vers 290 m, ceux a
rachiopodes et scleractiniaires trouves entre 350 et 450 m essentiellement et ceux a echinodermes, tres nombreux
et diversifies. Vers 400-450 m, les holothuries, dont les molpadides et les elasipodes, etaient particulierement
abondantes, tandis que vers 800-1000 m on trouvait de tres nombreux oursins (Echinidae, Echinothuridae, Cidaridae
Spatangidae) et vers 1000 m des fonds a ophiures (Ophiuridae) et Hyalonoecia (Polychacta).

Les crinoides (. Saracrinus ), celebres dans la litterature par les recoltes du "Challenger aux lies Kai, retrouvtfs
dans ces memes ties par l'expedition KARUBAR jusqua 430 m de profondeur, n'ont ete trouves au large des .les
Tanimbar que jusqu'h 300 m de profondeur, ceci s'expliquant sans doute par la nature des fonds, une vase tres
molle, au dela de cette profondeur. • .
Dans toute la vaste plaine de vase ainsi exploree, de nombreuses especes de crustaces qui pourraient etre
commercialisms ont 6l6 recoltes, notamment plusieurs especes de langoustmes ( Metanephrops arafurensis ,
M. neptunus, M. sibogae, M. velutinus), mais aucune n'a malheuseusement 6t6 prise en quantile significative.
Le 5 novembre au soir le travail en mer se terminait, comme nous l'avons mentionne plus haut, plus tot que
prevu. Le 6 novembre le "Banina Jaja 1 " etait de retour a Ambon et les equ.pes scientifiques debarquaient.
RESULTATS
Quatre-vingt-onze chalutages et dragages, dont quatre-vingt-cinq ont dte reussis, ont ete faits entre 200 et
1200 m.
Du point de vue des peches commercials, les nSsultats sont ddcevants. S'il etait peu Evident de trouver des
zones chalutables suffisamment etendues aux Ties Kai, compte tenu de la geomorpholog.e de cette zone, on pouyait
esperer, par contre, que la pente bathyale prolongeant le plateau continental de l'lnan Jaya, & Test des lies
Tanimbar, serait prometteuse. Certes les zones chalutables y sont vastes, mais la presence d'une vase grise souvent
molle et gluante, l'existence de forts courants et la presence de tres importantes concentrations d echinodermes
(holothuries, oursins et ophiures) encombrant les fonds et colmatant les chaluts, ne sont pas faits pour rendre
rentable une peche industrielle. Des especes interessantes se trouvent sur ces fonds, mais ll semblerait que ce soit
toujours en quantite assez faible. Ce n'est que dans la partie sud de la zone prospectee que des apparences de
langoustines, peut-etre un peu plus encourageantes, ont ete observees sur les fonds de 250 it 300 m. Ceci dit, il ne
faut pas oublier les conditions dans lesquelles nous avons travaille et il est bien certain qu'une campagne faite par
un chalutier mene par des professionnels de la peche profonde, comme il en existe en Australie, serait maintenant
souhai table.

Si les resultats ont dtd decevants au plan du ddveloppement des peches, il n'en est pas de meme au plan de la
connaissance de la faune bathyale.
Avant nous plusieurs grandes expeditions ont travailld sur la faune d'eau profonde de l'lndonesie • celles du
"CMlenser (1872-1876), de la "Siboga" (1899-1900), de la "Galathea" (1950-1952), de Mortensen aux lies Ka“
(1922), sans oublier la campagne Corindon (1980) et l'expddition Snellius 2 en 1984 Beaucoup de ces
expddmons n'ont fan que traverser l'lndonesie, en y effectuant un nombre rdduit ^operations de peche. Quant i la
Siboga qui i est la plus connue en ce qui concerne 1'Indondsie, elle n'a effectud qu'un nombre de peches profondes
comparable k celui atteint par la campagne Karubar. Cette simple comparison situe bien rapport de la campagne
Karubar k notre connaissance de la faune bathyale indondsienne, encore qu'il faille la nuancer : si la "Siboga" n'a
pas fait, durant son people de pres de deux ans, plus de stations au del* de 200 m que nous en 13 jours elle a
effectud environ 30 stations h plus de 1000 m contre 5 seulement en ce qui concerne Karubar.
Le matdriel recoltd a dtd reparti de la manure suivante :
— la totahte des poissons ainsi, dans les dchinodermes, que la totality des astdries ont dtd conservdes par les
chercheurs mdondsiens.
— le reste du materiel a ete expedid pour tri et dtude au Musdum national d'Histoire naturelle, etant entendu
qu aprds etude une partie significative des rdcoltes serait renvoyde, identifiee, en Indonesie pour servir de collection
de rdference.

Les venues en France de chercheurs indondsiens pour participer aux tris et aux dtudes dtaient programmees. Au
moment ou nous dcnvons ces lignes, deux chercheurs sont ainsi venus, 1'un a deux reprises.

des campagnes MUSORSTOM 1, 2 et 3. De meme, si Ton considere les densites differen.es de recol.es, le nombre des
especes de Pect.no.dea (mollusques bivalves) parait plus grand en mer d'Arafura qu'en Nouvelle-Caledonie
(DlJKSTRA, dans ce volume). Par centre, .1 a ete montre (Ameziane dans ce volume) que plus.eurs especes de
crinoides pedoncules (pentaennes) signalees de la region de lies Kai n'etaient en fait que des ecophenotypes si bien
que la faune : de : ce groupe, autour des lies Km, apparait moins diversif.ee que dans d'autres regions de l'Indonesie II
est vraiscmblable que ces resultats son., en fait, largement en liaison avec la presence de fonds de nature plus ou
moms diversifiee. K
MoRT^r^ crinoides pedoncules dans des eaux relativemen. peu profondes, qui avait tellement impressionne
MORTENSEN, est confirmee par la campagne Karubar avec la recolte de Saracrinus a 290 m (245 m par
MORTENSEN). De telles profondeurs son. tres faibles si Ton se refere a ce que I'on observe dans l'A.Ian.ique Nord
mais n ont rien d exceptionnel en mers tropicales. Par exemple des pentacrines on. ete trouves a partir de 290 m en
Nouvelle-Caledonie (BOURSEAU « aL, 1991) et de 185 m aux Philippines (Bourseau & Roux, 1989) II est
vraisemblable que MORTENSEN s'etait si fortement en.housiasme pour les lies Kai parce que, malgre ses nombreux
voyages en tant que biologiste mar.n, il n'ava.t qu'une experience limitee de la faune d'eau profonde tropicale Aux
yeux d un zoolog, ste europeen, les crinoides pedoncules etaient des animaux abyssaux e. leur presence en'eaux
relativement peu profondes necessity une explication particuliere, alors que leur presence de meme que celle
d autres marqueurs de la faune d'eau profonde, tels que les elasipodes et les echinothurides, est la norme entre 200 e.
500 m dans I Indo-Pacilique tropical. Les mollusque bivalves Pectinoidea ne fournissent pas d'evidence nette •
certaines especes se trouvent & des profondeurs moindres en mer d'Arafura qu'en Nouvelle-Caledonie, mais e'est le
contraire qui est observe pour d'autres. En definitive, en se basant sur les resultats disponibles, et egalement sur
notre experience d autres regions tropicales de I'Indo-Pacifique, nous sommes amenes a considerer les ties Kai
comme une region riche mais non exceptionnelle.

ABSTRACT
A total ot 206 species of azooxanthellate Scleractinia are listed from the Philippine-Indonesian region, 176 of which
are reported as new records. The newly reported specimens originate primarily from the MUSORSTOM 1-3 and Karubar
expeditions, but also include specimens collected by the "Albatross", Danish Expedition to the Kei Islands, Snellius 2
Expedition, "Galathea", Mortensen's Java-South Africa Expedition, "Hakuho Maru", "Siboga", Corindon 2, and Estase 2
expeditions as well as some others. In all, approximately 15,600 specimens from some 640 stations are reported, the
new records including the description of 26 new species and 3 new genera. Also, 4 new combinations and 1 new name are
proposed ( Caryophyllia crosnieri for C. elongata Cairns, 1993, non Duncan, 1873).
The distribution and bathymetric ranges of the 206 species known from the combined Philippine-Indonesian region
are tabulated. 157 azooxanthellate species are now known from the Philippine Islands, with highest local diversities off
Lubang Island (69 species) and the Sulu Archipelago (66 species). 174 species are known from the Indonesian region, the
region with the highest diversity being the Banda Sea (138 species), specifically the Kai Islands (125 species). To a large
degree, these high levels of diversity reflect the intensity of sampling effort. 65 (or 31.5%) of the Philippine-Indonesian
species also occur in the Indian Ocean; 77 species (or 37%) off Japan; 67 species (or 32.5%) in the Australia and
New Zealand region; and 47 species (or 23%) among the other western Pacific Islands. Only 1 1 of these species (or 5.3%)
occur as tar east as continental eastern Pacific, and 1 1 also occur in the Atlantic Ocean. These corals occur from
0 to 2570 m, the deepest being Flabellum conuis. The highest diversity of species (123 species) has been found in the
200-400 m depth range.

The first example of sweeper tentacles in a deep-water coral is reported for Madrepora arbuscula. Examples of
commensal/symbiotic relationships are reported to occur with petrarcid ascothoracidan crustaceans (6 coral hosts),
acrothoracican cirripede crustaceans (4 coral hosts), eunicid polychaetes (4 coral hosts), and lumbrinerid polychaetes
(11 coral hosts). Several cases of epifauna living on live corals are the brachiopod Discradisca Stella and the gastropod
Malluvium sp. attached to Truncatoflabellum mortenseni, and a stalked suberitid sponge growing on Truncatoflabellum
paripavoninum.
RESUME
Cnidaria Anthozoa : Scleractiniaires sans zooxanthelles des Philippines et d'lndonesie.
206 espdces de scldractiniaires sans zooxanthelles sont recensdes dans la rdgion des Philippines et de I'lndondsie.
Pour 176 d'entre elles, des donndes nouvelles sont apportdes. Le matdriel etudie provient principalement des campagnes
Musorstom 1 d 3 (1976, 1980, 1985) aux Philippines et Karubar (1991) dans l'est de I'lndondsie. Diverses autres
collections sont dgalement prises en compte, dont notamment: "Challenger " (1874), "Siboga" (1899-1900),
"Albatross" (1908-1909), expedition danoise aux ties Kei (1922), expedition de Th. Mortensen it Java (1929),
"Galathea " (1951), "Hakuho-Maru " (1972, 1973, 1985), SNELLIUS 2 (1984), campagnes CORINDON 2 (1980) et Estase 2
(1984). Les dchantillons dtudies sont au nombre de 15.600 et proviennent d'environ 640 stations.
Trois genres nouveaux sont decrits {Confluphyllia, Ericiocyathus, Sympodangia) et 26 espdces nouvelles
( Balanophyllia crassiseptum, B. generatrix, B. serrata, Caryophyllia cornulum, C. karubartca, C. octonaria, C. secta,
C. unicristata, Confluphyllia juncta, Deltocyathus philippinensis, D. Stella, Endopachys bulbosa, Ericiocyathus
echinatus, Fungiacyathus fissidiscus, Madrepora minutiseptum, Rhizosmilia elata, Stephanocyathus regius,
Sympodangia albatrossi, Trochocyathus apertus, T. brevispina, T. discus, T. longispina, T. semperi, "Tropidocyathus"
labidus, Truncatoflabellum angustum, T. mortenseni). Un nom nouveau est introduit ( Caryophyllia crosnieri, nomen
novum) et 4 combinaisons nouvelles rdsultent de transferts dans un autre genre ( Colangia moseleyi, Premocyathus
dentiformis, Trochocyathus burchae, Deltocyathoides orientalis). Une espdce etrange, aux affinites incertaines ( incertae
sedis), est presentde, mais non decrite formellement.
Un tableau resume la repartition geographique et bathymetrique des 206 espdces recensdes dans la rdgion des
Philippines et de I'lndondsie. Aux Philippines (157 espdces), la diversitd est la plus dldvde autour de 1'ile Lubang
(69 espdces) et dans l'archipel de Sulu (66 espdces). En Indondsie (174 espdces), elle est la plus dldvde dans la mer de
Banda (138 espdces) et plus spdcialement aux ties Kai (125 espdces). Ces remarquables richesses en espdces refldtent aussi
une prospection particulidrement intense dans les secteurs en question. 65 des 206 espdces inventoriees dans la rdgion des
Philippines et de I'lndondsie vivent aussi dans l'ocdan Indien tropical, 77 au Japon, 67 autour de l'Australie ou au nord de
la Nouvelle-Zelande, et 47 autour d'autres iles du Pacifique occidental. Mais seulement 1 1 de ces espdces sont connues dans
le Pacifique oriental et 1 1 espdces dgalement dans l'ocdan Atlantique. La repartition en profondeur des espdces etudides
s'dtale entre 0 et 2700 m, Flabellum conuis etant l'espdce qui atteint la plus grande profondeur. L'intervalle de 200-400 m
est habitd par environ les 2/3 des espdces. Le genre Leptopenus, au squelette extremement fragile, a did reconnu pour la
premidre fois dans des fonds de 300 m seulement,
De nombreuses espdces prdsentent un mode de multiplication asexude: division transversale, fractionnement suivi de
rdgdndration, ddtachement de bourgeons. Pour la premidre fois des tentacules spdciaux, particulidrement allongds
("sweeper tentacles"), ont ete reconnus chez un scleractiniaire bathyal ( Madrepora arbuscula)', auparavant ce type de
tentacule dtait connu seulement chez divers scldractiniaires rdcifaux. Divers types dissociations symbiotiques plus ou
moins specialisdes ont ete reconnus. Les partenaires sont les suivants: crabes Cryptochiridae (avec Phyllangia
papuensis), crustacds ascothoracides causant des galles (dans Madrepora oculata, Balanophyllia carinata, Balanophyllia
sp., Deltocyathoides orientalis, Dendrophyllia sp. cf. D. ijimai, Flabellum lamellulosum)', cirripddes acrothoraciques
perforants (dans Balanophyllia crassiseptum, Balanophyllia sp., Javania lamprotichum, Tetliocyathus virgatus)',
polychdtes Eunicidae lids aux ddformations de colonies de Madrepora et de Neohelia, leurs tubes y dtant incorpores;
polychdte Lumbrineris flabellicola corrodant la surface du squelette (de Balanophyllia sp., Caryophyllia grayi,
C. spinicarens, C. spinigera, C. transversalis, Conotrochus brunneus, Flabellum lamellulosum, F. patens, Flabellum
sp., Rhizotrochus typus, Dendrophylliidae).
Des cas plus remarquables d'epifaune installee sur des coraux vivants, mais n’en ddpendant probablement pas, sont le
brachiopode Discradisca Stella et le gastropode Malluvium sp. sur Truncatoflabellum mortenseni, et un spongiaire
Suberitidae pddonculd sur Truncatoflabellum paripavoninum.

INTRODUCTION
This work may be considered as the concluding part 2 of the partial revision by Cairns (1989a) of the
azooxanthellate Scleractinia of the Philippines and adjacent waters. Whereas Cairns included only 58 Philippine
species from 5 families, this work lists 206 species in 1 1 families from the Philippine-Indonesian region,
including additional records of most species reported in Part 1. This work differs conceptually from Part 1
(CAIRNS, 1989a) in that it covers a larger geographic region, including most of Indonesia, and was based on a
much larger and varied collection.

COMBINED LIST OF STATIONS AND OF SPECIES OBTAINED PER STATION
This list provides the data of all stations mentioned in this report (ships, respectively cruises, in alphabetical
order) and of those stations of the "ALBATROSS" Philippines Expedition and of cruises MUSORSTOM 1, 2, 3
(Philippines) and CORINDON 2 (Indonesia) that were previously mentioned by CAIRNS (1989a). For some of the
stations previously mentioned by Cairns (1989a) the data are herein corrected.
The following abbreviations are used and placed after the species names:
CSD: (= confused station data) species found labeled as from this station, but certainly from another station
because of the unlikely depth;
C89: already reported by Cairns (1989a);
C89*: reported by Cairns (1989a), but under another name (see synonymy, remarks).

HISTORICAL REVIEW (INDONESIAN REGION)
Perhaps the earliest azooxanthellate corals reported from the Indonesian region were those collected by the
H. M. S. "Challenger" at stations 191-198 and 214, as reported by MOSELEY (1876, 1881). Sixteen species were
described, including 1 1 from one station (" Challenger " stn 192) at the Kai Islands at 256 m, 9 of those new
species. The Challenger specimens are deposited at the BMNH and were examined by both authors.

S. D. CAIRNS & H. ZIBROWIUS
The historically most significant collection of Indonesian deep-water corals, reported in at least 8 publications,
was that of the "Siboga" expedition of 1899-1900, which made 323 stations throughout the Indonesian region and
Sulu Archipelago (Weber, 1902; Tydeman, 1902). ALCOCK (1902a, b, July) published 2 preliminary accounts
in which he described 45 new species of deep-water corals from this expedition. Although the descriptions are
adequate, he did not include illustrations of these species or station numbers for the specimens. Just one month
later (ALCOCK, 1902c, August) his report on the deep-water ( i.e ., over 100 fathoms, 183 m) corals of the "Siboga
Expedition ("Siboga" Report 16a) appeared, in which he published verbatim the description of 37 of the 45 species
he described the previous month, 3 additional new species (Paracyathus pruinosus, Flabellum laciniatum var.
messum, and Pourtalosmilia dumosa ), 26 previously described species, and 7 lots identified only to the generic
level (a total of 73 azooxanthellate species). Illustrations and station data were included for all taxa in the "Siboga"
report, and, although ALCOCK (1902c: 2) noted that most of the new species had been published in a "preliminary
communication ... of the Journal of the Netherland Zoological Society", the 2 earlier publications were largely
forgotten until 1991 (HOEKSEMA & BEST, 1991). It is unknown why ALCOCK omitted 8 species from his Siboga
report that were included in his preliminary accounts. These species were shallow water (0-183 m)
azooxanthellates, on which he perhaps intended to write a separate "Siboga" report (ALCOCK, 1902c: 2);
nonetheless, 2 of these 8 species were later redescribed by van der HORST (1922) inadvertently as new species
using ALCOCK's original names: Dendrophyllia florulenta and Leptopsammia poculum (the latter described as
Endopsammia poculum by ALCOCK, 1902a). Even VAN DER HORST (1922) was apparently unaware of ALCOCK’s
preliminary papers. Only one of the other 6 species was ever cited; Flabellum weberi, a junior synonym of Javania
insignis was cited by CAIRNS (1989a, 1994), based on a collection label, not the ALCOCK publication. The
remaining 5 species: Trochocyathus weberi (= ? T. cooperi), T. cavatus, Endopachys weberi (= E. grayi),
Heteropsammia pisum , and Rhodopsammia (= Balanophyllia) corniculans , all described in Alcock (1902a), were
not subsequently reported. Aside from the 2 species redescribed by VAN DER HORST, the types of only 2 of the
other 6 species are now known to exist at the ZMA: Flabellum weberi and Endopachys weberi.
In a paper describing the shallow- water fungiids collected by the "Siboga", van der Horst (1921, "Siboga"
Report 16b) also reported 2 specimens of Bathyactis (= Fungiacyathus) palifera; and in a paper dedicated to the
study of Fungia patella, BOSCHMA (1923, "Siboga" Report 16d) also described a new Indonesian species,
Stephanophyllia neglecta, from a "Siboga " station off the Kai Islands. Another paper on "Siboga" azooxanthellates
(VAN DER Horst, 1922, "Siboga" Report 16c) was an account of the dendrophylliids of the expedition, which
included 36 species from Indonesian waters, 1 1 of these new; however, as mentioned above, 2 of these 1 1 new
species were previously described by ALCOCK (1902a). Most "Siboga" specimens are deposited at the ZMA (see
VAN SOEST, 1979 for type deposition) and have been examined by the authors.
Two more papers include reidentifications of "Siboga" specimens: ZIBROWIUS (1973) reidentified the "Siboga"
Dendrophyllia reported by ALCOCK (1902c) in the context of a revision of the genus Enallopsammia; and
ZIBROWIUS & Grygier (1985) reidentified two lots of Balanophyllia reported by VAN DER HORST (1922).
BEDOT (1907) reported Cyathelia axillaris from the Ceram Sea (depth unknown), a species previously reported
by Moseley (1881) from the adjacent Molucca Sea.
Azooxanthellate Scleractinia collected on the Danish Expedition to the Kai Islands (DEKI) in 1922 have been
reported in 3 publications. BOSCHMA (1923) listed 1 species, Stephanophyllia formosissima-, VAN DER HORST
(1926) reported 5 dendrophylliid species, including the new species Rhizopsammia nuda\ and BOSCHMA (1953)
reported Tubastraea aurea ( = T. coccinea and T. faulkneri) from the Kai Islands and Ambon. However, the bulk of
the specimens from that expedition are reported herein and are deposited at the NNM and ZMK (see Material).
More recent reports of Indonesian azooxanthellates from miscellaneous sources include: Polycyathus
furanaensis from Sulawesi (VERHEIJ & BEST, 1987); Anthemiphyllia dentata from the Banda Sea (BEST &
HOEKSEMA, 1987); Cryptotrochus javanus from the Java Sea (CAIRNS, 1988); and a revision of Heterocyathus and
Heteropsammia from the Indonesian region (HOEKSEMA & BEST, 1991).
A common theme in previous expedition reports has been a high diversity of deep-water species from the Kai
Islands, and the Indonesian region in general, as evidenced by the collections of the "Challenger", "Siboga", and the
Danish Expedition to the Kai Islands (Deki). This is confirmed herein on the basis of collections from the
SNELLIUS 2 and KARUBAR expeditions. ALCOCK (1902c: 3) alluded to the Kai Islands as second only to the Sulu

Archipelago in coral biodiversity; however, as a result of this study, 122 species are known from the Kai Islands,
and only 65 from the Sulu Archipelago.
Works containing references to fossil azooxanthellates from the Indonesian region include: Gerth (1921)
Miocene of Java; UMBGROVE (1938), Pleistocene of Talaud; Umbgrove (1950), Pleistocene of Java; and
Boekschoten et al. (1989), Pliocene-Pleistocene of Nias.
A review of previous records of azooxanthellate Scleractinia from the Philippines can be found in Cairns
(1989a).
MATERIAL
This study is based on the examination of approximately 15,600 coral specimens collected throughout the
Philippine-Indonesian region from some 640 stations. A specimen equates to an individual solitary corallum or a
colony or branch of a colonial species. Many of the new specimens were collected by the French and French-
Indonesian expeditions: MUSORSTOM cruises 1-3 (1976, 1980, 1986, respectively), which concentrated on
southwestern Luzon (vicinity of Lubang Island and Verde Island Passage), and also did some collecting near
southern Luzon (Mindoro and Panay) (FOREST, 1981, 1985, 1989); CORINDON 2 (1980), on the R.V. Coriolis,
which collected in Makassar Strait (Moosa, 1984); and Karubar (1991) on the R.V. Banina Jaya 1 , which made
extensive deep-water collections in the Banda Sea (Kai Islands) and Arafura Sea (southeast of Tanimbar Islands)
(CROSNIER, Richer de Forges & BOUCHET, 1997). Many of the MUSORSTOM 1 stations were made in a small
area north of Lubang Island near "Albatross" stn 5278 (the type locality of Neoglyphea inopinata), a "living fossil"
decapod crustacean. The French collections are divided among the MNHN, NMNH, and Puslitbang Oseanologi,
Jakarta. Many additional specimens from the Philippines and Banda Sea also came from the "Albatross" expedition
(1906-1909; see ANONYMOUS, 1910 for a history and station list of the expedition), and are deposited at the
NMNH. A remarkably large and diverse collection of azooxanthellates was also made available from the Danish
Expedition to the Kei Islands made in 1922 by Th. MORTENSEN and H. BOSCHMA. This expedition collected not
only near the Kai Islands but also in the Java Sea (MORTENSEN, 1923). Specimens are deposited primarily in the
NNM and to a lesser extent at the ZMK. Few specimens of shallow water azooxanthellates were found at the NNM
from the Snellius" expedition to Indonesia in 1930, but many upper slope specimens were available for study at
the NNM from the Snellius 2 (R/V Tyro) expedition of 1984, which made deep-water stations throughout the
Indonesian region (van DER Land & SUKARNO, 1986). Specimens from the following expeditions were also
examined. Galathea expedition (1950-1952), throughout the Philippine and Indonesian region (see Bruun, 1957;
WOLFF, 1964), deposited at the ZMK; Mortensen's Java-South African Expedition (1929-1930), primarily from the
Bali Strait, deposited at the ZMK; stations made by the "Hakuho Maru" (1972-1985) in the South China Sea,
Philippine, and Indonesian waters (see Nishiwaki, 1974; HORIKOSHI et al., 1983; HORIKOSHI & Ohta, 1987),’
deposited at the ORI and NMNH; and specimens from "Siboga" stations (1899-1900) in Indonesian waters that
were not previously reported (see Tydeman, 1902).
In addition to the newly reported specimens listed above, all previously reported specimens from the "Siboga"
xpedition (ALCOCK, 1902a-c; Horst, 1921, 1922; BOSCHMA, 1923) and specimens from the Indonesian and
Philippine stations of the "Challenger" Expedition (stations 191-213) were re-examined by the first author in 1994
an > the second author on various occasions. Semper's (1872) Philippine specimens were examined by the
second author.
Although not politically part of Indonesia or the Philippines, specimens from the eastern coast of Sabah,
alaysia (e.g., Darvel Bay, Celebes Sea) were included in this study, and their depth ranges included with those of
the Indonesian region.
METHODS
Species descriptions and illustrations are provided only for those species described as new or for those for which
equate cscription previously existed. Shorter diagnoses are provided for the remaining species for which new

of 176 (85%) of the 206 species known from the Philippine-Indonesian region, the remaining 30 species being
indicated in Table 1 by an asterisk but not discussed in the text. Most of these 30 are rarely collected species,
indeterminable species (e.g., those described but not illustrated by ALCOCK, 1902a, b), or probable junior
synonyms of species better known under other names (e.g., Balanophyllia dubia, B. ovalis, B. parallela). Although
some species of Heterocyathus and Heteropsammia occur in this region and are acknowledged to be
azooxanthellate, they are not included in this report.
Species synonymies are complete unless otherwise indicated with a reference to a more complete account;
however, it was attempted to include in the synonymies all references to specimens reported from the Philippine-
Indonesian region. When possible, all historical records were verified, but when material was unavailable and the
published account unclear, the synonymy entry and corresponding distribution record are queried.
In the "Material examined" sections, the number of specimens examined follows the station number, followed
by the museum of deposition, and its catalog number, if any. Holotypes and paratypes are deposited primarily at
the MNHN and NMNH, as well as Puslitbang Oseanologi - LIPI, Indonesia, in the case of Karubar material.
Essentially, only new material is reported in the Material Examined sections, not types or previously reported
specimens.
In order to avoid erroneous depth ranges for species as a result of bathymetrically wide-ranging trawls, a
confirmed depth range is employed in this paper, which is defined as the deepest shallow to the shallowest deep
component of all trawls considered. For example, if a species was trawled at a station indicating 20-300 m and
again at a station indicating 250-500 m, the confirmed depth range is 250-300 m, a depth range within which it
most likely was collected.
The SEM and most conventional photography was done by the first author, the former on a Cambridge
Stereoscan 100 in the SEM Laboratory of the NMNH.
COMMENSAL RELATIONSHIPS
Several types of specialized coral symbionts (other than simple epibionts) have been found associated with
various members of the species-rich fauna of the Philippines and Indonesia studied here.
Lumbrinerid polychaete eroding the coral skeleton. — This association has been described in detail
by ZIBROWIUS et al. (1975) on the basis of material from the northeastern Atlantic and the southwestern Indian
Ocean (South Africa), with additional records from Madagascar, the China Sea, and Japan. The coral-skeleton-
eroding polychaete Lumbrineris flabellicola (Fage, 1936) inhabits a soft tube exteriorly attached to the host, and
causes a superficial to deep erosion of the coral skeleton. The worm itself is easily lost by the mechanical con¬
straints of dredging and the subsequent manipulations, but frequently empty tube fragments remain attached to the
coral, or a corrosion trace can be detected on the coral even after the worm and tube have disappeared. This associa¬
tion occurs in the Philippines and Indonesia. Worms obtained during cruise MUSORSTOM 2 in the Philippines have
been compared by T. MlURA with Lumbrineris flabellicola from the northeastern Atlantic and Japan and have been
found to be the same species (L. flabellicola) in these widely distant areas (T. MlURA, in litt., 1989).
The following species have been found to be the coral partner of this association, specimens still bearing the
worm (WO), or still having empty tubes fragments attached (ET), or showing only a characteristic erosion trace
left over (TR):

Eunicid polychaete causing deformation of the coral colony. — Some colonies of Madrepora
oculata from Indonesia (" Albatross " stn 5645; Karubar stn 56) show deformations similar to those found in
colonies of Madrepora oculata , Lophelia pertusa , and Solenosmilia variabilis from the northeastern Atlantic, in
which the parchment-like tube of Eunice norvegica (Linnaeus, 1767) is overgrown by the coral coenosteum and
incorporated into the colony (Zibrowius, 1980). We have no information whether the deformations of Indonesian
M. oculata is caused by the same Eunice species. Similar deformations characterize all colonies of Madrepora
arbuscula and of Madrepora minutiseptum studied here. Even though no overgrown soft tube has been formally
identified in this material and no worm been extracted, it is presumed that the commensal organism is an eunicid
polychaete. Overgrown parchment-like Eunice tubes have also been found in some colonies of Neohelia sp.
cf. N. porcellana.
Acrothoracican cirripede crustacean boring the coral skeleton. — Acrothoracican cirripeds may
bore the skeleton of live corals and when penetrating through the wall cause the polyp to deposit additional wall
material that is intended to seal off the borer. The orifice of the burrow may migrate upward along the growing
coral (Grygier & Newman, 1985). Orifice motility is particularly marked in a specimen of Javania
lamprotichum (MUSORSTOM 2 stn 53) bored by 4 large acrothoracids. Other species bored alive are Tethocyathus
virgatus (MUSORSTOM 3 stn 108), Balanophyllia crassiseptum (Karubar stn 50) and Balanophyllia sp.
(Musorstom l stn. 61; Musorstom 2 stn 32; Musorstom 3 stn 131).
Ascothoracidan crustacean inducing a skeleton gall. — The most common aspect of this
association has been described in detail by Zibrowius & Grygier (1985), who already reported some examples
from the Philippines and Indonesia: "internal galls" are recognizable as a spongy proliferation of the columella that
covers the underlying cavity occupied by the parasite. The list from the Philippines and Indonesia now includes :
Deltocyathoides orientalis (" Albatross " stn 5178, 5313, 5314, 5315, 5317, 5403, 5569); Flabellum lamellulosum
(MUSORSTOM 2 stn 83); Balanophyllia carinata ("Siboga" stn 240); Balanophyllia sp.
(Musorstom 2 stn 34); Balanophyllia sp. (MUSORSTOM 3 stn 131); and Dendrophyllia sp. cf. D. ijimai
(Musorstom 2 stn 33). A newly recognized expression (Grygier & Cairns, 1996) of ascothoracidan gall
induction are abnormally hypertrophied corallites in Madrepora oculata (". Albatross " stn 5529; Deki stn 50;
"Hakuho Maru" stn KH-73-2-44-2; KARUBAR stn 9, 13, 19, 77).
Cryptochirid crab inhabiting a crypt in the coral skeleton. — Cryptochirid (formerly
hapalocarcinid) crabs are obligate symbionts of scleractinians. The crypts (or in some cases cage-like galls) they
inhabit are due to dissolution of the coral skeleton and to induced modified coral growth (ZIBROWIUS, 1982;
Zibrowius & Gili, 1990). Previous to these authors, cryptochirids had always been considered as typical of the
reef fauna, but new deep-water species continue to be discovered. Zibrovia galea Kropp & Manning, 1995, has thus
been found on Phyllangia papuensis from the Philippines (MUSORSTOM 2 stn 47) and from Madagascar.
DISTRIBUTION
Regional Diversity. — Vaughan & Wells (1943), ALCOCK (1902c), and Cairns (1989a) have all
suggested that the highest diversity of deep-water corals (azooxanthellates) occurs in the Philippine-Indonesian
region. ALCOCK mentioned the Sulu Archipelago and the Kai Islands as areas with a particularly diversified fauna.
With the possible exception of the New Caledonia-Chesterfield Islands region, which even though a much smaller
region, may have more species, the Philippine-Indonesian region does have the highest recorded number of
azooxanthellate species, i.e., 206 species (Table 1).

AZOOXANTHELLATE SCLERACTINIA
65
Currently, 157 species of azooxanthellate Scleractinia are known from the Philippine Islands (Table 1), which,
when combined with the 410 species of zooxanthellate species known from this country (Veron & HODGSON,
1989), results in 567 species of Scleractinia from this archipelago. 69 of the 157 azooxanthellate species (44%) are
known from a small region north and northeast of Lubang Island, Verde Island Passage, which was intensively
sampled by MUSORSTOM 1, 2 and 3. 66 azooxanthellate species (42%) of the Philippine fauna are recorded from
the Sulu Archipelago, mainly as a result of the "Siboga" and "Albatross" expeditions early in the century.
Cairns (1989a) reported no azooxanthellate species from the eastern coasts of the Philippines (i.e., Pujada Bay,
Mindanao to the Batan Islands); however, the present study indicates 10 such species, primarily found in Leyete
and Lagonoy Gulfs: Fungiacyathus stephanus, Caryophyllia scobinosa, Stephanocyathus regius, S. weberianus,
Deltocyathus magnificus, Rhizosmilia elongata, Peponocyathus minimus, Flabellum deludetis, Truncatoflabellum
incrustatum , and T. formosum.
A total of 174 azooxanthellate species are known from the Indonesian region (Table 1), the most species-rich
subregion being the Banda Sea (138 species) and the most species-rich archipelago the Kai Islands, from which
125 species are known. As can be seen from Table 1, 66 species are known from the Celebes Sea (Sabah) and
Makassar Strait; only 30 from the combined region of the Molucca, Halmahera, and Ceram Seas; 83 from the
Arafura, Timor, and Savu Seas; 5 1 from the Flores and Bali Seas; and 20 from the Java Sea. It is highly probable
that the wide variation in numbers of species for various seas reflects the unequal collecting effort. For example,
the impressive total from the Kai Islands reflects collections made by the "Challenger", "Siboga", Danish
Expedition to the Kei Islands, and the Karubar expeditions, making it one of the most intensively sampled upper
slope areas in the world. Conversely, little collecting has been done in the Java Sea and even less off the southern
coast of Java, which results in low numbers for these regions.
Regional Affinities. — The Philippine-Indonesian region lies at the heart of the largest and most diverse
tropical marine province — the Indo-Polynesian — extending from the Persian Gulf to the Tuamotu Archipelago
(Briggs, 1974). 65 of the 206 species known from this region (31.5%) are also known from the tropical regions
of the Indian Ocean. ALCOCK (1902c) was surprised to discover that only 10% of his Indonesian "Siboga" species
also occurred in the Indian Ocean; later, Cairns (1989a) was able to report an overlap of 25%, and the current ratio
of 31.5% will probably continue to increase as Indian Ocean corals become better known. An even higher number
of Philippine-Indonesian species are found to the north in the warm temperate region of southern Japan (77/206, or
37%). This may be due to the better-known nature of the Japanese fauna (Cairns, 1994) and/or suggests that the
boundaries that distinguish shallow-water tropical and temperate regions do not coincide with boundaries of deep¬
water organisms. The number of shared species with southern tropical regions (i.e., Australia and ridges/islands
north of New Zealand) is similar to that shared with the Indian Ocean (i.e., 67/206, or 32.5%). Only 47 (or 23%)
of the Philippine-Indonesian species are known from other western and central Pacific islands (e.g., Pelau, New
Guinea, Fiji, Hawaiian Islands), which, except for the Hawaiian Islands (Vaughan, 1907; Cairns, 1984), have
been poorly sampled. Only 1 1 Philippine-Indonesian species occur as far east as the west coast of the Americas
(Table 1): of these, 4 are restricted to the Pacific Ocean, 4 have an Indo-Pacific distribution, and 3 are cosmopolitan
in distribution. Of the 1 1 species that also occur in the Atlantic, most (9) are cosmopolitan species, 1 occurs in
the eastern Atlantic and Pacific (i.e., Asterosmilia marchadi), and 1 (i.e., Gardineria paradoxa) is known only from
the western Atlantic and western Pacific. The disjunct nature of the last 2 categories may be the result of inadequate
collection.
Depth Distribution. — 198 azooxanthellate species were scored for their occurrence in 8 bathymetric
zones. The remaining 8 of the 206 species known from this region are not considered because their depth
distribution is unknown or uncertain (Table 1). The results were: 0-100 m (82 species), 100-200 m (89 species),
200-400 m (123 species), 400-600 m (79 species), 600-800 m (40 species), 800-1000 m (25 species), 1000-
2000 m (19 species), and over 2000 m (4 species). When these data are graphed (depth range on the x-axis,
number of species on the y-axis), a bell-shaped curve results, in this case peaking at the 200-400 m category (62%)
and gradually attenuating with greater depth to only 2.5% at over 2000 m. This is consistent with a peak diversity
ol 53% at 200-300 fathoms (= 366-549 m) for Philippine azooxanthellates given by VAUGHAN & WELLS (1943,
table 2), although their data were limited to only 51 species. A similar unpublished analysis of the southwest
66
S. D. CAIRNS & H. ZIBROWIUS
Indian Ocean (Cairns & Keller, 1993) and New Zealand (Cairns, 1995) azooxanthellates results in similar bell¬
shaped curves, but in the case of the southwest Indian Ocean (N = 97), peaking at a shallower depth of 100-200 m
(55%), and for the New Zealand fauna (N=104) at a greater depth of 400-600 m (54%). The bell-shaped maximum
at various depths in different parts of the world is probably correlated with regional water characteristics, especially
temperature.
Although the depth record for a scleractinian coral is 6328 m (KELLER, 1976), only 4 species are known from
the Philippine-Indonesian region at depths slightly in excess of 2000 m: Flabellum conuis (1160-2570 m),
Caryophyllia cornulum (1525-2350 m), Stephanocyathus regius (563-2160 m), and Enallopsammia rostrata (417-
2021 m).

Material EXAMINED. — Philippines. "Albatross"', stn 5277, 1 branch (USNM 96671). — Sin 5381, 1 branch
(USNM 96672).
Type Locality. — West channel of Pelau barrier reef, Pelau, 160 m.
Description. — Corallum ramose, sparsely branched in 3 dimensions; distal branches blunt, 3. 5-4.0 mm in
diameter. Calices circular to slightly elliptical; GCD from 1.07-/. 62-2. 04, with large calices directly adjacent to
some of the smallest. Calices at branch tips relatively close to one another (e.g., 0.3 mm apart), this intercalicular
distance increasing to 1.0- 1.5 mm on large-diameter branches. Coenosteum covered with short (0.15-0.17 mm in
height) spines arranged in rows, 1 row occurring between closely packed distal calices and 3 or 4 rows between
spaced out calices on larger-diameter branches.
Ten primary septa 0.20-0.25 mm exsert and 0.25-0.30 mm in width, their inner edges fused to the massive
columella. In some larger calices traces of secondary septa occur in some interseptal chambers formed by the
primary septa, these secondaries irregular in development, quite small, and having dentate inner edges. Columella
a large dome-shaped structure occupying most of calice and rising slightly above coenosteal level. In centre of
dome is a wedge-shaped columellar lamella that rises as high as primary septa.
Remarks. — Madracis asanoi is similar to M. interjecta Marenzeller, 1907, which is known only from the
Red Sea, but differs in having calices of very unequal size — the calices of M. interjecta being of a uniform size.
M. asanoi is distinguished from M. kauaiensis Vaughan, 1907 (Hawaiian Islands) by having thicker and blunt
terminal branches; a shallower fossa; and nonuniform calicular sizes. The record of M. asanoi from Japan (EGUCHI,
1968) is queried because of its delicate, attenuate branching; deep calicular fossa; and large calices (up to 3 mm).
Madracis palaoensis is considered to be synonymous with M. asanoi given the similarity evident in their re¬
spective illustrations; the differences cited by Yabe & Sugiyama (1936) are considered as intraspecific variation.

Type Locality. — Hvarski Kanal, Adriatic Sea, 36 m.
DIAGNOSIS. — Coralla exclusively encrusting, forming relatively small colonies (usually less than
20 corallites) shaped as: thin, irregular masses; stoloniferous ribbons; or small nodules. Perimeter of colonies
usually enclosed by a smooth, low epithecal lip. Corallites polygonal in shape and 1.5-2. 5 mm in diameter, each
calice sharing a thin (0.07-0.09 mm) common wall with its adjacent calices. Intercalicular walls bear tall (up to
0.2 mm) triangular spines, one corresponding to each of the 20 septa in corallite.
Septa decamerally arranged in 2 cycles (20 septa), the 10 primary septa rising as high as the costal spines, but
their outer edges separated from the costal spines by a deep notch. Inner edges of primary septa smooth and
vertical, each primary bearing a discrete paliform lobe; however, paliform lobes of 5 primary septa are wider and
taller than the lobes of the other 5 alternate primaries, the larger lobes being 0.12-0.15 mm in width, the smaller,
0.06-0.07 mm (Fig. lh). Septal faces covered with tall (40-50 (im), blunt spines. Secondary septa 1/2 to 2/3
width of primaries and much less thick, having dentate to laciniate inner edges. Columella a massive pointed style
rising well above paliform lobes as high as the exsert septa. Columellar style varies from cylindrical to slightly
elliptical or flattened in cross section and is surrounded by a crown of 10 Pi.
Remarks. — Three species of Madracis are characterised as having exclusively encrusting coralla: M. decactis
(Lyman, 1859); M. kirbyi Veron & Pichon, 1976; and M. pharensis. M. pharensis is distinguished from the other
two by having well-developed secondary septa and a distinct ring of Pi. M. kirbyi is also reported from the
Philippines (VERON & HODGSON, 1989), but is not discussed herein because it is considered to be a
zooxanthellate.
Although no skeletal differences could be found between Atlantic and Pacific populations of Madracis reported
herein, the second author believes that characteristics of the soft parts of these populations may ultimately place
the Atlantic and Indo-Pacific populations in different species or subspecies.

Diagnosis. — Corallum ramose, sparsely branched in all directions; distal branches slender and attenuate,
about diameter of a calice. Calices circular to slightly elliptical, 1.75-2.5 mm in GCD, and usually separated by
0.4-0. 5 mm of coenosteum, although calices more crowded near branch tips. Coenosteum spinose. Septa
decamerally arranged in 2 cycles (20 septa). The 10 primary septa are exsert, having spinose faces, each bearing a
small axial paliform lobe. The 10 secondary septa are rudimentary, each expressed as a row of small spines. Fossa
shallow. Columella consists of a central, circular platform from which a pointed, laterally compressed style
projects. 10 Pi encircle the columellar style at the edge of the circular platform.
Remarks. — Madracis sp. A was compared to M. asperula H. Milne Edwards & Haime, 1849 (type locality:
Madeira), primarily because both species have slender branches and decameral symmetry; however, Madracis sp.
A consistently differs in having rudimentary secondary septa and a ring of small Pi. Madracis sp. A is more
similar to M. profunda Zibrowius, 1980 (northeastern Atlantic, 112-327 m), both species having slender branches,
10 primary and 10 small secondary septa. M. sp. A appears to differ in having a distinct crown of Pi. In calicular
features, Madracis sp. A is similar to M. pharensis , but differs significantly in having a ramose corallum.

Suborder FUNGIINA
Superfamily FUNGIOIDEA Dana, 1846
Family FUNGIACYATHIDAE Chevalier, 1987
Genus FUNGIACYATHUS Sars, 1872
Subgenus FUNGIACYATHUS (FUNGIACYATHUS) Sars, 1872
Discussion. — The nominate subgenus has recently been defined (Cairns, 1989a) as including those species
that have 5 cycles of septa (96 septa), the subgenus Bathyactis reserved for those species having 4 cycles of septa
(48). However, the second author suggests that a more meaningful division of the genus would be based on the
characteristic of their septal edges, the nominate subgenus, defined by type species F. fragilis, having corrugated
septa with sinuous edges, and the subgenus Bathyactis, defined by the type species F. symmetricus, having planar
septa with straight edges. Under this suggestion, 3 Recent species would be placed in the nominate subgenus:
F. fragilis, F. stephanus, and F. pliciseptus Keller, 1981, only the last having 4 cycles of septa. The
15 remaining Recent species would be placed in the subgenus Bathyactis, all but 3 having 4 cycles of septa.

DIAGNOSIS. — Two forms of the species occur, one having a flat base and another with a highly concave base.
Corallum large and fragile, the flat-based form up to 62 mm in diameter (Karubar stn 36); concave-based coralla
usually smaller and may have a marginal shelf. Costae consist of thin, finely serrate ridges. Septa hexamerally
arranged in 5 full cycles, the inner septal edges highly sinuous. Each Si bears 20-23 trabecular ridges on each face
and is linked to adjacent septa by 12-15 T-shaped synapticulae. Septal canopies porous and rudimentary. Small P2
usually present adjacent to columella. Columella crispate and flat.
Remarks. — Fungiacyathus stephanus is distinguished from F. paliferus (Alcock, 1902), the only other
Indonesian species having 5 cycles of septa, by having a larger, more fragile corallum; sinuous septa; and smaller
P2. It is more fully described and illustrated by Cairns (1989a, 1994).

base covered with rounded, granular costae. 5 cycles of hexamerally arranged, straight, planar septa. Each Si bears
15-20 trabecular ridges on each face and is linked to its 2 adjacent septa by 9-14 solid synapticulae. Septal canopies
porous and rudimentary. Well-developed P2 and sometimes even P3 present. Columella crispate and rudimentary.
Remarks. — Comparisons to the other species in this subgenus known from the Indonesian region,
F. stephanus (Alcock, 1893), are made in that account and by CAIRNS (1989a, table 1). F. paliferus is more fully

Diagnosis. — Corallum fragile, up to 14.5 mm in GCD; base flat, covered with narrow ridged, serrate costae.
Septa hexamerally arranged in 4 cycles of planar septa, each Si composed of 14-19 trabeculae, the innermost 5 or 6
forming tall exsert spines. Synapticular plates T-shaped, approximately 6 per Si. Columella papillose and rounded.
Remarks. — It was previously thought that 2 of the paralectotypes of Bathyactis sibogae , those from
"Siboga" stn 95 and 159, were missing (Cairns, 1989a: 11); however, in 1994 the specimen from "Siboga"
stn 95 was found in the collections of the ZMA (Coel. 5098). It was mounted on a board along with a specimen
of Flabellum japonicum in a bottle of preservative, filed under the name of the latter species. It is the flat-based
form of Fungiacyathus stephanus and measures about 48 mm in diameter. F. sibogae is more fully described and
illustrated by Cairns (1989a), which also includes a key to the species from this region.
Distribution. — Indonesia : Molucca Sea; Ceram Sea; Banda Sea (Kai Islands and southeast of Sulawesi);

Type Locality. — "Albatross" stn 5590: 4°10'50"N, 1 18°39'35"E (off Sabah, Celebes Sea), 567 m.
Diagnosis. — Corallum robust, up to 24.5 mm in calicular diameter (Karubar stn 40), with a flat to
slightly concave base covered with rounded, granular costae. Septa hexamerally arranged in 4 cycles, each Si
having 21-24 coarsely dentate trabecular ridges on each face and linked to its adjacent septa by 6-9 Y-shaped
synapticulae. Septa planar. Septal canopies porous, but well developed. Paliform lobes absent, but well-developed
trabecular spines present on all septa. Columella large and tuberculate.
Remarks. — As noted by Cairns (1989a), F. granulosus differs from F. sibogae in having a granular base
and beaded costae that are rounded to triangular in cross section, not covered with thin, serrate ridges as in
F. sibogae. Also, F. granulosus attains a larger diameter (24 mm vs 15 mm) and has more robust inner trabecular
spines, especially those of the S2- F. granulosus is more fully described and figured by Cairns (1989a).

adjacent septa by 3 or 4 solid synapticulae. Septa planar. Septal canopies well developed, solid, and inclined.
Paliform lobes absent, but Si trabecular spines well developed. Columella rudimentary.
Remarks. — Fungiacyathus variegatus is distinguished by its relatively small size and its broad, solid
canopies that unite the inner edges of the S3 to their common S2, and the S4 to their common S3. In well-
preserved coralla Si -2 are pigmented a dark brown, but this pigmentation was present on only about 1/3 of the
specimens listed above, the colour apparently fading after the death of the coral. Small coralla (< 4 mm GCD) are
stellate in shape, their Si -2 projecting beyond the otherwise circular calicular perimeter. This species is more fully
described and illustrated by Cairns (1989a).

TYPE Locality. — "Albatross" stn 5586: 4°06’50"N, 1 18°47'20"E (off Sabah, Celebes Sea), 635 m.
DIAGNOSIS. — Corallum robust, relatively small (up to 10.3 mm calicular diameter), with a flat to slightly
concave base covered with rounded granular costae. Costae separated by deep intercostal furrows. Septa hexamerally
arranged in 4 cycles, each Si bearing 20-25 low, serrate trabecular ridges and joined to adjacent septa by 3 or
4 T-shaped synapticulae. Septal edges straight. Septal canopies absent. No paliform lobes, but trabecular spines
robust. Columella well developed, tuberculate.
Remarks. — Fungiacyathus turbinolioides is distinguished from all other species in the genus by having deep
intercostal furrows, which suggests a resemblance to a turbinoliid. It is more fully described and illustrated by
Cairns (1989a).

Type Locality. — Karubar stn 7: 5°47'35"S, 132°20'39"E (Kai Islands, Banda Sea), 282-287 m.
ETYMOLOGY. — The species name fissidiscus (Latin findere, to split + discus, a circular plate) refers to the
tendency of this species to reproduce by fragmentation. The name is considered as a noun in apposition.
Description. — Corallum reproduces primarily by fragmentation (see Remarks), resulting in wedge-shaped
pieces of 6-12 septa that ultimately regenerate into a roughly circular corallum containing 48 septa. Largest
completely regenerated specimen (holotype) 4.9 mm in diameter and 1.7 mm in height. Base flat, often featureless
at centre, but toward peripheral edge formed into well-defined, rounded, granular costae. Costae up to 0.27 mm
wide, separated by deep intercostal furrows about 0.05 mm wide.

Septa hexamerally arranged in 4 cycles. Si extend to centre of fossa, each septum bearing 8-10 trabecular
spines, the innermost spines short, flattened, and curved inward toward fossa; the outer spines are much more
robust and cylindrical in cross section (0.20 mm in diameter). S2 similar to Si in shape, but smaller, extending
only 3/4 distance to centre of fossa, bearing only 7-9 trabecular spines that are less robust than those on the Si.
S3 smallest septa, extending only 1/5 distance to centre of fossa and quite low, bearing only 2 or 3 small
trabecular spines. S4 dimorphic in size, those adjacent to Si being almost as large as Si, bearing 7-9 trabecular
spines, the inner edges of each pair within a system fusing near centre of fossa. S4 adjacent to S2 much smaller
than those adjacent to Si and only marginally larger than the S3, i.e., extending 1/4 distance to centre of fossa,
bearing 4 or 5 trabecular spines. All septa have straight upper edges and highly granular faces. Face granules up to
80pm in height and occasionally bifid, the granules aligned in low ridges only at upper septal edges along
trabecular spines. Approximately 5 solid synapticular plates connect each Si to its adjacent S4, the 4th plate from
corallum centre being the tallest, rising almost to the upper edge of S4. Only 2 synapticular plates connect S2 to
their adjacent S4, and no synapticulae were noted on the S3. Fossa shallow; no columella.
Remarks. — The lack of synapticulae between S3 and their adjacent S4 creates radial lines of weakness
throughout a corallum that are presumed to facilitate the fragmentation process.
Three other species of Fungiacyathus are characterised by having highly regenerative coralla: F. crispus
(Pourtales, 1871): Atlantic, 183-1010 m; F. fissilis Cairns, 1984: Hawaiian Islands, 212-503 m; and F. demand
Cairns & Parker, 1992: South Australia, 190-770 m. F. fissidiscus is distinguished from all 3 in having
intercostal furrows, granular costae, and dimorphic S4. F. fissidiscus is perhaps more similar to F. turbinolioides
Cairns, 1989 (see above), both species having a similar costal structure and septal ornamentation; however, it
differs in having dimorphic S4, a smaller corallum, a regenerative corallum, and in lacking a columella.

Remarks. — One small specimen, a wedge-shaped fragment measuring 3.3 mm in calicular radius, is reported
herein. It appears to be the same species described by Cairns (1989a) from the Celebes Sea. Based on this small
fragment, nothing can be added to the previous description. Four other fragments, too small to identify, are also re¬
ported from Karubar stations 3 (USNM 96728) and 15 (USNM 96729). It is noteworthy that these specimens
represent the shallowest record for Leptopenus (i.e., 214-300 m), a genus customarily found at depths in excess of
2000 m.

Type Locality. — Philippines and Indonesia, 174-236 m.
Diagnosis. — Discoidal corallum up to 50.8 mm in GCD (Karubar stn 35); base flat to slightly convex;
D:H up to 4.9 in large specimens. Thin (0.06-0.07 mm), ridged costae bear very small teeth or short spines,
producing a finely serrate edge; intercostal region quite wide (3-6 times costal width) and porous, the synapticular
bars connecting each costa to its 2 alternating, adjacent septa clearly visible in basal view through intercostal
region. A low, marginal shelf, up to 4 mm wide, present on large, well-preserved specimens. Septa arranged in
typical micrabaciid fashion (Cairns, 1989a, text-fig. 2), attaining the 120-septa stage at a GCD of 17-20 mm and
often maintaining this number; however, a large syntype of GCD 38 mm has 144 septa, and the largest known
specimen of GCD 51 mm has 228 septa. Si independent and unbranched, having a smooth upper, inner edge, but a
spinose peripheral edge. Si of small specimens highly porous, but as corallum increases in size they develop a
more solid, lamellar upper, inner edge — retaining their porosity only on their lower half near the base. S2 also
unbranched but not independent, a pair of S3 fusing to each S2 near the columella. Each S3 bifurcates repeatedly,
producing the majority of the septa. Columella elongate, spongy, and often densely fused.
Remarks. — Letepsammia formosissima was the coral most commonly collected on the MUSORSTOM cruises,
taken at 55 stations ranging from 1 15-390 m. A more complete description and illustrations of this species are
given by Cairns (1989a) and Cairns & Parker (1992), and a comparison to Rhombopsammia niphada is given
in the account of that species.
Another species, L. franki Owens, 1994, occurs in the southwestern Indian Ocean where it had occasionally
been ascribed to L. formosissima (see Cairns, 1989a; Cairns & Keller, 1993; Owens, 1994). L. franki differs
from the latter by its papillose columella and coarse septal dentation that give the corallum a distinctly beaded
appearance.

(MUSORSTOM 2 stn 32) is only 22 mm in calicular diameter and has 96 septa, a size at which L. formosissima
would have 120 septa. Although similar to L. formosissima, L. superstes differs in having a papillose columella,
more robust trabecular spines, and a tendency to have a patellate (vs a flat based) corallum. The species is more
fully described by Cairns (1994) as L. formosissima forma superstes and by Cairns (1995).

(0.06-0.07 mm) ridges. Intercostal regions much wider (about 0.45 mm) than costae, traversed by thin
synapticulae, which produce a series of pores in each elongate space. Marginal shelf present but not wide and often
damaged. Septa arranged in typical micrabaciid fashion (Cairns, 1989a, text-fig. 2), both septa and costae up to

S. D. CAIRNS & H. ZIBROWIUS
Remarks. — The similarities between R. niphada and Letepsammia formosissima have been noted previously
(Owens, 1986a; Cairns, 1989a). R. niphada differs in having solid Si that bear faint vertical ridges (vepreculae)
on their faces, whereas the SI of L. formosissima are highly porous at a small calicular diameter and become more
solid with age, but do not bear vepreculae, and always maintain some porosity adjacent to the base. R. niphada
usually has 144 septa, whereas L. formosissima usually has 120 septa, but as many as 228. R. niphada has
well-developed septal canopies and reduced trabecular spines, whereas L. formosissima has well-developed septal
spines on the S3 and S3' and no canopies. Finally, R. niphada is characteristic of deeper water than
L. formosissima, all records of the former between 405 and 804 m, of the latter species, 97-457 m. A more
detailed description and illustrations of this species are found in OWENS (1986a) and Cairns (1989a).

REMARKS. — Previously known from only 5 specimens from 5 stations, 7 additional specimens of this rarely
collected species are reported herein from the Indonesian region, the largest (Karubar stn 89) 41.2 mm in
calicular diameter. R. squiresi is distinguished from R. niphada by its distinctive marginal shelf, wherein each
septum projects as a broad, flat, spongy mass; and by having only 96 septa.

Diagnosis. — Corallum discoidal, with a thick, flat base and slightly upturned edges; D:H = 1. 9-2.6. Largest
known specimen (" Albatross " stn 5586, Celebes Sea) 15.6 mm in diameter. Costae flat, ornamented with a medial
row of coarse granules close to epicentre, but outward from basal centre each costa bears 2 rows of smaller
granules, one row on each edge of the costa. No marginal shelf. Adjacent septal faces fused together by massive,
elongate mural synapticulae (fulturae sensu Gill, 1979), producing a sturdy, robust corallum. 96 septa arranged in
typical micrabaciid fashion (Cairns, 1989a, text-fig. 3). Septal edges straight; septal face granules wide-based,
equilateral triangular-shaped spines. Columella massive, lenticular to rectangular in cross section, often surrounded
by additional papillae.
Remarks. — Stephanophyllia fungulus is distinguished from the other 2 Recent species in the genus by its

DIAGNOSIS. — Corallum discoidal, with a thin, flat base; D:H = 2. 5-2. 7. Corallum up to 18 mm in calicular
diameter. Costal ornamentation as in S. fungulus Alcock, At calicular edge of well-preserved specimens, costae
are slightly upturned, and bifid, extending about 0.5 mm beyond calicular perimeter and producing a small
marginal shelf. Synapticulae circular to elliptical in cross section. 96 septa arranged in typical micrabaciid fashion,
the S 1-2 having straight edges, but the S3 meandering toward the calicular edge. Septal faces covered with narrow-
based isosceles triangular-shaped granules. Columella a prominent, but thin lamella, sometimes divided into
papillae or sub-lamellar elements at its summit.
Remarks. — All specimens reported above are essentially topotypic, being collected very close to the type
locality in the Kai Islands. S. complicata is distinguished from the other species in the genus (see Cairns, 1989a,
table 2) by having a thin, lamellar columella, and a narrow marginal shelf. It is described in greater detail by
Cairns (1995) based on specimens from the New Zealand region.

Malaysia. Kota Kinabalu, Sabah, depth unknown, 2 colonies (USNM 78565).
Type Locality. — Singapore, South China Sea (depth not given).
DESCRIPTION. — Philippine corallum consists of 50-60 corallites produced by extratentacular, reptoid budding.
Stolons linking corallites thin and flat, 1. 5-2.0 mm wide; corallites spaced 1-5 mm apart. Stolons often covered by
encrusting epifauna. Corallites circular to slightly elliptical in cross section, up to 3.8 mm in GCD, and 4.3 mm
in height. Corallites epithecate when well-preserved, with a very thin (50 pm), almost translucent, smooth upper
rim that rises above upper outer septal edges (fig. 3b).
Septa hexamerally arranged in 4 cycles, the last cycle never complete, 34-42 being the most common septal
complement. Si independent, each composed of a tall but narrow upper lobe, a vertical inner edge, and 1 or
2 laciniate teeth on its lower, inner margin. S2-3 equal in size and shape, the inner edges of the 2 S3 and 1 S2 in

each system fusing near the columella. S2-3 not lobate as the Si, but bearing 3 or 4 laciniate teeth that grade into
the columellar elements. S4 rudimentary, consisting of a discontinuous row of spines, each spine 1/3 to 1/4 height
of the adjacent lower cycle septum. Fossa of moderate depth. Columella papillose, consisting of 5-9 elements
similar in size and shape to innermost septal teeth.
REMARKS. — Dana (1846: 377) described C. stellata as having corallites "3 lines high, and 1.5 broad" and
24 septa per corallite. Since a "line" is 1/12 inch (2.12 mm), the corallites are inferred to be about 6.4 mm in
height and 3.2 mm in GCD. Examination of Dana's holotype (USNM 185) shows it to have shorter (4.3 mm
max.) and broader (to 3.8 mm) corallites, most of which have septa of the 4th cycle, up to 42 septa/corallite.
Likewise, his description of C. truncata implies corallites of 2.6 mm in height and GCD, and 24 septa; whereas
the type (USNM 183) has corallites up to 3.5 mm in GCD and none over 2 mm in height, and most having some
pairs of S4. C. truncata would appear to be a specimen of C. stellata in which the corallites remained slightly
lower than normal, possibly for an environmental reason. The description and figures of C. japonica , as well as the
Japanese specimens reported by Cairns (1994), are also consistent with C. stellata.

Type Locality. — Tyrrhenian Sea and off Sicily (depth not given).
Diagnosis and Remarks. — Madrepora oculata is a widespread, variable species. Many names have beei
used for it (Zibrowius, 1974b) and more recently various forms have also been distinguished (Cairns, 1991). Thi
most commonly collected form occurring in the Philippine/Indonesian region is characterized by having delicate
uniplanar colonies formed of regular, nonanastomosing, sympodially budded corallites (M. tenuis of MOSELEY
1881 and form beta of Cairns, 1991). Its coenosteum is often light beige, finely granular, and longitudinally
striate. It is often attached to long hexactinellid spicules. Corallites 2. 3-3.0 mm in diameter, containing 3 ful
cycles of hexamerally arranged, narrow septa (Si>S2>S3), the CSi-2 usually slightly exsert but extending onl)
about 1 mm down from calice as thin, ridged costae. Inner edges of septa finely dentate to highly laciniate. Septa
faces may also bear tall, slender spines. Fossa of distal corallites usually deep, containing a papillose columella.
Specimens from two lots (Karubar stn 56 and "Albatross" stn 5645) differ from the form described above it
that they live in association with a symbiotic eunicid polychaete, which causes the coral to form a bushy corallun
of highly anastomotic branches.
Specimens from seven lots (Karubar stns 9, 13, 19, 77; "Albatross" stn 5529; "Hakuho Maru" stn 73-2-44
2; and DEKI stn 50) bear some bell-shaped, hypertrophied corallites, as much as 23 mm in GCD and having up tc
82 porous septa. Once reported as the first neoplasms in Scleractinia (SQUIRES, 1965), these abnormally large
corallites are now known to be the manifestation of a parasitic petrarcid ascothoracidan crustacean (Grygier &
Cairns, 1996).
A more complete description and illustrations of this species are found in Zibrowius (1974b) and Cairns
(1982, 1991).

Type Locality. — "Challenger" stn 194: 4°3 1 'S, 129°57'E (Banda Island, Banda Sea), 366 or 658 m.
Description. — Corallum massive, the largest colony (MUSORSTOM 3 stn 126) 26 cm in height, having a
stout, dense basal stem 5.0 cm in diameter. Lower 1/3 to 1/2 of colony consists only of basal stem and individual
corallites that bud directly from the coenosteum, but upper corallum ramifies into anastomosing branches, each of
which contains a central tubular cavity about 5x7 mm in diameter that is presumed to be inhabited by a eunicid
polychaete. Calices 2.5-3. 1 mm in diameter, circular to slightly elliptical, tending to concentrate on one face of the
corallum (here defined as anterior). Whereas corallites do occur on the posterior face, they are fewer in number,
often nonfunctional, filled in with stereome, and usually completely absent from the lower 10 cm of basal stem
due to incorporation within basal coenosteal layering. Coenosteum on distal branches remarkably smooth and
porcellaneous (not granular) even at a magnification of x 2500; however, larger-diameter branches and worn
coenosteum sometimes reveal very shallow longitudinal striae that delimit perfectly flat costae. Septocostal
ridges absent from calicular edges. Corallum white; however, coenosteum immediately adjacent to calice a dark
brown.
Septa hexamerally arranged in 3 complete cycles: S i >S2-3- Si only about 0.4 mm exsert, extremely narrow
(0.10-0.15 mm), having entire (nondentate) inner edges and irregularly granular septal faces. S2-3 nonexsert, only
about 0.06 mm (60 )tm) in width, and otherwise similar to the Si. Deep in fossa the lower, inner edges of the
6 Si and sometimes some of the S2 widen and join one another in centre of fossa, forming a short styliform
columella (Fig. 3f). Deep in fossa S3 are very narrow, each pair within a system bending toward and fusing to its
common S2. Fossa deep and spacious, due to the very narrow septa.
Each polyp possesses 1 long sweeper tentacle, up to 1 1 mm long in the preserved state, the other more typical
tentacles being only 1-2 mm in length. This is the first case of sweeper tentacles being observed in a deep-water
coral.
Remarks. — Madrepora arbuscula differs from other species of Madrepora in several significant characters.
It has: 1) a very massive basal stem, 2) no coenosteal granules, which produces a porcellaneous texture, 3) white
coenosteum but brown-edged calices, 4) extremely narrow septa with no inner edge dentition, 5) a rudimentary
styliform columella (that of M. oculata is papillose), and 6) sweeper tentacles. Although tentacle length of
Madrepora generally had no special attention, the second author has occasionally observed that live M. oculata had
short, uniform-length tentacles. It was therefore surprising to see that M. arbuscula from MUSORSTOM 3 stn 126
had one long sweeper tentacle per polyp in addition to normal-sized, shorter tentacles. This was seen on the freshly
dredged live colonies kept in seawater, and can still be seen after preservation in formalin.
In addition to the ubiquitous spirocysts, both the normal and sweeper tentacles of M. arbuscula (MUSORSTOM
stn 3-126) contain b-rhabdoids (type 1), p-rhabdoids D (type 1), and holotrichs (type I). According to DEN Hartog
(1977), the cnidae of sweeper tentacles are always different from that of normal tentacles, so M. arbuscula may
present a unique condition among the approximately 14 scleractinian species now known to have sweeper tentacles
(Williams, 1991). Nematocyst identifications and terminology follows the review by Pirez and Pitombo (1992)
and is considered only preliminary — the quantification of sizes remains to be tabulated.
Madrepora arbuscula (Moseley, 1881) is a junior secondary homonym of M. arbuscula Dana, 1846, but because
Dana s species is now considered to be in the genus Acropora, according to the ICZN (article 59c) Moseley’s
name does not have to be replaced.

(1 or 2 on the parent corallite), on trunk and main branches corallites immersed into sclerenchyme. Corallum solid
with smooth surface; no costae. White, except for pigmented calicular edge or upper 1/2 of sympodial corallites
Pigmentation reddish brown to dark brown, extending throughout the skeleton thickness at the pigmented level
not only superficial; also extending inside calice on septa. Pigmentation of septa decreasing in depth of calice
Corallites on thin branches about equal in height and width, 1. 5-2.5 mm in calicular diameter, with a narrow base
and up to 2.5 mm in height. Corallites distinctly infundibuliform, with wide "empty" fossa because of the low
septa. Septa are essentially reduced to a row of flattened septal edge teeth coalescent laterally with granules of the
reduced septal faces. Septa hexamerally arranged in 3 complete cycles, as ridges of low papillae rather than distinct
lamellae. Si to S3 slightly decreasing in width, with a correspondingly slight decrease in exsertness above the
calicular edge. No columella, bottom of fossa covered by small papillae similar to those of the higher and more
peripheral parts of the septa.
CORINDON 2 stn 248 provided 1 small branch (21 mm in length) with the eunicid-induced deformation and
comprising ca. 20 calices, of the typical aspect. But from the same station there is another small colony about
15 mm in height with the same type of deformation, the calices of which are exceptionally small (1 mm or less in
diameter), with only 12 septa. These septa are similar to those in typical M. minutiseptum with 24 septa (i.e., as
in the branch from CORINDON 2 stn 248) by being very low and denticulate. This unique specimen may be an
initial colony of the same species, dwarfed for some reason. For this reason it is not given paratype status.
Remarks. — Although differing considerably from the type of the genus, Madrepora oculata , the species in
question is attributed herein, provisionally, to the genus Madrepora on the basis of a series of characters: the small
sized corallites arranged in sympodial branches, septa in 3 cycles, the general shape of colonies, and the regular
presence of a not yet observed symbiont which causes the tubular growth deformation and which is presumed to be
an eunicid polychaete. M. minutiseptum differs from all congeners by its very low septa which are hardly more
than a denticulate ridge. Like M. arbuscula , it is partly pigmented (near the calicular edge).

AZOOXANTHELLATE SCLERACTINIA

The species described here under Madrepora minutiseptum had recognizably been characterized and illustrated by
Saville Kent (1871) as a scleractinian under the name Amphihelia infundibulifera, on the basis of "specimens in
the British Museum, collected at Formosa by Consul Swinhoe" (material which we have seen). Saville Kent
was mistaken in being convinced that his material was "evidently identical with the species described .. by
Lamarck", i.e., Oculina infundibulifera Lamarck, 1816, presumed to come from the Indian Ocean. Lamarck's
(1816: 286) text in Latin and French (the same in the 2nd edition, 1836: 457, without additions) is brief and im¬
precise, as usual for most coral descriptions in the early 19th century. A critical analysis of this text strongly
suggests that Lamarck's O. infundibulifera is not a scleractinian but a stylasterid coral (at that time stylasterids
were not yet recognized as a distinct group). O. infundibulifera was said to be close to the "following" species,
O. flabelliformis Lamarck, 1816 (now Stylaster flabelliformis; for a detailed description, including of
Lamarck's type, see Boschma, 1957b); to be almost flabellate; and to have very small zigzag-shaped branches
aside the thicker main ones, both of which are coalescent. All this characterizes a stylasterid rather than a
scleractinian.
Lamarck's O. infundibulifera was mentioned by H. Milne Edwards & Haime (1857: 131) as a
problematical stylasterid under the combination Allopora (Stylaster) infundibulifera. Having not seen
Lamarck's type, they referred to Dana (1848) for this interpretation. Lamarck's type of O. infundibulifera
appears lost. It is not with the LAMARCK collection at the Museum national d'Histoire naturelle, Paris. It probably
has never been there since Lamarck's text does not indicate "Mus. no.", his usual way of referring to specimens
present in the MNHN collection.
Many (not all) secondary quotations of Lamarck's species are listed by Boschma (1957a: 62-63, under
Amphelia infundibulifera) who, following Saville Kent (1871), considered it as a scleractinian. But, given the
strong arguments for Lamarck's O. infundibulifera being a stylasterid, this name cannot be used for Saville
Kent's species which is a Madrepora ( = Amphihelia).
Should there be another old name available for Saville Kent's scleractinian? Ehrenberg (1834: 302-303)
distinguished 4 new varieties of Oculina virginea (this name dates back to Madrepora virginea Linnaeus, 1758, an
unidentifiable taxon): pachyclados, leptoclados, tubulifera, immersa. As typical for Ehrenberg's taxa, the
characterization of these 4 varieties is too brief to allow adequate identification based on his text alone, O. virginea
being itself a confused taxon since the beginning.
The Berlin Museum possesses 5 colonies referable to 2 species of Madrepora (= Amphihelia) and considered as
being part of the museum's initial collection studied by Ehrenberg (1834). All are without indication of origin,
as common at that time of "natural history cabinets", and 4 of them are ascribed to GERRESHEIM, an early
19th century collector. The 2 species in question are: Madrepora oculata Linnaeus, 1758 (see Cairns, 1979;
Zibrowius, 1980) represented by 4 colonies, and M. "infiindibulifera" sensu Saville Kent, 1871, represented by
one colony. Only one colony (of M. oculata) is accompanied by a label in EHRENBERG's handwriting, reading
Oculina virginea Lam. (but no variety is indicated). The 4 other colonies (3 M. oculata; 1 M. "infundibulifera"
sensu Saville Kent) all have later 19th century, not original, labels reading Oculina virginea var. leptoclados.
It cannot be elucidated whether the identification of colonies of 2 distinct species to var. leptoclados was by
Ehrenberg himself or was due to some later confusion. Ehrenberg's characterization ( ramis tenuioribus ; Latin:
with thinner branches) of var. leptoclados (Greek: thin branch), opposed to the characterization ( ramis crassioribus ;
Latin: with thicker branches) of var. pachyclados (Greek: thick branch) is of no help, especially since no
authentically labeled sample of var. pachyclados is present that could be the reference. Accordingly the only colony
(ZMB 582, Gerresheim) of M. "infundibulifera" sensu Saville Kent in the old Berlin collection should not be
considered as the type of Ehrenberg’s var. leptoclados and this name is rejected as unavailable for SAVILLE
Kents species. The latter is here named Madrepora minutiseptum because of its very reduced low septa.
Distribution. — Remarkably, this species is represented by quite a number of colonies in several old
museum collections (Berlin, Amsterdam, London, Sydney, Wien), received in the 19th century. A few more
specimens were collected in the 1980's. Although there is no modern record from the area, Taiwan (= Formosa) as
the origin of a series of colonies at the BMNH received from "consul Swinhoe" is surely correct since Robert
S\ tnhoe (1836-1877) had indeed been on duty in China for many years, including in Taiwan (in 1858, 1861 and
1864-1866, especially at Tansui, in the north of the island; see Mearns & Mearns, 1988).

Type Locality. — Eastern Indian Ocean (depth not given).
Diagnosis. — Corallum sparsely branched, resulting in small, robust, bushy colonies, the largest knowr
7.5 cm in height, consisting of about 100 corallites (EGUCHI, 1968). Extratentacular branching essentially
sympodial, 2 buds usually originating on opposite sides of a terminal corallite, the parent corallite eventually
becoming immersed in thick coenosteum in resultant branch axil. Corallites relatively large, up to 11 mm GCD
Corallum light brown, the corallites usually a darker shade. Septa hexamerally arranged in 4 cycles: Si-2>S3>S4
A crown of 12 thick pali (P1-2) encircle the columella and a second, slightly more recessed crown of 12 P3 stand
higher in the fossa, resembling the calice of a Trochocyathus. Columella papillose.
REMARKS. — Among the colonial azooxanthellate corals known from this region, Cyathelia is distinguished
by its distinctive branching: two large corallites budding from opposite sides of a parent corallite, the parent
corallite often becoming constricted. Also distinctive, the coenosteum of this species is white to beige, whereas
the calice and near-calice coenosteum are a darker brown. A complete description is given by NEMENZO (1979) and
Cairns (1994).

DESCRIPTION. — Corallum up to 5 cm in height, forming a very thin, easily fractured encrustation around the
parchment-like tube of a eunicid polychaete or gorgonian axis. Only very short, slender branches consisting
of 3-5 corallites project from the basal encrustation. If encrusting a polychaete tube, the terminal aperture
created by the polychaete is approximately 2.8 mm in diameter; however, additional circular to elliptical
pores of variable diameter (0.4- 1.6 mm) penetrate the coenosteum providing feeding apertures for the worm.
Calices circular but variable in diameter, ranging from 0.70-1.50 mm. Theca white, with very faint, longitudinal
costal striations. Coenosteum of some coralla also densely covered with small, blunt papillae up to 70 pm
in diameter and 80 pm in height, similar to the "granular echinulations" illustrated by Pratt (1900: pi. 62,
fig. 2).
Septa hexamerally arranged in 3 generally full cycles: Si>S2>S3; in some corallites from Ambon (ZMUC),
1 or 2 pairs of S3 are sometimes missing, resulting in 20-22 septa. Si highly exsert (up to 0.25 mm) and quite
narrow (about 0.11 mm). Vertical inner edges of Si slightly thickened and sinuous deep in fossa, where they
extend to the centre of fossa. S2 less exsert and narrower (about 0.6 mm) than the Si, not extending quite as far
toward centre of fossa. S3 least exsert and least wide (about 0.4 mm) septa, attenuating before they reach base of
fossa. Fossa relatively shallow and quite wide, resulting from the small size of the septa; fossa with a horizontal
floor. Columella rudimentary, consisting of several irregularly shaped papillae, the papillae often an extension of
the inner Si septal edges.
Remarks. — Both Moseley (1881) and Pratt (1900) reported their Vanuatu specimens of N. porcellana
to have exclusively pentameral symmetry in 3 cycles (5:5:10), resulting in 20 septa, although PRATT (1900: 592)
acknowledged that "there is a tendency for them to lose their symmetry of arrangement". Likewise, most of
Wells' (1984) Pleistocene Vanuatu specimens (USNM) have 20 septa, but several corallites were found
to have 24 septa arranged in three cycles. Whereas most of the Ambon corallites have hexameral symmetry
in 3 cycles (24 septa), the 3rd cycle is occasionally incomplete, resulting in 20, 22, or 24 septa. Because
of the difference in septal symmetry (pentameral resulting in 20 septa for previously reported
Neohelia vs. hexameral resulting in 24 septa) the Indonesian specimens are not definitively identified as
N. porcellana.
Some early authors (PRATT, 1900; HICKSON, 1903) believed that N. porcellana was able to produce a horny
membrane underlying its calcareous coenosteum. In fact, similar to Madrepora , Neohelia may overgrow the
productions of other organisms and especially the membrane-like tubes of symbiotic eunicid polychaetes.
However, more recently, polychaetes have been found within Madrepora axes (CAIRNS, 1991, 1995) and, indeed, a
dried eunicid was found in the tube of the Neohelia from Ambon, suggesting that the polychaete, not the coral,
secretes the homy membrane.
WELLS (1984) synonymised Neohelia with Madrepora without explanation. The rudimentary columella in
Neohelia and its distinctive coenosteal papillae would seem to justify the retention of this genus. Neohelia
porcellana is described in great detail by Pratt (1900), including characteristics of the soft parts.
Distribution. — Indonesia : Makassar Strait; Banda Sea (Bay of Ambon: Solar Strait); Timor Sea (southeast
of Timor); Lintah Strait, west of Flores; 55-170 m.
Typical pentameral Neohelia porcellana is known from Vanuatu (Api Island, type locality) (Fig. 50 and
Pleistocene of Kere and Navaka River (WELLS, 1984); Loyalty Islands (PRATT, 1900; HICKSON, 1903); and New
Caledonia. Wells (1984) listed N. porcellana from northwestern Australia (140-141 m), but we can find no
documentation of this record. According to MOSELEY (1881) the types were collected at "Challenger" stn 177 at
63 fathoms (=115 m), but according to TIZZARD et al. (1885, cruise narrative) it is 130 fathoms (= 238 m).
Vaughan & Wells (1943) indicate a range of 91-1 15 m for the species, but again without documentation. The
only reliable depth range for the species is that of the types: 1 15-238 m.

but largest from Indonesian region only 12 mm in GCD and 21 mm in height. PD:GCD = 0.26-0.40. Costae fla
and poorly distinguished, covered with inconspicuous granules, sometimes porcellaneous. Septa hexamerally ar¬
ranged in 4 full cycles: Si-2>S3>S4- S3 have highly sinuous inner edges, those of S 1-2,4 less sinuous. Septa only
moderately exsert. A tight crown of 12 P3 encircle a fascicular columella of 3-12 slender lamellae. Fossa shallow.
Remarks. — Among the 56 Recent species of Caryophyllia listed by Cairns (1991), the largest subset
(19 species) are those species having attached coralla and hexamerally arranged septa in 4 cycles. C. diomedeae
belongs to this morphological subset, as do the first 3 species in the account of this genus, the 4th (C. lamellifera )
having both hexameral and heptameral symmetry. C. diomedeae can be distinguished from other species in this
region using the key.
DISTRIBUTION. — Philippines: Lubang Island; Verde Island Passage; Sulu Sea (Sulu Archipelago); 330-
865 m. Indonesia: Ceram Sea (south of Obi Islands); Banda Sea (Kai Islands); Teluk Bone (Sulawesi); Savu Sea

DIAGNOSIS. — Corallum ceratoid to subcylindrical; largest known specimen (Karubar stn 31) 8.8 x
10.8 mm in calicular diameter and 14.1 mm in height. PD:GCD = 0.50-0.81. Theca porcellaneous, covered with
low, rounded granules. Corallum white, but often having a light brown calicular edge. Septa hexamerally arranged
in 4 complete cycles: Si>S2>S4^S3- Si highly exsert, forming triangular calicular lancets. Inner septal edges
only slightly sinuous. A tight crown of 12 slender P3 encircle a fascicular columella composed of 3-9 very slender
twisted lamellae. P3 appear to be paired within each system. Fossa extremely deep and narrow.
REMARKS. — Caryophyllia crosnieri is more fully described and illustrated by CAIRNS & KELLER (1993) and
CAIRNS (1995) as C. elongata. The name elongata Cairns in CAIRNS & KELLER (1993) is a junior primary
homonym of Caryophyllia clavus var. elongata Duncan, 1873, and thus is replaced herein. This species is renamed
for Alain CROSNIER (MNHN), one of the driving forces behind the MUSORSTOM expeditions and the resultant
publications. The species also occurs in Madagascar, Indonesia, Philippines, and New Caledonia, areas where he
contributed to the collection of deep-water benthos.
Caryophyllia crosnieri is distinguished from its congeners by having an extremely deep fossa and small "paired"
pali (see key).
Distribution. — Philippines : Mindoro Strait; 326-330 m. Indonesia: Banda Sea (Kai Islands); 206-296 m.

Type Locality. — "Albatross" stn 5265: 13°41'N, 120°00'E (Lubang Island, Philippines), 247 m.
Etymology. — The species name secta (Latin sectus, cut) refers to the base of the anthocyathus stage, which
appears to be cut from the anthocaulus.
Description. — Anthocaulus stage unknown, probably not collected because of its small size. Corallum
(anthocyathus) elongate-conical (edge angle 24°-36°), straight, and always unattached, the pedicel narrowing to a
small circular to elliptical detachment scar 2.0-2.5 x 2. 2-3.4 mm in diameter. Holotype 15.7 x 12.9 mm in
calicular diameter and 21 mm in height; largest calice (KARUBAR stn 3) 17.6 mm in GCD, and largest corallum
(Musorstom 3 stn 126) 30.0 mm in height. Calice elliptical: GCD:LCD = 1.19-7.24-1.39 (N=6). Costae flat to
onij slightly convex, each about 0.85 mm wide near calice and separated by very thin, shallow striae. Costae
90
S. D. CAIRNS & H. ZIBROWIUS
covered with low, rounded granules — 4 or 5 occurring across width of a costa near calice. Thin porcellaneou
epithecal bands present on well-preserved coralla. Corallum white to light reddish-brown.
Septa usually hexamerally arranged in 4 complete cycles of 48 septa according to formula: Si-2>S3>S4; onb
one corallum (Karubar stn 3) having 14 sectors, or 56 septa and 14 pali. Septa evenly and widely spaced
0.6-0.7 mm from one another. Si -2 only slightly exsert (1.1 -1.2 mm), extending about 3/4 distance to columella
having moderately sinuous inner edges. S3 and S4 equally exsert (about 0.8 mm), the S3 about 3/4 width of S1-2
having very sinuous inner edges. S4 3/4 to 4/5 width of an S3, inner edges moderately sinuous. Septal face
covered with small, pointed granules arranged in closely-spaced, parallel rows in a fan system radiating from th
thecal wall. An elliptical crown on 12 lamellar P3 encircle the elongate columella, each palus having a slightl
sinuous inner and outer edge and measuring 1.0- 1.3 mm in width. Fossa shallow to moderate in depth. Columell
consists of 4-9 slender, twisted lamellae.
Remarks. — The nature of the base of C. secta is unique within Caryophyllia. If only one specimen wer
found to be truncate, with a small, basal scar, it might be interpreted as an accidental fracture from the substraturr
but its presence in all specimens reported above suggests that it is a normal feature of the species. Basal scars ar
assumed to have resulted from transverse division from a small, attached anthocaulus stage; however, no such stag
has yet been identified for this species.

Zamboanga Peninsula); 220-366 m. Indonesia-. Banda Sea (Kai Islands); Bali Sea; 240-278 m.

1995); largest reported herein (MUSORSTOM 3 stn 134) 11.5 mm in GCD and 17.2 mm in height. PD:GCD =
0.38-0.53. Theca glisteny, covered with closely spaced, transverse ridges. Most coralla have brown thecal striping
and brown Si -2. Septal symmetry variable, most specimens reported above having 4 cycles of heptamerally
arranged septa (56 septa, 14 pali), but one small specimen (Karubar stn 18) having hexamerally arranged septa
(48 septa, 12 pali). Septal formula: Si>S2>S3>S4, the S1-2 highly exsert, forming triangular calicular lancets
with their flanking S4. Inner edges of all septa slightly sinuous. 12 to 14 robust P3 encircle a fascicular columella
composed of 1-19 very slender twisted lamellae. Fossa of moderate depth.
REMARKS. — This species is more fully described and illustrated by CAIRNS (1995). It is distinguished by its
relatively large, pigmented corallum and its transverse thecal ridging (see key).

TYPE Locality. — "Challenger" stn 192: 5°42'S, 132°25'E (Kai Islands, Banda Sea), 235 m.
Description. — Corallum trochoid (edge angle 53°-65°), straight, and always attached through a narrow
pedicel 1.6-2. 9 mm in diameter (PD:GCD = 0.11-0.19). Substratum often a small scaphopod, gastropod, or
bivalve shell. Calice elliptical: GCD:LCD = 1.21-7.27-1.36 (N=6). Largest known specimen (Karubar stn 79)
21.6 x 15.9 mm in calicular diameter and 23.8 mm in height, with a pedicel diameter of 2.7 mm. Costae flat to
slightly convex, each about 1 .0 mm wide near the calice of a large specimen, and separated by thin, shallow striae.
Costae covered with low, rounded, glisteny granules — 4 or 5 occurring across a costa. Corallum near calice of
large specimens beige, becoming white or discoloured 4-5 mm below calicular edge.
Septa, even of coralla as small as 8.8 mm GCD, arranged accordingly: 14:14:28 (56 septa and 14 pali);
however, 1 large corallum from Karubar stn 67 has 16 primary septa and 16 pali, and altogether in 60 septa.
Primary septa highly exsert (up to 3.5 mm), with straight, vertical inner edges that attain the columella low
in fossa. Secondary septa least exsert (about 1.3 mm), about 3/4 width of a primary, with highly sinuous inner
edges. Tertiary septa about 2 mm exsert, each pair adjacent to a primary fusing to that primary in a low, triangular
calicular lancet, producing a serrate calicular margin. Tertiary septa about 4/5 width of a secondary, with straight
inner edges. An elliptical crown of 14-16 P3 encircles an elongate columella, each palus about 1.7 mm wide,
having highly sinuous edges. Fossa of moderate depth, containing a columella of 9-15 slender, closely-spaced
twisted lamellae.
Remarks. — Caryophyllia transversalis is similar to C. secta sp. nov., but can be distinguished by its
attached, trochoid (vs unattached, ceratoid) corallum; lanceted calicular edge; and tendency to have 14 (vs 12)
primary septa. Among the Recent Caryophyllia , attached species having decatetrameral symmetry (x 14) are not
common, only three being listed by Cairns (1991, table 3), all of those species having a range of septal
symmetry that includes decatetrameral.

Remarks. — Caryophyllia rugosa is a very common azooxanthellate coral found throughout the Indo-We t
Pacific, characterised by having a relatively small corallum, 3 cycles of very sinuous, octamerally arranged sept ,
and a transversely ridged theca. The 5 species of attached Caryophyllia having octamerally symmetrical septa ai

ETYMOLOGY. — The species name octonaria (Latin octonarius, consisting of 8 units) refers to the octamer 1
symmetry of this species.
DESCRIPTION. — Corallum conical, straight to slightly bent, and always attached by a slender pedic I
(PD:GCD = 0.26-0.5/-0.40). Coralla always attached to gastropod or bivalve shells; one dead corallun
(MUSORSTOM 2 stn 2) secondarily incorporated into a Xenophora shell. Calice slightly elliptical: GCD:LCD =
1.06-/. 08- 1.1 3. Largest known specimen (the holotype) 7.8 x 8.4 mm in calicular diameter, 13.9 mm in heigh ,
and 2.2 mm in pedicel diameter. Costae not well defined, the theca often smooth and porcellaneous near calic .
Costae on lower corallum equal in width (0. 5-0.6 mm) and flat, separated by very shallow, narrow intercostal strire
and covered with low, rounded granules. Theca light grey-brown or reddish-brown; septa, pali, and columella
usually white.
Septa octamerally arranged in 3 complete cycles (32 septa) in all specimens examined. Eight primary sepia
relatively highly exsert (1.7-2. 2 mm), extend about 3/4 distance to columella, having moderately sinuous inner
edges. Remaining septa equally exsert (1.0- 1.2 mm), the 8 secondaries being about 5/6 width of a primary, also
having moderately sinuous inner edges. Tertiary septa of small coralla equal to or slightly less wide than
secondaries, but at a later stage its tertiaries become slightly wider than its secondaries (Si>S3>S2). Inner edges of
tertiaries only slightly sinuous. Septal faces covered with prominent, pointed granules. Fossa quite shallow,
containing an elliptical crown of 8 sinuous pali before the secondaries, each palus 1.0- 1.1 mm wide. The fascicular
columella consists of a field of 6-9 twisted elements strongly fused together basally.
Remarks. — There are 4 previously described octamerally symmetrical, attached Caryophyllia: C. rugosa
Moseley, 1881; C. barbadensis Cairns, 1979; C. octopali Vaughan, 1907; and C. marmorea Cairns, 1984, all of
which are characterised by having their tertiaries equal to or wider than their secondaries. C. octonaria is similar lo
C. octopali, but differs in having a narrower pedicel (PD:GCD = 0.26-0.40 vs >0.5 for C. octopali ), a more flared
corallum (that of C. octopali is elongate and subcylindrical), and in having relatively exsert septa. In the last
character C. octonaria resembles C. octopali var. incerta Vaughan, 1907, but that form differs in having hexameral
or heptameral symmetry, a very reduced columella, and a quasicolonial habit.

exsert, forming calicular lancets with adjacent pairs of S4. A crown of wide, lamellar P3 encircles a fasciculi -
columella of 4-14 relatively broad, twisted elements.
Remarks. — Caryophyllia scobinosa is more fully described, illustrated, and discussed by Cairns (199‘ ,
1995), and compared to Caryophyllia cornulum sp. nov. in the following account.
The second author believes that this taxon is a species complex, composed of several morphologically distint 1
species that are also bathymetrically distinct.

ETYMOLOGY. — The species name (Latin cornulum , small horn) refers to the shape of the corallum. The name
is treated as a noun in apposition.
Description. — Corallum ceratoid, unattached, and rarely curved more than 45°, the base of all but
1 specimens being strongly eroded; the base of one specimen (CORINDON 2 stn 220) is 1.5 mm in diameter and
shows 6 protosepta in the basal disc. Corallum of most specimens medium to small in size, the holotype only
15.3 x 17.9 mm in calicular diameter and 16.5 mm in height; however, the 8 Japanese specimens are larger, one
up to 27 mm in GCD. Calice slightly elliptical: GCD:LCD = 1.06-1.18. Costae well preserved only near calice,
where they are about 0.6 mm wide, separated by thin, shallow striae and covered with small granules. Below 2 mm

from the calicular edge the corallum is usually eroded, becoming grayish in color. Primary costae sometimes
slightly ridged.
Septal arrangement variable, the most common complement being: 14:14:28, and 14 pali, shared by 1 1 of the
30 specimens analyzed. Nine specimens have 16 primary septa (up to 64 septa); the 8 Japanese specimens have
only 12 primary septa (48 septa); 1 has 13 primary septa (52 septa); and 1 has 18 primary septa (72 septa). It is
common, however, for 1 or more sectors to lack its tertiary pair of septa and corresponding palus, resulting in
septal and palar complements that fall short of the expected for that number of primary septa (e.g., a corallum
having 16 primary and 16 secondary septa, may have only 28 or 30 (instead of 32) tertiary septa and only 14 pali).
Primary septa little exsert (1.0- 1.1 mm), extending only about 1/2 distance to columella, having straight to
slightly sinuous inner edges. Secondary and tertiary septa equally exsert (0.7-0.8 mm), producing a low, serrate
calicular margin. Secondaries about 1/2 width of a primary septum, having slightly sinuous inner edges; tertiaries
equal to or slightly wider than a secondary, having slightly sinuous inner edges. A crown of 12-18 (usually 14-16)
wide pali occurs before the secondary septa, the pali usually wider (2.2-2. 8 mm) than septa they border. Palar edges
slightly sinuous, their faces bearing a granulation coarser than that of septa. Columella fascicular, composed of 1-7
(usually 2 or 3) broad, twisted elements, often arranged in a line.
Remarks. — Caryophyllia cornulum is similar to C. scobinosa but differs in having: much less exsert septa
that do not form calicular lancets; a tendency to have 14-16 primary septa (vs 12 for the typical form); a less
curved corallum with a strongly eroded base; and a deeper bathymetric range (1525-2576 m vs 353-1276 m for
C. scobinosa). Although some large specimens of C. scobinosa occasionally have 14 or 16 primary septa
(CAIRNS, 1995), even small specimens of C. cornulum have 14-16 primary septa, only the Japanese specimens
having 12 primary septa.

Type Locality. — Laccadive Sea, Arabian Sea, 1829-1957 m.
Diagnosis. — Corallum massive (GCD up to 60 mm) and curved, having a pointed and/or eroded base. Ci-3
usually slightly ridged. Coralla contain 18-30 (but usually 24) primary septa, an equal number of secondaries, and
twice that number of tertiaries, resulting in calices with 72-120 (but usually 96) septa. Tertiary septa equal to or
wider than secondaries, but always more exsert than secondaries, fusing with their flanking primary septum to
form highly exsert lancets. A broad palus occurs before each secondary septum, each of the 18-24-30 pali usually
wider than the septa they border. Fascicular columella composed of numerous, broad, twisted elements.
Remarks. — Cairns (1994, 1995) redescribed what he believed to be the nominate subspecies of
C. ambrosia. It appears to be a widespread Pacific and Atlantic species with regional variation regarding corallum
size and number of septa (Cairns, 1995). The Philippine/Indonesian specimens are the largest thus far recorded, up
to 60 mm in GCD and containing 130 septa, which makes them most similar to those reported from New Zealand
96
S. D. CAIRNS & H. ZIBROWIUS
(CAIRNS, 1995). However, the second author believes that "C. ambrosia" may represent a species complex, th
coralla of which are similar to virtually indistinguishable, and the species of this complex having more restricte 1
geographic and bathymetric ranges. Characteristics of the soft parts or molecules may be necessary to resolve th'
taxonomic issue.
C. ambrosia is compared to C. grandis in the account of the latter species.

DIAGNOSIS. — Corallum large (GCD up to 50 mm), sometimes free and curved, but more often straight t >
slightly bent, and attached by a narrow pedicel 1.8-6. 5 mm in diameter. Ci-3 usually slightly ridged. Upper thee i
and septal faces light beige; lower theca white or discoloured. Septa usually hexamerally arranged in 5 cycle t
(Si -3>S4>Ss), but some large coralla have up to 28 primary septa and a total of 1 12 septa. S5 narrower than S. .
but more exsert, fusing with their adjacent Si -3 to form highly exsert lancets. 24 P3, which are usually narrower
than the S3 they border, form a crown encircling a fascicular columella composed of broad, twisted lamellae.
Remarks. — Caryophyllia grandis is distinguished from C. ambrosia by its: attached, reinforced pedice :
highest cycle septa (i.e., S5) that are narrower than their S4; narrower pali; brownish theca; and usually straighte ,
less curved, corallum. In the Indonesian region C. grandis is also found at shallower depths than C. ambrosia: 25 1 -
567 m vs 468-1048 m, respectively.
DISTRIBUTION. — Indonesia: Arafura Sea (southeast of Tanimbar Islands); 251-567 m. Elsewhere: Malaysia
(Celebes Sea off Sabah); Indian Ocean from South Africa to western Sumatra; 183-595 m.

Type Locality. — Unknown.
Diagnosis. — Corallum ceratoid, compressed (GCD:LCD = 1.3- 1.5), and usually curved in plane of GCD.
Largest Philippine specimen (MUSORSTOM 1 stn 56) 16.7 x 21.4 mm in calicular diameter and 24.9 mm in
height. Corallum either attached to a small object through a slender pedicel 1.5- 1.8 mm in diameter or secondarily
unattached. Thecal edges rounded, the concave edge with 2 or 3 elongate spines, the convex edge bearing
3-5 elongate spines. Edge spines circular to elliptical in cross section. Costae rounded, not ridged. Septa usually
arranged in 14 sectors: 14:14:28 (56 septa), with 14 pali; however, a large specimen from Japan (BMNH
1840.9.29.42) with a GCD of 22.3 mm has 16 pali and a septal complement of 64. Primary septa highly exsert,
forming small (up to 3 mm) calicular lancets. Pairs of quaternary septa sometimes present in end half-systems.
A distinct crown of 14 pali occurs before secondary septa, encircling an elongate fascicular columella composed of
7-10 highly fused (basally), twisted elements.
Remarks. Caryophyllia (A.) grayi is distinguished from C. (A.) spinigera by having: more septa and pali
(usually 56 septa and 14 pali vs 48 septa and 12 pali for C. spinigera ); low, rounded Ct-2 (not ridged as in
' sP'n'8era)< a gently curved corallum in the plane of the GCD and thus an asymmetrical arrangement of thecal
e ge spines, cylindrical, not spatulate, thecal edge spines; the absence of lateral face thecal spines; a brownish
cora urn (corallum of C. spinigera is more gray); and equally developed primary septa (the 6 St of C. spinigera
are muc i more exsert than their 6 S2). C. (A.) grayi is more fully described and illustrated by Cairns (1994).
aryophyUia (A.) guangdongensis Zou, 1984, known only from the northern South China Sea (167-179 m), is
in erine iate between C. spinigera and C. grayi . It resembles C. spinigera in having spatulate edge spines and only
98
S. D. CAIRNS & H. ZIBROWIUS
48 septa with 12 pali, but differs from C. spinigera (and is thus similar to C. grayi) in having: convex, rounde I
Ci-2, equal-sized Si and S2, less exsert S1-2, and no thecal face spines.
Five more species are recognised in this subgenus: 4 having edge crests, not spines: C. (A.) spinicaren >
(Moseley, 1881), C. (A.) zanzibarensis Zou, 1984, C. (A.) karubarica sp. nov. and C. (A.) unicristata sp. nov .
and one having spines on only one thecal edge: C. (A.) dentata (Moseley, 1881). A 9th possible species, reportc 1
as Caryophyllia laoagana Smith, 1913, from the Pleistocene of the Philippines, may also belong to th
subgenus, but the single type specimen is very poorly preserved. The second author suggests that only the i
species having edge spines should be placed in the subgenus Acanthocyathus , the 4 species listed that have ed<
crests belonging more properly to the nominate subgenus.

DESCRIPTION. — Corallum compressed (GCD:LCD = 1.3- 1.5) and usually slightly curved in plane of GCD,
but rarely more than 90°. Holotype (BMNH 1880.11.25.42) 11 mm in GCD; largest known specimen (DEKI
stn 3) 9.4 x 12.3 mm in calicular diameter. Pedicel quite small (1.2- 1.5 mm in diameter) and circular in cro s
section. C1-2 of holotype highly ridged, but on all other specimens examined costae are low and rounded, covered
with small granules. Ci on convex thecal edge of holotype, as well as other specimens reported, ridged, bearing
4 or 5 prominent spines. Corallum white.
Septa of holotype and one specimen from the DEKI (between Neira and Lontor) hexamerally arranged in 4
cycles (Si>S2>S3>S4, 48 septa); however, in remaining 10 specimens reported herein the symmetry is decameral:
10:10:20, 40 septa. S1-2 (or 10 primary septa) highly exsert as much as 2.8 mm, forming rectangular lancets with
their adjacent S4 (or tertiaries). Inner edges of S immoderately sinuous. S3 (or secondaries) about 1/2 width of S 1-2,
having very sinuous inner edges. S4 (or tertiaries) 1/3 to 1/2 width of the S3, having moderately sinuous inner
edges. 12 (10 in the case of the decameral specimens) lamellar, highly sinuous pali occur in a crown before the S3
(or secondaries). Fossa of moderate depth containing a fascicular columella composed of 3-7 twisted elements.
Remarks. — As noted in the description, the holotype differs from all other specimens herein reported by
having distinctly ridged C1-2, but this is considered to be a variable character and thus within the range of variation
for the species. More disconcerting is the difference between the hexameral symmetry of the holotype and the
decameral symmetry of most of the other specimens reported. The decamerally symmetrical specimens may
represent a different species, but more specimens of both forms (especially the hexameral form) will have to be
studied to resolve this problem.
Caryophyllia (A.) dentata is similar to C. (A.) grayi, but distinguished by having spines on only one thecal
edge, having a smaller corallum, and having fewer septa (40-48 vs 56).

specimen (Musorstom 2 stn 1) of GCD 20.4 mm has 52 septa and 14 pali. All other specimens examined have
48 septa and 12 pali. Many specimens originally attached to a small, conically-shaped bryozoan colony. The
coraHum is straight, compressed (GCD:LCD = 1 .3-1.4), and has ridged Ct-2. 2 to 4 pairs of elongate, spatulate
thecal edge spines occur on each corallum, the 4th pair present only on the largest coralla. In 1 5-20% of the coralla
examined, additional spines are also present on the lateral faces of the corallum, corresponding to each of the
ateral Ci. When present, the lateral thecal spines originate at a height intermediate between the 2nd and 3rd edge
spines. n rare cases, a 2nd set of lateral thecal spines may occur above the 1 st. Lateral thecal spines very irregular

Type Locality. — "Challenger" stn 210: 9°26'N, 123°34'E (off Negros, Philippines), 686 m.
DESCRIPTION. — Corallum compressed (GCD:LCD = 1.28-1.67) and often slightly curved up to 45° in plane
of LCD. Angle of lateral edges 45°-76°; angle of thecal faces 22°-50°. Largest known specimen ("Albatross"
stn 5256) 14.1 x 19.6 mm in calicular diameter and 25.5 mm in height. Pedicel small (1.8-2. 5 mm in diameter),
unattached as an adult, and circular to elongate in cross section. Convex thecal faces meet in sharp thecal edges,
which are carinate from about 4 mm above base to calicular edge. Delicate edge crests, best preserved in small
coralla, up to 1.9 mm in height, sometimes convoluted and frilled, and occasionally notched with thin
discontinuities. This delicate structure usually reduced to a low, continuous ridge in larger coralla. Remaining Ci-2
on lateral faces highly ridged, up to 0.8 mm in height. Higher cycle costae (C3-4) low and convex, covered with
small, rounded granules. Corallum reddish-brown, the colour usually well preserved only near calice or on small
specimens, the theca of larger coralla often discoloured or partly black.
Septa usually hexamerally arranged in 4 complete cycles (Si-2>S4>S3), with 12 pali, but large coralla may
have 14 primary septa and 14 pali (56 septa), and coralla were also noted with 1 1 and 13 primary septa (44 and
52 septa, respectively). S1-2 highly exsert, having straight to slightly sinuous inner edges that extend 4/5 distance
to columella. S3 least exsert (1.1-1. 3 mm) and least wide septa (about 2/3 width of an Si -2), with sinuous inner
edges, each bordered by a slightly sinuous, lamellar P3 1.5- 1.7 mm in width. S4 about 2.2 mm exsert, fusing to
their adjacent Si or S2 in rectangular lancets. S4 equal to or slightly wider than S3, having slightly sinuous inner
edges. S4, especially of small coralla, spaced slightly closer to their adjacent Si or S2 than to their adjacent S3,
appearing to be angled inward toward their adjacent S3. Fossa relatively shallow, containing the palar crown
(12 P3) and a linear-fascicular columella composed of 7-20 closely-spaced twisted elements arranged in 1 or
2 rows.
Remarks. — As Moseley (1881) suggested and as followed herein, even though A. spinicarens bears thecal
edge crests instead of spines, it is similar to Cary’ophyllia (A.) grayi and was therefore placed in the same subgenus
(but see alternate opinion in discussion of C. (A.) grayi). C. (A.) spinicarens also differs from C. grayi in having:
S4-S3; highly exsert calicular lancets; and ridged Ci-2. It is more similar to C. zanzibarensis Zou, i984, known
only from Tanzania at 238-302 m (Cairns & Keller, 1993), differing only in having a less compressed corallum
(GCD:LCD of C. spinicarens , 1.28-1.67; C. zanzibarensis , 1.77-2.10).

Type Locality. — Karubar stn 58: 8°22'S, 132°01'E (southeast of Tanimbar Islands), 457-461 m.
Etymology. — This species is named for the Karubar expedition.
Description. — Corallum compressed (GCD:LCD = 1.26-/. 36- 1.50) and usually slightly curved in plane of
LCD, but rarely more than 45°. Angle of lateral thecal edges 50°-61°; angle of thecal faces 38°-41°. One of the
larger specimens (the holotype) is 18.8 x 25.3 mm in calicular diameter and 24.5 mm in height. Pedicel small
(1.1 -1.6 mm in diameter), circular, and always unattached as an adult; 6 protosepta usually can be seen on the basal
disc. Thecal faces meet in sharply defined, carinate edges, but edge crests only 1.0- 1.7 mm in height, usually
discontinuous, and less developed on one side. Costae 0.8- 1.0 mm wide, slightly convex in shape, and separated by
narrow, shallow striae; every costa covered with low, rounded granules — 3 or 4 across the width of a costa.
Primary costae slightly more prominent than others, but no costae are ridged. Theca of proximal 4/5 of corallum
worn and white in colour, whereas uppermost theca adjacent to calice usually light reddish brown.
Septa of most specimens (GCD = 12-25 mm) 56 in number, arranged in 3 size classes and 14 sectors:
i.e., 14:14:28, and 24 pali; but, several of the larger specimens have 1 or 2 extra pairs of tertiary septa, resulting
in 58 or 60 septa and 15 or 16 pali. Primary septa highly exsert (up to 5 mm), having sinuous inner edges that
extend to the columella. Secondary septa only 2. 1-2.2 mm exsert, 2/3 width of a primary, also having sinuous
inner edges. Tertiary septa highly exsert (3. 5-3. 9 mm), each pair fused to its adjacent primary septum in a
prominent calicular lancet that produce a highly serrate margin. Tertiary septa about 4/5 width of a secondary,
having straight to only slightly sinuous inner edges. A ring of broad (up to 2.6 mm), sinuous pali occurs before
the secondary septa. Fossa shallow, containing a fascicular columella consisting of 1 or 2 parallel rows of large,
twisted elements.
Remarks. — Caryophyllia karubarica is most similar to C. spinicarens, but differs in having: convex
(rounded, not ridged) primary costae; less prominent edge crests; 14 primary septa, instead of a tendency toward 12
as in C. spinicarens ; a "fuller" corallum (i.e., a lower GCD:LCD), especially in lower half of corallum; and S4
that are less wide than the S3. Caryophyllia karubarica differs from C. unicristata sp. nov. in having a larger, less
curved corallum; 14 primary septa, instead of exclusively 12; two carinate thecal edges, instead of a ridge only on
the convex thecal edge; and more pronounced calicular lancets. These 2 species co-occur at 3 Karubar stations.

Type Locality. — Karubar stn 76: 8°49'S, 131°36'E (south of Tanimbar Islands), 400 m.
ETYMOLOGY. — The species name unicristata (Latin unus, one + crista , crest) refers to the single edge crest of
this species.
DESCRIPTION. — Corallum relatively small, the largest specimen (KARUBAR stn 39) only 15.5 mm in GCD;
the holotype is 10.9 x 13.4 mm in calicular diameter and 16.0 mm in height. Corallum ceratoid, regularly curved
45°-90° usually in plane of GCD. Pedicel small (0.8-0.9 mm in diameter), unattached, and not reinforced. Calice
elliptical: GCD:LCD = 1.21-1.32. Base of pedicel often free, detached from substratum, its flat lower side
revealing the 6 protosepta; sometimes worn to a rounded tip; or occasionally overgrown by a bryozoan colony.
A low (0.9- 1.1 mm), sinuous crest occurs on convex edge of each corallum, the concave edge being evenly
rounded. Convex edge crest best developed in small coralla, often worn or lost in larger coralla. The other 1 1 Ci-2
are raised and slightly rounded (not ridged); C3-4 flat. All costae covered with low, rounded granules, 3 or 4 across
width of a costa. Upper 1-2 mm of theca and adjacent septa reddish-brown; remainder of corallum white.
Septa hexamerally arranged in 4 complete cycles: Si-2>S3>S4, and 12 pali. S 1-2 about 1.5 mm exsert, having
vertical, slightly sinuous inner edges that almost attain the columella. S3 about 0.4 mm exsert and 2/3 width of
the Si -2, having highly sinuous inner edges. S4 intermediate in exsertness, each pair of S4 fusing to its common
Si or S2 to form a low calicular lancet. S4 equal to or slightly less wide than S3, the widest S4 occurring in coralla
of greatest size. Inner edges of S4 slightly sinuous. 12 prominent P3 1.2- 1.4 mm wide, with sinuous edges.
Columella consists of 4-12 well-formed, twisted elements, 4-6 arranged in a line or a larger number in 2 parallel
rows.
Remarks. — Within the subgenus Acanthocyathus, A. unicristata needs to be compared only to the 3 species
that have ridged (nonspinose) thecal edges: C. spinicarens , C. zanzibarensis , and C. karubarica , from which it
differs in having: only one carinate thecal edge (on its convex side); a more circular calice (a relatively low
GCD:LCD of 1.21-1.32); a smaller pedicel diameter; consistently hexameral symmetry; and low calicular lancets.
Distribution. — Indonesia : Arafura Sea (southeast of Tanimbar Islands); 251-477 m.

irregular scar 1.0- 1.5 mm in diameter. Only one specimen (Karubar stn 15) was found bearing an opposite bud at
this level, instead of having an open base. In fact, the usually open base is probably the result of breaking apart of
parent or opposite bud. Septal symmetry quite variable. Of the 57 septal/palar permutations inferred by MORI
(1987), the 4 well-preserved Philippine specimens displayed the following symmetries: 8/8/16, 8 (1 specimen),
10/10/20, 10 (1 specimen), and 10/10/18, 9 (2 specimens), which were the 13th, 4th, and 5th most common
arrangements, respectively, among specimens MORI examined from the type locality. Primary and secondary septa
and all pali have sinuous inner edges. Pali occur before secondary septa. Fascicular columella composed of
1-4 twisted elements.
REMARKS. — The holotype of Placotrochides dentiformis (ZMA Coel. 1093) is a poorly preserved specimen
4.2 x 6.9 mm in calicular diameter and 7.4 mm in height, having a septal complement of 8:8:10 (26 septa). This
septal arrangement is shared with only 7 of the 1090 specimens analyzed by MORI (1987). Due to poor preserva¬
tion, no pali are present, but a fascicular columella composed of twisted elements is recognizable. Although a poor
specimen, there is little doubt that it is conspeciftc with the species later reported as Premocyathus compressus.
Coralla of Trochocyathus apertus sp. nov. are similar in shape and size to P. dentiformis but differ in having a
papillose columella, P|-3 (not just P3), and in having a less compressed corallum.
Cairns & Keller (1993) and Cairns (1995) previously considered there to be 5 species in the subgenus
Caryophyllia (Premocyathus), but we now place 2 of them, Acantkocyathus spinicarens (Moseley, 1881) and
C. zanzibarensis Zou, 1984, in the subgenus Caryophyllia (Acanthocyathus)\ and the other 2, C. (Premocyathus)
burchae Cairns, 1984, and C. (P.) compressa sensu Wells (1956) (= Trochocyathus apertus sp. nov.) are herein
transferred to Trochocyathus. Only 1 species remains in Premocyathus, P. dentiformis. The genus Premocyathus is
thus defined as having: a curved, laterally compressed corallum with a carinate convex edge and an open base that
most likely is the result of separation from an opposite budded specimen; a variable septal symmetry; pali before
the penultimate septal cycle; and a fascicular columella.

hexamerally arranged in 5 cycles (Si-2>S3>S4>Ss), the 4th cycle (48 septa stage) attained at a GCD of 7-9 mm.
Inner edges of Si -2 moderately sinuous. Fossa deep; pali absent; fascicular columella composed of numerous (15-
20), slender, twisted elements.
Remarks. — Crispatotrochus rubescens is more fully described and illustrated by Cairns (1994). Cyathoceras
tydemani is a juvenile specimen of C. rubescens , collected at a stage transitional between the 4th and 5th septal

Remarks. — Crispatotrochus rugosus was recently described based on specimens from the New Zealand
region; only a single, worn specimen of 8.7 mm GCD is reported herein. It is distinguished from C. rubescens by
having fine, transverse thecal ridges, and Si that are wider than S2. Fragments of a much larger specimen
(MUSORSTOM 2 stn 32, MNHN) — having an estimated GCD of 32 mm, 5 cycles of septa, and transverse thecal
costal ridges — may represent a large specimen of this species. Unfortunately, that specimen is missing its pedicel
and columellar region.

Diagnosis. — Corallum trochoid, firmly attached through a robust pedicel (PD:GCD = 0.1 1-0.41), up to
21 mm in GCD. Costae broad, flat to slightly convex, and covered with low, rounded granules. Corallum white to
light brown. Septal symmetry appears to change with size. Coralla 8-12 mm in GCD have 4 cycles of
48 hexamerally arranged septa (Si-2>S3>S4). Larger coralla over 16 mm GCD often have 16 primary septa and
3 size classes of septa, resulting in 64 septa, or hexameral symmetry but with an incomplete 4th cycle, also
resulting in 64 septa (MUSORSTOM 1 stn 63). Discrete pali arranged in 2 or 3 crowns before all but last cycle of
septa. Columella composed of an elliptical field on numerous (up to 45), slender rod-shaped papillae.
Remarks. — One aberrant specimen (Musorstom 2 stn 32) has undergone intratentacular budding, resulting
in a small colony of 3 massive corallites, each the result of equal, intratentacular division. T. caryophylloides is
more fully described and figured by Cairns (1994).
In our opinion, the species name was originally incorrectly formed, being derived from the root Caryophyllia ,
and thus should be caryophyllioides. However, according to the ICZN (Article 32dii) the original spelling cannot
be changed.

DIAGNOSIS. - Corallum elongate-conical, straight, Oared distally, and attached by a broad pedicel 0.60-0.80
CCD. Pedicel increases in diameter by formation of thin exothecal dissepiments over raised basal costae, similar to
the process in Rhizosmilia. Largest Philippine specimen 8.6 x 10.3 mm in calicular diameter and 9.7 mm in
height; largest known specimen (CAIRNS, 1995) 13.8 mm in GCD. Costae granular, well-defined only in upper
part of corallum. Corallum white, but theca and all septa (not pali) speckled with dark brown-black pigmentation.
Septa hexamerally arranged in 5 cycles, the 5th never complete. The large Philippine specimen has only 1 pair of
S5 (50 septa) and a New Zealand specimen has as many as 64 septa. Si highly exsert, forming calicular lancets.
S2 smaller than Si but larger than S3. S4 variable in width, those adjacent to Si often wider than the S3, those
adjacent to S2 usually less wide than S3. Two crowns of pali present: 12 small Pi-2 occurring low in the fossa,
and 12 larger P3 rising much higher in fossa. P4 present on septa flanked by a pair of S5. Papillose columella a
field of 20-30 fine pillars.
Remarks. — Trochocyathus maculatus is more fully described and illustrated in the original account. It is
distinguished from its congeners by its distinctively speckled corallum and exothecal dissepiments.

DESCRIPTION. — Corallum ceratoid to trochoid and relatively small, the largest corallum (MUSORSTOM 3
stn 88) 12.3 x 17.6 mm in calicular diameter and 26.4 mm in height, but most specimens less than half this size;
one syntype measures 9.5 x 11.0 mm in calicular diameter and 19 mm in height (fide SEMPER, 1872). Calice
elliptical : GCD:LCD = 1.15-1.64. Coralla often maintain their attachment to substratum through a robust pedicel
2. 9-6.7 mm in diameter (PD:GCD = 0.20-0.44), the substratum often consisting of a small gastropod shell, an
echinoid spine, a pebble, or a corallum of a dead Scleractinia such as Flabellum or Balanophyllia. Corallum
usually straight, occasionally bent near base. About 1/3 of specimens examined bear slender thecal edge spines, the
remaining coralla having evenly rounded thecal edges. Of those having edge spines, size and symmetry are quite
variable. Some specimens have a pair of spines, but coralla bearing a single spine or just a nub or low crest on
one thecal edge are not uncommon. Only one specimen (MUSORSTOM 3 stn 96) has 3 spines: 2 on one edge and
1 on the other. Lower 1/3 to 1/2 of theca white and porcellaneous; however, upper 1/2 to 2/3 dark brown, bearing
well-formed, convex costae separated by deep intercostal furrows. Costae in upper corallum with minute granules.
Septa hexamerally arranged in 4 full cycles: Si-2>S3>S4I however, some large specimens have 1 or 2 pairs of
Ss resulting in 50-52 septa, and small coralla less than 9 mm GCD often lack several pairs of S4. S1-2 about
1.7 mm exsert, having vertical, slightly sinuous inner edges, each bordered by a small (0.3-0.5 mm) papillose to
lamellar palus. S3 about 1.3 mm exsert, with slightly more sinuous inner edges, and bordered by lamellar P3.
P3 each about 1.0 mm wide and forming a crown that rises higher in the fossa than the crown of P1-2. S4 equally
exsert as S3, in small to medium-sized coralla S4 slightly less wide than the S3, but S4 become proportionately
wider with growth of the corallum, until they sometimes slightly exceed the S3 in width. Fossa of moderate depth,
containing a papillose columella consisting of 6-20 interconnected papillae.
Remarks. — Among the 23 Recent species in the nominate subgenus of Trochocyathus, only 2 other have
thecal edge spines: T. semperi sp. nov. and T. cooperi (Gardiner, 1905). T. philippinensis is distinguished from
T. semperi by having: a larger corallum with a more robust pedicel (2.9-6.7 mm in diameter vs 1.7- 1.9 mm for
T. semperi ); hexameral septal symmetry resulting in 48 septa (not 40 septa); asymmetrical and erratic
development of thecal edge spines (vs usually two pairs for T. semperi)- and highest cycle septa (S4) that are
sometimes as large as the penultimate cycle (S3), whereas the tertiary septa of T. semperi are 1/2 the width of
their secondaries. Furthermore, T. philippinensis is more common in deeper water than T. semperi, i. e. , 1 GO-
268 m whereas most records of T. semperi are from less than 1 00 m.
Although similar in calicular features, T. cooperi differs from T. philippinensis by dividing transversely (basal
scar), and in having plate-like, lamellar thecal edge spines.

TYPE LOCALITY. - Corindon 2 stn 251: 0°53.7'S, 1 19°29.6'E (Makassar Strait), 65 m.
ETYMOLOGY. - This species named for Carl Gottfried SEMPER, in recognition of his work on shallow water
azooxanthellate corals of the Philippine region (see Semper, 1872).
DESCRIPTION - Corallum ceratoid and relatively small, most specimens examined only 5-7 mm in GCD and

Holotype 4 9 x 6.6 mm in calicular diameter and 8.4 mm in height. Calice elliptical. GCD. LCD - 1.25-1.37
Colalla often maintain their attachment to substratum through a robust pedicel 1.7- 1.9 mm >" diameter
(PD GCD = 0 18-0 30), the substratum often being a bivalve shell, large foramimferan, or other corals, sue
Heteropsammia. Pedicel next to basal disc often bent 30°-45°. Occasionally corallum detached from the substratum
revealing the basal disc and original 6-12 protosepta. Most coralla bear at least 2 pairs of delicate thecal
edge spines, the 1st pair beginning its development almost immediately above the basal disc as an ^tension of
thf 2 principal CSi; in 2 cases the lowermost spines were fused to the substratum Edge spines spatulate
proximalW cylindrical distally, and up to 3.6 mm in length, but. because of their delicate nature, only small
coralla be^ intact, elongate spines. All costae equally convex and granular. Upper 1/2 of theca blackish-brown,
lower 1/2 of theca and calicular elements white. „ , , ,
In early development, septa are hexamerally arranged in 3 cycles, but by a GCD of about ^ mm a decamer^
symmetry is adopted, adult coralla usually having 3 size classes of decamerally arranged septa (40 septa . Pnmary
septa 0.8 1.0 mm exsert, having vertical, slightly sinuous inner edges, each bordered by a small, Pooriy-formed

Fossa o7moderate depth, containing a papillose columella composed of 5-9 slender elements, sometimes
indistinguishable in size and shape from the Pi.
Remarks - Only 3 of the approximately 23 Recent species of Trochocyathus (Trochocyathus) have thecal
edge spines: T. cooped (Gardiner, 1905); T. semperi ; and T. philippinensis , the last 2 species being compared
the previous account. Within the Scleractinia, edge spines are often associated with coralla i of th®[
transversely divide as a method of asexual propagation (e.g., Trochocyathus most spec es of
Truncatoflabellum)', however, in both T. philippinensis and T. semperi , no specimens show evidence of
division, many displaying their original basal disc.

Description. — Corallum relatively small, usually curved about 90° in plane of GCD, and somewhat
compressed (GCD:LCD = 1.19-1.37). Largest known specimen (ZMUC) 7.2 x 9.9 mm in calicular diameter anc

S. D. CAIRNS & H. ZIBROWIUS
14.3 mm in height; holotype 7.9 x 6.3 mm in calicular diameter and 11.8 mm in height. All coralla examined
unattached (free), with an open base 1.2-1. 8 mm in diameter that reveals the 12 septa: 6 thick and 6 thin. Each
corallum bears a short thecal edge crest on its lower convex edge, up to 5 mm long, up to 3 mm in height, and
about 0.5 mm thick. Crests best developed on small coralla, becoming worn or broken with age, not extending to
calicular edge. Crests absent from concave thecal edge, but occasionally the principal Ci of the concave edge is
slightly prominent or thickened. Costae low, convex, granular ridges separated by broad, shallow intercostal
furrows. Corallum white.
Septa hexamerally arranged in 4 cycles, but 4th cycle never complete. The most common septal complement is
40, arranged: 12:12:16, with 4 half-systems lacking pairs of S4 (e.g., the holotype). If the 12 half-systems are
numbered in a clockwise direction, starting with the half-system to the right of the principal septum aligned with
the convex edge, the 4 half-systems that lack S4 pairs are usually the 3rd, 5th, 8th, and 10th. Coralla having
44 septa, the largest number of septa observed, usually lack S4 pairs in the 5th and 8th half-systems. Si -2 up to
1.3 mm exsert, having vertical, slightly sinuous inner edges. S3 about 1.0 mm exsert, with slightly sinuous inner
edges, about 3/4 the width of an S2- S4 slightly less exsert and 3/4 width of an S3. Most, but not all, S1-2 bear a
small (0.3-0. 5 mm wide) papillose to lamellar palus, the papillae being indistinguishable from columellar
elements, except that they rise higher in the fossa. P3 always lamellar, about 1 mm wide, with straight edges, and
rising even higher in the fossa. The fossa contains a papillose columella consisting of 7-10 interconnected pillars,
each about 0.3 mm in diameter.
Remarks. — Cairns (1984) previously considered this species to be Premocyathus compressus
(= Premocyathus dentiformis herein) because of their similarity in corallum size and shape; because both species
have open bases; and because many specimens of T. apertus lacked Pi -2 and thus resembled a Caryophyllia ground
plan. In spite of these convergent characters, T. apertus differs significantly in having a papillose columella
composed of slender rods (not a fascicular composed of twisted lamellae), and in having often distinct Pi -2.
Furthermore, whereas the septal symmetry of P. dentiformis [= C. (P.) compressa sensu MORI, 1987] is quite
variable, the hexameral pattern that is most common in T. apertus (12:12:16) is quite rare (0.3%) in
P. dentiformis. Overall hexameral symmetry is the rule in T. apertus , but rare (only 3%) in P. dentiformis.

Diagnosis/Remarks. — Little can be added to the original description based on Hawaiian specimens.
Although quite similar, T. burchae differs from T. apertus in having a smaller corallum with a smaller open base;
a brown-black pigmented upper theca; and a more distinctly developed thecal edge crest. The crest of the convex
side of T. burchae is up to 4.8 mm in height and usually continuous from base to calice, occasionally bilobate.
Furthermore, some coralla have a low crest on the lower concave thecal edge. The largest known specimen
(MORTENSEN stn 9) is 6.4 x 10.0 mm in calicular diameter.
Trochocyathus burchae is placed in this genus for the same reasons cited for T. apertus: its papillose columella
and the occasional presence of Pi-2 as well as P3.

DIAGNOSIS. - Corallum (anthocyathus) compressed (GCD:LCD = 1.4-2.3). Angle of thecal edges, not
including crests, 19°-30°; angle of thecal faces, 20°-25°. One of the largest known specimens ( ^Watross
stn 5202) 12.1 x 17.3 mm in calicular diameter and 17.7 mm in height, whereas another, rejuvenescent coraUum
(MUSORSTOM 1 stn 57) is 15.9 x 17.6 mm in calicular diameter and 26.9 mm in height. Basal scar elliptical, up
to 4 0 mm in greater diameter. Base of each thecal edge bears a large (up to 4.5 mm), downward-projecting crest,
sometimes recurved toward the basal scar. Corallum reddish-brown, often with a more intense costal striping and/or
costal speckling near the calice. Septa hexamerally arranged in 4 full cycles (Sl-2>S3>S4). L^ge coral a may have
some additional pairs of S5 up to a total of 56-62 septa. Two crowns of pah occur, 12 small Pl-2 and 12 larger P3.
Papillose columella composed of 10-30 slender, cylindrical elements. , .
Anthocaulus stage rarely collected, attaining up to 6 mm in height, 7.7 mm in GCD, and having a robust
pedicel diameter of 3.4 mm. It may have 4 complete cycles of septa (Si-2>S3>S4) and prominent edge crests.
REMARKS. - Trochocyathus cooperi is one of 4 species in the subgenus that divides transversely. The other
3 species [T. gardineri (Vaughan, 1907); T. cepulla Cairns, 1995; and T. discus sp. nov.] are disco, dal (bowl¬
shaped), nonspinose, and nonnested. T. cooperi is more fully described and illustrated by CAIRNS ( 1994)
The description of Trochocyathus weberi Alcock, 1902a fits that of T. cooperi , except for the co our of .ts
corallum, which was stated to be "snow white". T. weberi was one of 8 species described by ALCOCK (1902a) in
his prelim, nary "Siboga" report but not included in his final report (ALCOCK, 1902c). It was never illustrated, a
station number was never cited, and it could not be found in the collections of the ZMA in 1994. Therefore, its
equivalence with T. cooperi remains questioned.

ETYMOLOGY. — The species name brevispina (Latin brevis , short + spina, spine) refers to the 6 short Ci
spines.
Description. — Corallum bowl-shaped and free, the base flat to evenly rounded, often with a imprint of
original substratum attachment or even an incorporated fragment of substratum at centre ot base. Holotype 20.3 x
22.1 mm in calicular diameter and 9.3 mm in height, containing 66 septa; largest specimen (Karubar stn 3)
22.3 x 26.1 mm in calicular diameter and 12.8 mm in height, containing 72 septa. Calice elliptical. GCD.LCD -
1.07-1.17. Costae well defined only near calice, where they are slightly convex and granular; remainder of base
usually worn and/or smooth, often with a hexagonal region of epitheca bounded by the 6 costal spines. All
specimens examined bear 6 short (not more than 5 mm in length) costal spines associated with the Ci, the spines
of some coralla being strongly compressed and ridged basally, these ridges extending to the centre of the base.
Well-preserved coralla black-brown in colour.
Septa hexamerally arranged in 5 cycles, several pairs of S5 present already in small coralla ol 12 mm GCD, but
even in large specimens 5th cycle never complete, the largest corallum having only 12 pairs of S5, or a total of
72 septa. Septal formula: Si-2>S4>S3>S5. Si-2 are 3.5-4.0 mm exsert, robust, having thick, straight inner edges
bordered by a well-defined palus. S3 slightly less exsert (2.5 mm) and about 3/4 width of an Si -2, each S3 also
bordered by a palus of equivalent size to a P1-2 but recessed slightly from the columella. S4 of equal exsertness to
S3, but slightly wider than S3, unless flanked by a pair of S5, in which case the S4 are narrower than an S3.
S4 flanked by S5 bear a palus of similar size to the others, but recessed even more from the columella than the P3.
When present, S5 are least exsert and least wide class of septa. All pali (Pi-4) thick, about 1.5 mm wide, having
straight, vertical inner edges; pali separated from their bordering septa by narrow (about 0.8 mm), deep notches.
Fossa shallow, containing a papillose columella composed of 9-20 small, irregularly-shaped pillars.
Remarks. — Three Recent species are now attributed to the subgenus Aplocyathus. Trochocyathus brevispina
differs from T. hastatus Bourne, 1903 (Figs 13 a-c), in always having 6 short costal spines, not 5 elongate ones. It
also differs in: having a larger corallum with more septa, the maximum known size of T. hastatus is 18 mm GCD
with 48 septa; having Si=S2, T. hastatus having S i>S2; and having equal-sized Pi-4, those ol T. hastatus being
unequal in size. T. brevispina is compared to T. longispina in the account of that species (see below).

Type Locality. — Musorstom 1 stn 50: 13°49'N, 120°01'E (Lubang Island, Luzon), 415-510 m.
ETYMOLOGY. — The species name longispina (Latin longus, long + spina, spine) refers to the 6 elongate Ci
spines.
DESCRIPTION. — Corallum bowl-shaped and free, the base flat to slightly convex, often maintaining the scar of
original attachment. At a diameter of 9-1 1 mm the horizontal base is sharply inflected upward at 65-70°. Largest
specimen (holotype) 17.0 mm in calicular diameter and 12.7 mm in height. Calice circular. Costae well defined
only near calicular edge, otherwise lower theca and base uniformly granular. Six slender, elongate (up to 10 mm)
costal spines (Ci) project horizontally from the outer edge of base; spines circular in cross section. Corallum
white.
Septa hexamerally arranged in 4 complete cycles in all specimens reported (Si-2>S3>S4). Each Si -2 up to
3.0 mm exsert, with a slightly sinuous inner edge, bearing a small palus 0.5- 1.0 mm in width that contributes to
a crown of 12 Pi-2 located close to the columella. S3 less exsert (about 1.7 mm) and about 2/3 width of Si-2,
having moderately sinuous inner edges. Each S3 bordered by a large, lamellar P3 about 2.0 mm wide, the 12 P3
forming a crown that rises higher in the fossa and is slightly more recessed than the P1-2 crown. S4 about 0.8 mm
exsert, 1/2 the width of S3, without lobes. Fossa shallow, containing a prominent columella consisting of
irregularly-shaped papillae.
Remarks. — Trochocyathus longispina differs from T. brevispina sp. nov. in having a smaller corallum, less
septa, a circular (not elliptical) calice, a white (not black-brown) corallum, and longer costal spines that are circular
(not flattened) in cross section. T. hastatus Bourne, 1903 (Figs 13 a-c), the other Recent species in the subgenus,
differs from T. longispina in having S i>S2, a porcellaneous base, a brown-black corallum, and only 5 costal
spines. T. longispina also resembles Stephanocyathus (Acinocyathus) explanans (Marenzeller, 1904), both species
having 6 long costal spines, a white corallum, and a similar palar arrangement, but differs in having a smaller
corallum and correspondingly less septa and pali (48 vs 72 septa), and sinuous inner septal edges, especially
of the S3. The inner septal edges of S. explanans are straight, which is one of the few characters that differentiate
the subgenera Stephanocyathus (Acinocyathus) and Trochocyathus (Aplocyathus).

hexamerally arranged in 4 complete cycles: Si>S2>S4>S3, the Si usually quite thick and "swollen" appearing.
Three crowns of thick, ridged pali (Pi, P2, and P3), arranged in typical trochocyathid fashion. Columella of
moderate depth; papillose columella composed of 3-40 tuberculate pillars.
REMARKS. — Two specimens from MUSORSTOM 3 stn 108 show evidence of having been bored by an
acrothoracican cirripede crustacean, which is not uncommon in this genus (ZlBROWlUS, 1980; CAIRNS, 1995).

TYPE Locality. — 19°48’N, 154°58'W (Hawaiian Islands), 337 m.
Diagnosis/Remarks. — This species was redescribed and illustrated by Cairns (1995) based on specimens
from ridges north of New Zealand. Six additional specimens from 3 stations are reported above. The anthocyathus
is relatively small (usually less than 6 mm GCD), discoidal to cylindrical corallum with a basal scar resulting
from transverse division. Each Ci bears a prominent costal spine. Septa are hexamerally arranged in 4 cycles, the
4th incomplete, usually resulting in 36 septa. Pali occur before all but the last cycle of septa and the columella is
papillose.
As previously discussed in this paper, at least 4 Recent species of Trochocyathus reproduce by transverse
division, and 5 species bear costal spines, which are present as edge spines in 3 species and as 5-1 1 C1-2 spines in
another 2 [i.e., Trochocyathus (Aplocyathus)]. One species, T. cooperi (Gardiner, 1905), has both edge spines and
transverse division, but no species of Trochocyathus has the character combination of transverse division and 6 Ci
spines, as does Bourneotrochus stellulatus. Nevertheless, a strong relationship to Trochocyathus is suggested,
perhaps even at the subgeneric level.

covered with low, rounded granules — approximately 3 granules occurring across width of a costa. Septa, paliform
lobes, and columella pigmented a dark brown, purple-grey, blue, or blackish-brown. Theca usually white, but
occasionally also darkly pigmented at calicular edge.
Septa hexamerally arranged in 5 cycles, the last cycle never complete. Largest specimen with 84 septa
(5th cycle lacking 6 pairs of septa); a specimen 7.5 mm GCD with 66 septa. Si-2 about 1 mm exsert, having
vertical, straight inner edges that bear 1-3 paliform lobes, the uppermost lobe occurring about 1/2 distance to
columella. S3 only slightly less exsert than S1-2, each bearing 3-5 narrow paliform lobes, the uppermost lobe
reaching slightly higher than the P1-2. S4 less exsert and less wide than S3, their narrow paliform lobes mingling
with those of S3 low in fossa. S5 smallest septa, their paliform lobes fusing with those of S4 in a complex
tuberculate region. Fossa relatively deep. Columella trabecular to papillose, concave, and indistinguishable from
lowermost paliform lobes of all septa (nondiscrete).

TYPE Locality. — "Hakuho Maru" stn KH72-1-26: 9°27'S, 127°58.6'E (Timor Sea, south of Leti Islands),
610-690 m.
ETYMOLOGY. — The shape of the corallum in this genus occasionally has been compared to a crown. This
theme is reiterated here (Latin regius, royal).
DESCRIPTION. — Corallum bowl-shaped, with a flat to slightly convex base. Holotype 29.0 mm in calicular
diameter and 12.5 mm in height; largest specimen ("Hakuho Maru" stn KH72-1-26) 32 mm in calicular diameter
and 11.5 mm in height. Centre of base often displays an irregularly-shaped imprint of detachment from
substratum; otherwise, base covered with low, convex, coarsely granular ridges, the Ci-2 sometimes slightly more
prominent than others. Corallum uniformly white.
Septa hexamerally arranged in 5 full cycles (Si>S2>S3>S4>Ss), some specimens as small as 18 mm GCD
having a full 5th cycle, whereas other larger specimens (e.g., 25-32 mm GCD) may lack several pairs of S5,
resulting in 86-94 septa. Si highly exsert (3. 9-4. 2 mm), having straight inner edges, each Si internally bordered
by a broad (up to 2.2 mm) notch and 2 or 3 paliform lobes, each lobe decreasing in size toward columella. S2
virtually the same as Si, but sometimes slightly less exsert. S3 less exsert (about 3.3 mm), only about 4/5 width
of an Si or S2, each S3 bordered by a narrow notch and 1-4 paliform lobes, the outermost lobe sometimes quite
wide (2.0 mm). Outermost lobes of P3 crown always stand higher in fossa than those of Pi -2 and are
more recessed from the columella. S4 less exsert (about 2.5 mm), about 4/5 width of an S3, with slightly sinuous
edges, and bordered by 3 or 4 paliform lobes, the outermost lobe being the largest and occurring higher in the fossa
and farther from the columella than P3. Innermost P4 often fuse with their common P3 near columella. S5 least
exsert septa (about 1.5 mm), with slightly sinuous inner edges, becoming rudimentary lower in fossa, bearing no
paliform lobes. Thus, only the Si and S5 are independent septa, the inner edges of the Pi reaching the columella
and those of the S5 diminishing in size, whereas the inner P3 merge with their common P2 and the inner P4
with their common P3. Fossa shallow, containing an elliptical field of 20-30 small densely fused papillae, the
innermost Pi -4 being indistinguishable in size and shape from the columellar elements.
Remarks. — Among the 7 species in the nominate subgenus, S. regius most closely resembles S. paliferus
Cairns, 1977 (known only from the western Atlantic at 229-715 m), both species having a similarly-shaped
corallum and well-developed paliform lobes. S. regius differs in having multiple paliform lobes and in lacking
small costal spines on the C1-2. S. regius also resembles Vaughanella multipalifera Cairns, 1995 in most
-haracters but differs in having an unattached corallum.

S. D. CAIRNS & H. ZIBROWIUS
ALCOCK (1902a) described 2 additional species of Stephanocyathus, each based on a small, worn corallum:
? Sabinotrochus flatiliseptis ("Siboga" stn 211, ZMA Coel. 1315, CD = 11.6 mm, Fig. 14 i) and
? Sabinotrochus bipatella ("Siboga" stn 52, ZMA Coel. 1314, CD = 8.1 mm. Fig. 14 f)- Given their small size
and poor state of preservation, they cannot be confidently identified as one of the better known species of
Stephanocyathus. Although they are illustrated herein, their names are not included in Table 1.

Diagnosis/Remarks. — This common, relatively shallow-water Indo-West Pacific species was redescribed by
Cairns & Parker (1992) and Cairns (1994). It is characterised by having an unattached, bowl-shaped corallum
with 6 long (up to 25 mm), slender costal spines (Ci) that project horizontally from the edge of the base. Septa
hexamerally arranged in 5 cycles (Si»S2>S3>S4>Ss); however 1 large specimen (Karubar stn 86) of 40.6 mm
GCD has 6 additional pairs of S6, 1 S6 on each side of an Si, resulting in 1 10 septa. Largest Philippine specimen
("Albatross" stn 5541) 42 mm in calicular diameter, as measured from outer edge to outer edge of opposing exsert
Si. Si and S2 extremely exsert, each forming a rectangular calicular lancet with its adjacent S5 (or S6). Si, and
occasionally S2, pigmented a dark brown or black. Three crowns of broad paliform lobes (Pi-2, P3, and P4)
present, the Pi -2 often integrated into the columella.

TYPE Locality. — "Valdivia" stns 194, 243, and 245: off Sumatra, Zanzibar Island, and Pemba, 245-614 m.
Description. — Corallum bowl-shaped, with a slightly rounded base, the thecal edges diverging at a 40°-45°
angle. Most coralla 21-27 mm in calicular diameter, the largest known corallum (KARUBAR stn 35) 27 mm in
calicular diameter and 20. 1 mm in height. All specimens bear 6 relatively short, slender, tapered, straight costal
spines (basal diameter 1.5-1. 7 mm) that project horizontally from the Ci at point of upward thecal inflection.
Spines best known from juveniles, where they are up to 9 mm long; in larger (older) coralla, Ci spines are either
broken or reduced to small nubs. In about 1/4 of specimens examined, 1-5 additional costal spines present on C2.
All costal spines circular in cross section. Lower corallum, to a level just above costal spines, usually eroded, as
though submerged in a soft substratum. Theca above this region costate, the costae slightly convex and granular.
Corallum white.
Septa hexamerally arranged in 5 cycles, the 5th cycle never complete: the most common septal complement is
72, achieved by having a pair of S5 in each of the 12 quarter systems adjacent to the 6 Si. S 1-2 about 3.3 mm
exsert, having straight, vertical inner edges, each bordered internally by a deep, broad (up to 1.6 mm) notch and a
rather narrow, lamellar paliform lobe only about 1 mm wide, which is often merged into the columella. S3 about
2 mm exsert, 3/4 width of an Si-2, and bordered by a narrow (about 0.5 mm) notch and a prominent, broad (2.0-
3.5 mm) paliform lobe. S4 that are flanked by S5 almost as wide and exsert as an S3, but bear a narrow paliform
lobe (about 0.9 mm), which is often fused into or subsumed by the P3. Unflanked S4 only 1.5 mm exsert, about
half width of an S3, becoming rudimentary lower in fossa. Because Pi -2 are directly adjacent to the columella, and
P4 are often fused into the P3 or poorly developed, many coralla appear to have only 1 crown of 12 massive P3.
S5 resemble unflanked S4. Inner edges of all septa and paliform lobes straight. Calicular margin serrate, but not
produced into lancets. Fossa relatively shallow. Columella composed of 8-10 granular papillae that are circular in
cross section, which distinguish them from the closely adjacent lamellar Pi-2-
Remarks. — Stephanocyathus explanans differs from the only other Recent species in this subgenus,
S. spiniger, in having a serrate (not lanceted) calicular edge; 48-72 (not 96) septa; 6-11 relatively short costal
spines that are circular in cross section (vs 6 elongate, basally compressed Cl); a completely white corallum;
equal-sized SI and S2; and wider and more developed P3.
Distribution. — Indonesia : Arafura Sea (southeast of Tanimbar Islands); 405-1016 m. Elsewhere: Malaysia
(Celebes Sea off Sabah); South Africa, Madagascar, and Tanzania; west of Sumatra; 183-614 m.

the C3 of those half systems that possess 4 C5. In some specimens, tubercles are replaced by a thickened rim that
encircles the base of the corallum. Corallum white. Septa hexamerally arranged in 5 cycles (Si-2>S3>S4»Ss) —
the 5th cycle never complete, 72 being a common number of septa. Paliform lobes present before all but last
cycle of septa. Columella papillose to lamellar (Fig. 14h), the latter aspect a result of the intermingling of

Genus ERICIOCYATHUS nov.
Type Species. — Ericiocyathus echinatus , here designated.
Diagnosis. — Corallum solitary, bowl-shaped, and free. Septotheca costate, each C1-2 bearing a series of
elongate spines. Pali in a crown before penultimate septal cycle (P3). Columella papillose.
Remarks. — Among the caryophylliid genera, Ericiocyathus is most similar to Stephanocyathus
(Odontocyathus), both taxa having similarly shaped coralla of approximately the same size, and costal tubercles or
spines on their Ci -2. Ericiocyathus differs in having pali associated only with the S3, whereas S. ( Odontocyathus )
has 3 (or 4) cycles of paliform lobes. Also, S. ( Odontocyathus ) has only 12-18 costal tubercles (Ci-2, 3) relegated
to the lower, outer edges of the corallum, whereas Ericiocyathus has a series of elongate spines along each C1-2.
Stephanocyathus (Acinocyathus) and Trochocyathus (Aplocyathus) are also similar to Ericiocyathus in having
elongate costal spines, but differ in having a total of only 5 or 6 spines (one per Ci), and in having Pi -2 in
addition to P3.
ETYMOLOGY. — The genus name Ericiocyathus (Latin ericius, hedgehog + cyathus , cup) refers to the spiny
corallum. Gender: masculine.

ETYMOLOGY. — The species name (Latin echinatus, covered with spines) refers to the many costal spines.
Description. — Corallum bowl-shaped and unattached, the base being evenly rounded and the thecal edge
angle 43°-53°. Small coralla bowl-shaped, but older coralla have high thecal edges, the largest specimen (the
holotype) 18.6 mm in calicular diameter and 16.8 mm in height. Each Ci-2 bears a row of long, tapered costal
spines that project perpendicularly to the theca. These spines are short (eroded) near the base, but on the sides of
the corallum costal spines up to 6.0 mm long with a basal diameter of 1.2 mm. Spines occur approximately every
2 mm, up to 6 aligned on each C1-2; the holotype has at least 60 spines, whereas smaller specimens have fewer.
Costae developed as low, convex, granulated ridges only near calicular edge. Corallum white.
Septa hexamerally arranged in 4 complete cycles (Si-2>S3>S4), septa of the 4th cycle beginning to be present
at a GCD of 5 mm. Si -2 about 3 mm exsert, having straight, vertical inner edges that extend about 2/3 distance to
columella. Si -2 do not have paliform lobes or pali. S3 about half as exsert as and 3/4 width of Si -2, with straight
to only slightly sinuous inner edges. S4 lowest septa, 2/3 width of an S3, having straight inner edges, becoming
rudimentary lower in fossa. A crown of 12 thin, lamellar, planar P3, each 1.5-2. 5 mm wide, encircles a columella
composed of 3-6 papillae or short lamellae. Fossa relatively shallow, the pali rising high in the fossa contrasting
with the columella, which is deeply seated.

479 m.
Etymology. — Named for the region from which it was first collected.
DESCRIPTION. — Corallum bowl-shaped, the largest specimen (holotype) 15.0 mm in calicular diameter and
6.0 mm in height. Centre of base (up to 5-7 mm) usually eroded and discoloured to a chalky white. Beyond central
worn region radiate 24 ridged costae (C1-3), which become prominent near calicular edge. C1-3 covered with very

fine spines, both laterally and apically. C4 ridges present only near calicular edge, also bearing fine, elongate
spines. Intercostal spaces broad and smooth. Calicular margin adjacent to every CS1-3 produced into a short,
triangular apex, resulting in a moderately serrate calicular margin. Upper, outer edges of all septa light brown.
Septa hexamerally arranged in 4 complete cycles. Si extend up to 1.6 mm beyond calicular edge and reach
1/2 distance to columella, where each is bordered by a lamellar paliform lobe about 1.5 mm wide. Si are the only
independent septa. S2 as exsert as Si, about 4/5 width of an SI, bearing a palus of equal size, the P2 rising
slightly higher in the fossa and recessed slightly more from the columella than Pi. S3 as exsert as S1-2 but only
about 2/3 width of an S2. Each S3 bears a highly spinose palus (P3) 1.5- 1.7 mm in width, each pair of S3 within
a system fusing to its common P2 through several robust processes, the uppermost process at the level of
S2-P2 notch. P3 rise higher in fossa and are more recessed from the columella than are P2. S4 extend about 1.1 mm
beyond calicular edge and are about 2/3 width of an S3 in upper fossa. Deeper in the fossa, far below S3-P3 notch
and near columella, S4 are rudimentary, each pair of S4 joining its common S3 through 1-3 slender processes.
S4 do not bear paliform lobes. Fossa shallow to moderate in depth. Columella papillose, consisting of 15-20
fused granular elements, each about 0.25 mm in diameter.
Remarks. — The rudimentary nature of the S4 and the tenuous connection to their adjacent S3 distinguish this
species from other western Pacific Deltocyathus. D. philippinensis resembles D. eccentricus Cairns, 1979 (amphi-
Atlantic, 183-1000 m) in its S4 morphology, but differs in having only 48 septa (D. eccentricus often has pairs of
S5), an eroded central basal region, and ridged costae.

Type Locality. — Karubar stn 35: 5°46'45"S, 132°1 1T0"E (Banda Sea: Kai Islands), 156-305 m.
ETYMOLOGY. — The species name (Latin Stella, star) refers to the general shape of the corallum. It is treated
as a noun in apposition.
DESCRIPTION. — Corallum shaped as a shallow bowl, with a slightly convex base. Largest specimen examined
(Karubar stn 1) 12.3 mm in calicular diameter; holotype 10.6 mm in diameter and 3.9 mm in height. Centre of
base displays a flat to slightly concave attachment scar 1.3- 1.5 mm in diameter. Costae well defined and rounded,
separated by shallow, narrow intercostal striae. Costae covered with small, rounded granules. Most coralla
uniformly white, but several small fresh specimens from KARUBAR stn 18 are reddish-brown in colour.
Septa hexamerally arranged in 4 cycles, the 4th cycle complete at a GCD of about 6 mm; no specimens
examined have more than 48 septa. Si independent, extending about 0.5 mm beyond calicular edge, and reaching
about 1/2 distance to columella. Central most part of each Si bears a small Pi about 0.8 mm wide. S2 similar to
Si but slightly narrower, having pali (P2) that rise higher in the fossa and are more recessed from columella than
Pi. S3 highly exsert (1.5 mm beyond calicular edge) and quite thick (up to 0.45 mm), but only about 2/3 width ot
S2. P3 about 1.2 mm wide, bearing large, coarse granules up to 0.12 mm tall and fusing to their common P2 near
the columella. S4 about 0.75 mm exsert, each pair fusing to its common S3 in a short triangular lancet, producing
a highly serrate calicular margin. Inner edges of S4 fuse to adjacent P3 through 2 or 3 narrow processes below
S3-P3 notch. Inner edges of Si -3 slightly sinuous; edges of S4 dentate to laciniate. Fossa shallow. Columella
consists of 15-30 small (0.20 mm diameter) papillae, all fused at base level.

Remarks. — Deltocyathus Stella is distinctive in having quite exsert and thickened S3. The 12 S3 are not
spinose as in D. ornatus Gardiner, 1899 or lobate as in D. andamanicus , but simply prominent and thickened.
Another spinose Deltocyathus, D. heteroclitus Wells, 1984 (Pleistocene of Vanuatu), differs in having spinose
(not thickened) CS3, an irregular number of costal spines, and an incomplete 4th cycle.

TYPE Locality. — "Investigator" stn 236a: Andaman Sea, 315-555 m.
Description. — Corallum shaped as a shallow bowl, with a slightly convex base. Largest known specimen
(" Albatross " stn 5417) 21.1 mm in calicular diameter and 5.5 mm in height. Centre of base often bears a circular
scar 1.1 -1.5 mm in diameter, which is usually surrounded by a larger irregularly-shaped region up to 10 mm in
diameter characterised by reduced costal development, increased erosion, and often a lighter colouration. Costae
consist of thin, finely dentate ridges. Corallum usually uniformly light brown, exceptionally white or even light
yellow, the latter characteristic of specimens dead when collected.
Septa hexamerally arranged in 5 cycles, but the last never complete, most coralla having 4-16 pairs of S5,
which results in a total of 56-80 septa. Si extend about 1.8 mm beyond calicular edge and have slightly sinuous
inner edges, each Si internally bordered by a lamellar P| 1.7- 1.9 mm in width. Si, not being joined to any other
septa, are the only independent septa. S2 similar to Si but less wide, their P2 rising higher in the fossa and being
more recessed from the columella than Pi. S3 highly exsert, extending up to 3.8 mm beyond the calicular edge. In
large, well-preserved coralla, the lower outer edge of the S3 is hyperextended as a small (about 1 mm) lobe, this
lobe being compressed in the septal plane. Each S3 bordered by a large palus 1 .5-2.4 mm wide that rises higher in
the fossa and is more recessed from the columella than P2. Inner edges of P3 fused to their common P2. S4 small
and low, extending only about 1.5 mm beyond calicular edge, each pair fused to their common S3 to form
rectangular lancets, resulting in a highly serrate calicular margin. Inner edges of S4 fuse to their adjacent P3
through a series of 3-5 slender processes. In half-systems having pairs of S5, S5 are equivalent to previously
described S4, and S4 are same size as previously described S3. Upper, outer edges of CS1-3 entire, whereas those of
the S4-5 are laciniate. Fossa shallow; columella composed of 10-20 small (about 0.3 mm diameter) granular pillars
that are fused basally.
Remarks. — Although the holotype was not directly examined (deposited at the Indian Museum and not
available for loan), photographs of it were obtained and, along with ALCOCK's (1898) figure and description, the
holotype of 1 8 mm GCD and 62 septa appears consistent with the specimens identified above.
Distribution. — Philippines: Lubang Island; Sibuyan and Visayan Seas; Bohol Strait; Sulu Sea (Semirara
Islands); 187-333 m. Indonesia: Banda Sea (Kai Islands); Flores Sea (Selayar Island, Sulawesi); 340-385 m.

Type Locality. — "Siboga" stns 95 and 100: Sulu Archipelago, 450-522 m.
Diagnosis. — Corallum with a flat to slightly convex base and a small central basal scar; peripherally the
theca is thickened and abruptly upturned, resulting in a marked thecal edge. Largest known specimen (Karubar
stn 77) 21.8 mm in diameter. Costae low, wide rounded ridges covered with granules. Well-preserved specimens
show concentric bands of light brown pigmentation on the base and a light brown pigmentation on lower, outer
septal edges. Septa hexamerally arranged in 5 cycles, the 5th cycle complete (a total of 96 septa) at a GCD of
about 18 mm; however, pairs of S5 begin to appear in coralla as small as 4 mm GCD. In fact, S5 are usually more
visible in small, fiat-based coralla than in larger coralla where they are often rudimentary or even absent on the
peripheral, upturned calicular edge, even though their corresponding C5 are well developed. S1-4 extend equally
beyond calicular edge (1.4- 1.6 mm), the S5 being only 1/2 as exsert. Calicular margin serrate but not lanceted.
S 1-4 and Pi -4 arranged in typical deltocyathid fashion, but, as mentioned before, S5 rudimentary to absent,
especially near calicular edge of large coralla. S5 join their adjacent S4 very low in fossa near columella by a series
of 2-5 thin processes. Columella papillose.
Remarks. — Deltocyathus suluensis differs from D. magnificus Moseley, 1876, in having granular costae; a
central basal scar or eroded region; less exsert and less developed S5; and a smaller corallum. It differs Irom
D. rotulus (Alcock, 1898), another species with 5 cycles of septa, in having granular, convex (not serrate ridged)
costae; a serrate (not lanceted) calicular margin; smaller S5; and a papillose columella; and is usually lound in
shallower water (142-565 m vs 210-1986 m for D. rotulus).

Diagnosis. — Corallum discoidal, with a flat to slightly bowl-shaped base. Largest known specimen
("Albatross" stn 5582) 36 mm in calicular diameter. Centre of base always eroded and without costae; otherwise
Ci -5 thin, finely serrate ridges. Septa hexamerally arranged in 5 cycles (Si-2>S3>S4>S5), the 5th cycle complete at
a GCD of 30-32 mm. Each Si-2 and the adjacent pair S5 project as short rectangular lancets, producing a highly
serrate calicular margin. Pi -3 small, sometimes even absent (Fig. 16 b); however, P4 prominent (up to 4 mm
wide), forming a distinctive crown of 24 lobes. S5 rudimentary, each pair of S5 fused to their common S4 by
5-8 slender processes beginning near the S4-P4 notch and continuing to the columella. Fossa shallow, containing
a columella in the shape of a circular, undercut platform that supports numerous irregularly-shaped papillae.
Remarks. — This species is more fully described and illustrated by Cairns (1994). It is one of the few
species in the genus to attain 5 full cycles of septa and is unique in having such a well-developed P4 crown.

8 mm. Pairs of S5 join their common S4 by an elongate, porous lamella. All septa bear prominent pali or
paliform lobes, even S5 of larger coralla. Columella an elongate fusion of numerous papillae that rises as high as
the septa and thus there is no fossa.
REMARKS. — Deltocyathus magnificus, the largest species in the genus, is easily distinguished from
D. rotulus (Alcock, 1898) by its flat base, equally exsert septa, differently constructed columella, and smaller P4.

Type Locality. — "Challenger" stn 194: 4°34'S, 129°57'30"E (Banda Island, Banda Sea), 366 m (see
Cairns, 1995).
DIAGNOSIS. — Corallum elongate-conical, originally attached by a slender pedicel that is usually augmented by
a broad lateral thecal adhesion near the pedicel, which together form a broad, solid attachment. Largest known spec¬
imen (KARUBAR stn 71) 12.1 mm in calicular diameter and 16.0 mm in height, but most coralla are much smaller,
having a GCD of 6-8 mm. Theca coarsely granular and glisteny, the theca of well-preserved coralla commonly
pigmented a reddish-brown arranged in longitudinal stripes or circumferential bands. Some specimens, however,
have a smooth, usually longitudinally pigmented, theca. Theca quite thick, reinforced internally with deposits of
stereome; upper thecal edge forms a smooth circular rim about 0.4 mm around the upper, outer edges of the septa.
Septa hexamerally arranged in 4 cycles (S i>S2>S3>S4), the 4th cycle rarely complete, most coralla having 36-44
septa. Fossa deep. Columella consists of short, twisted lamellae swirled in the typical clockwise direction.
Remarks. — Conotrochus brunneus is similar to C. funicolumna (Alcok, 1902) but differs in having a
smaller corallum, less septa (usually 36-44 vs 48 for C. funicolumna ), a secondarily attached pedicel, a pigmented
corallum, and internal stereome. Also, in general, C. brunneus is found in deeper water than C. funicolumna.

TYPE Locality. — "Siboga" stns 159 and 259: (Kai Islands and Halmahera Sea), 411-487 m.
DESCRIPTION (emended). — Corallum conical to subcylindrical, having a circular calice up to 11 mm in
diameter and a corallum height up to 24 mm. Clusters of up to 30 coralla form pseudocolonies, each corallum
providing the substratum for the settlement of up to 6 additional coralla from its theca, resulting in a low, dense,
bushy agglomeration. The close proximity of multiple coralla often leads to fusion of their theca. Corallum
pedicel robust: PD:GCD up to 0.5. Theca covered with small, hollow granules and epithecal bands. Each corallum
internally reinforced with thick stereome. Base polycyclic. Transverse dissepiments sometimes present. Corallum
white. Theca extends up to 0.8 mm above upper, outer septal edges as a continuous rim, which is characteristic of
the genus.
Septa hexamerally arranged in 4 cycles, most coralla from Karubar stn 13 having 48 septa, although 36 septa
is also common in other specimens. Si 1.0- 1.2 mm exsert, having straight, vertical inner edges that border the
columella. S2 slightly less exsert and 3/4 to 4/5 width of an Si also having straight inner edges and occasionally
bordered by a narrow, lamellar to papillose paliform lobe. These P2 almost indistinguishable from columellar
elements and not always present. S3 slightly less exsert and 3/4 to 4/5 width of an S2, having slightly sinuous
inner edges, and sometimes bordered by a papillose or short lamellar paliform lobe, 2 of which sometimes unite
within a system forming a V-shaped structure before their common Si. In some coralla P3 are absent, rudimentary,
or irregular in development. S4 about 1/2 width of an S3 and have straight inner edges. Fossa of moderate depth,
containing a columella of granular papillae or short lamellae, but never swirled as in C. brunneus or
C. funicolumna.
Remarks. — ALCOCK (1902c: 13) stated that in this species "budding takes place near the calicular margin, is
fairly regular, and is a true gemmation." Based on re-examination of the syntypes and additional topotypic coralla,
it is clear that new corals occur over the entire theca in a very irregular manner (Fig. 16i) (not just the calicular
margin), and seem to prefer attachment to dead coralla or living corals not covered with an edge zone. This results
in corallum clusters of very irregular structure. Furthermore the bases of some coralla show a discrete margin at the
interface with the corallum on which it settled. Therefore, the clusters of coralla reported above are interpreted as
independent settlement of planulae, possibly clonemates, that form a pseudocolony much in ihe same way that
Desmophyllum dianthus (Esper, 1794), is known to form (CAIRNS, 1982).
ALCOCK (1902: 13) described L. oculeus as a colonial Conotrochus, very similar to C. hospes
(= C. brunneus). Even though L. oculeus is now interpreted as a solitary coral, it can be distinguished from
C. brunneus by having a tendency to form clusters or pseudocolonies, always having a white corallum, usually
having 48 septa, having a papillose columella (rarely sublamellar and never swirled), and often having either P2
and/or P3. This is believed to be the first report of this species and genus subsequent to their original descriptions.
Distribution. — Indonesia : Halmahera Sea; Banda Sea (Kai Islands); Bali Sea; 240-616 m. Elsewhere:
Malaysia (Celebes Sea off Sabah); South China Sea (southern Formosa Strait); 412-430 m.

Type Locality. — Off Cape Jaffa and Neptune Island, South Australia, 165-190 m.
DIAGNOSIS. — Corallum elongate-conical, straight, and usually budded from fragment of the parent corallum.
The only well-preserved Celebes Sea specimen ("Albatross" stn 5585) is 9.5 mm in calicular diameter, 5.0 mm in
basal diameter, and 12.4 mm in height. Calicular margin circular and evenly serrate. Theca thin, with hollow,
conical spines. Corallum white. Septa hexamerally arranged in 4 to 5 cycles (S i>S2>S3>S4>Ss); however,
development of Sa and S5 quite irregular. Specimen from "Albatross" stn 5585 has 44 septa and includes systems
with 1 pair of S4, 2 pairs of S4, and even 1 system with 2 pairs of S4 and 1 pair of S5. Slender paliform lobes (P3)

Type Locality. — Senegal, 97-85 m.
DESCRIPTION. — Corallum ceratoid, usually curved about 45°. Approximately half of the coralla examined
originated by extratentacular budding from the edge zone of a parent corallum, their pedicels narrowing to a slender,
open base only 0.6-0.7 mm in diameter. Other coralla firmly attached to a substratum through a robust pedicel up
to 4.5 mm in diameter (PD:GCD = 0.18-0.30), these coralla assumed to have originated from planular settlement.
Largest known specimen (MUSORSTOM 3 stn 140) 14.9 x 18.0 mm in calicular diameter, 15.8 mm in height, and
4.5 mm in pedicel diameter; however, most coralla are less than 13 mm in GCD. All costae (Cm) consist of low,
rounded ridges, separated by equally wide, shallow furrows. Costae covered with tiny granules, 4 or 5 occurring
across the width of a costa. Theca quite thin. Many coralla display small scars of bud detachment on their theca,
some bearing as many as 25 shallow, circular (0.6-0. 7 mm in diameter) concavities. Although some coralla are
completely white, most coralla are reddish-brown, especially intense near calicular edge and fading to white at base.
Septa hexamerally arranged in 4 cycles, only larger coralla having pairs of S5, up to 66 septa. Si highly exsert
(about 2.9 mm), having straight, vertical inner edges that attain the columella. S2 slightly less exsert (about
2.5 mm), about 4/5 width of an Si. Both Si and S2 occasionally bear an irregularly-shaped paliform lobe that
mingles with the columella. S3 about 1.2 mm exsert and only 1/2 width of an S2- Each S3 bears a lamellar
paliform lobe about 1.2 mm wide, together forming a palar crown. S4 as exsert as S3 but only about 2/3
the width, with finely dentate inner edges, and attenuating in size low in fossa. If a pair of S5 flanks an S4, that
S4 also bears a paliform lobe, the P4 being larger than the P3 and occurring higher in the fossa and more
peripherally. Pairs of S4 flanking Si and S2 form low calicular lancets resulting in a serrate calicular margin.
Fossa of moderate depth, containing a crispate, twisted columella. Endothecal dissepiments often present.
Remarks. — Previous records of A. marchadi from the Atlantic and southwest Indian Ocean have been of
unattached specimens, presumably resulting from asexual budding. However, among the 28 lots reported above,
11 lots (mainly from MUSORSTOM 1-3 and Corindon 2) contained exclusively attached specimens; 11 lots
(mostly "Albatross" and ZMUC specimens) contained only free forms; and 6 lots (from all sources) contained
a mixture of both forms. Buds detach at a very early stage, probably because their attachment to the parent is so
small and tenuous. Examples of buds still attached to the parent corallum are uncommon, rarely exceeding 2 mm
in length; likewise, many already detached buds as small as 4 mm length were found in the study material.
We therefore conclude that the buds probably detach at a corallum length of 2-4 mm.

Type Locality. — Sandal Bay, Lifu, Loyalty Islands, 73 m.
DIAGNOSIS. — Corallum composed of a cluster of elongate-conical corallites, each originating from a common
basal coenosteum or the lower pedicel of a larger corallite. Largest known corallite (CORINDON 2 stn 248)
14.9 mm in GCD and 28.7 mm in height, but calices of most other corallites examined less than 5 mm in
diameter. Ci and often C2 highly ridged, producing a calice hexagonal in outline. Corallum white. Septa of most
corallites hexamerally arranged in 3 cycles (Si>S2»S3), only the larger corallites having a 4th cycle (48 septa).
Highest cycle septa (S3 or S4, depending on size) rudimentary, often absent from upper corallum. Fossa quite deep;
no columella.
REMARKS. — Previously reported specimens of T. tenuescens were small (GCD < 4.5 mm) and thus had only
3 cycles of septa. A colony from Corindon 2 stn 248, having a much larger calice (/.«., 14.9 mm GCD) and
4 cycles of septa, is included without hesitation because from its base bud two smaller corallites (GCD = 4.1 and
4.9 mm), each having only 24 septa and being similar to previously known specimens.
The colony from KARUBAR stn 22 has the C1-2 on the lower pedicel prominently ridged and extending outward
onto the common coenosteum. Exothecal dissepiments bridge adjacent Ci-2, forming chambers of tissue radiating
outward from the base of each corallite, each a potential bud.
This species is more fully described and illustrated by CAIRNS (1995).

Diagnosis — Phaceloid colonies composed of a few robust, trochoid corallites, the largest known corallite
29 8 x 36 7 mm in calicular diameter, 41.6 mm in height, and 18.1 mm in pedicel diameter. Base and lower
pedicel thickened with concentric rings of hollow chambers formed by layers of exothecal dissepiments that bridge
raised costae. Corallum white. Septa hexamerally arranged in 5 cycles (Si>S2>S3>S4>Ss), the largest corallite
also having 8 pairs of S& and even 1 pair of S7 in its end systems (/.<?., 1 16 septa). Small, lamellar paliform lobes
occur before S4, seemingly paired within each half system. Fossa deep; columella composed of granular rods that
are strongly fused into a massive structure.

DIAGNOSIS. — Corallum composed of a relatively small phaceloid clump of elongate-conical corallites, the
largest Philippine corallites (MUSORSTOM 3 stn 131) 8.8 x 10.1 mm in calicular diameter, 13.5 mm in height, and
4.5 mm in pedicel diameter. Corallite bases reinforced with concentric rings of hollow chambers (best seen in a
cross section of the pedicel), which is characteristic of the genus. Corallum primarily white; however, faces
of S1-2 usually bear reddish-brown crescent-shaped bands that parallel the curved septal edge. Septa hexamerally
arranged in 4 cycles (Si>S2>S3>S4), the Si being highly exsert. A crown of 12 P3 encircles the trabecular
columella.

7.6 mm in distal calicular diameter. Main corallite of holotype colony 8.3 cm long and 11.8 mm in calicular
diameter, bearing 14 smaller corallites, most of which are assumed to be the result of independent settlement of
planulae. Corallites budded from edge zone of parent corallite as well as from common basal coenosteum. On
elongate corallites the edge zone covers only a small distal region of the corallum, whereas the remaining theca is
often encrusted with epifauna (serpulids, bivalves, etc.), including juvenile corallites of R. data. Thus, an elongate
corallite may bear numerous, irregularly spaced smaller corallites, the secondary corallites resulting either from true
budding or larval settlement. Well-preserved pedicels of this species indicate that the Ci-2 form prominent ridges
that radiate from the corallite base onto the adjacent coenosteum where exothecal dissepiments form over these
raised costae, characteristic of the genus Rhizosmilia. In the more distal parts, costae (Cm) are broad and convex,
covered with very fine granules, and separated from one another by narrow intercostal striae. Ci-2 usually slightly
more prominent than C3-4 and frequently pigmented a light reddish-brown, the remainder of the corallum being
white.
Septa hexamerally arranged in 4 complete cycles: Si>S2>S3>S4- Si highly exsert (up to 3.5 mm), having
straight, vertical inner edges that reach the columella. S2 slightly less exsert (up to 3.0 mm), about 2/3 width of
an Si. S3 about 1/2 width of an S2, and only about 2.3 mm exsert. Each S3 bordered by a thin lamellar paliform
lobe 1.3- 1.5 mm in width, the 12 P3 forming a distinct palar crown. S4 only about 1.8 mm exsert, about 1/2
width of an S3. Fossa of moderate depth, containing a crispate columella. Endothecal dissepiments common in
elongate coralla, usually visible only in longitudinal section.
REMARKS. — Five other species are known in Rhizosmilia: R. maculata (Pourtales, 1874); R. gigas (van der
Horst, 1931); R. sagamiensis (Eguchi, 1968); R. gerdae Cairns, 1978; and R. robusta Cairns, 1993. R. data is
distinguished in having elongate, subcylindrical corallites and pigmented Ci-2-
Rhizosmilia elata is similar to Anomocora in having elongate coralla with endothecal dissepiments and
irregular budding, but can be distinguished by its well-developed P3, the fact that its buds do not detach, and by
its characteristic basal structure of raised costae overlain with exothecal dissepiments.

point outward in all directions from the axis. Colony from Madagascar 17 cm long and 15 mm in diameter
(including the gorgonian axis), consisting of approximately 200 corallites. Philippine colony originally of similar

size but encrusting a thinner antipatharian axis. Corallites elongate-conical to cylindrical and up to 7.9 mm in
diameter, although most are less than 5 mm in GCD. Corallites rise up to 7 mm above coenosteum, but most are
considerably lower. Coenosteum between corallites striate and white. Costae low and convex, bearing 3 or 4 small
rounded granules across the width of each costa. Upper theca and outer septal elements light reddish brown.
Septa hexamerally arranged in 3 to 4 cycles, a corallite less than 5 mm GCD usually having only 3 cycles
(Si»S2>S3), and larger corallites of 6.5 mm GCD having up to 44 septa (Si-2>S3>S4), but none having a full
4th cycle of 48 septa. Si highly exsert (up to 1.1 mm) and thick (0.2 mm), but not very wide, their inner edges
extending only about 1/2 distance to centre of calice. Lower, inner edges of Si sometimes bear a small (0.25 mm
wide), irregularly shaped paliform lobe. S2 much less exsert (0.6-0.7 mm) and only about 1/2 width of an Si:
S2 may also bear a larger paliform lobe up to 0.33 mm in width. S3 rudimentary, having laciniate inner edges. In
septal systems of corallites bearing pairs of S4, the S2 are accelerated to the same size of an Si, the S3 takes the
size of a normal S2 and has a paliform lobe, and the S4 are rudimentary, as previously described for the
unaccelerated S3. Fossa of moderate depth, containing a papillose columella, the rods often fused into a solid,
central structure.
REMARKS. — The 2 colonies from the Philippines and northwest Madagascar were the host to the same species
of hapalocarcinid crab (see K.ROPP & MANNING, 1995).

Genus SYMPODANGIA nov.
Type SPECIES. — Sympodangia albatrossi, here designated.
ETYMOLOGY. — The genus name Sympodangia (Latin sympodium, structure resulting from alternate
branching + angia , a common coral generic suffix) refers to the growth mode of this coral. Gender: feminine.
DIAGNOSIS. — Colonial, small corallites closely packed in short sympodial branches. No individualized
columella; no endotheca. Axial edge of septa dentate.
REMARKS. — This genus is of uncertain affinities. The dentate septal edge is unlike typical rhizangiids.
Sympodial growth suggests affinities with Madrepora, but branches are stouter and less zigzag-shaped. Also, there
are more septa than in a Madrepora. Individual calices resemble those of Hoplangia, a monospecific genus, but
which has stronger Si.

137
DESCRIPTION. — Small (rarely more than 4 cm in diameter), bushy colonies formed by closely spaced
sympodial budding, such that corallites from adjacent branches often fuse to one another. Adjacent corallites may
also be linked by slender (1 mm diameter), solid, coenosteal bridges, although this is far less common. Holotype a
branch fragment 35 mm long consisting of 20 corallites. Calices circular to slightly elliptical, ranging from 2.5 to
4.2 mm in diameter. No marked costae, the theca homogeneously covered with low, closely spaced, rounded
granules 90-120 pm in diameter, the larger-sized granules occurring only on coenosteum that encrusts a barnacle
valve substratum. Corallum light yellow-brown in colour.
Septa hexamerally arranged in 4 cycles, the 4th never complete. A full 3rd cycle of septa (a total of 24 septa)
present in calices of 2.4 mm GCD, and a maximum number of 36 septa (a pair of S4 in each system) is achieved
at GCD of about 3.4 mm. Si exsert (0.3-0.6 mm), having straight, vertical inner edges that bear 3-5 small
(85-100 pm diameter), cylindrical papillae on their lowermost edges adjacent to the columella. Accelerated S2
(those in systems having a pair of S4) about 0.2 mm exsert and 3/4 width of an Sr, lower, inner edges of S2
coarsely dentate, the teeth about 0.2 mm in width, beginning slightly higher in fossa than Si papillae. S3 slightly
less exsert than S3 but about equal in width, their inner edges bearing even larger teeth (up to 0.3 mm width) that
extend slightly higher in fossa than those of the S2. S4 less exsert and about 3/4 width of an S3, their inner edges
finely dentate for most of their length. Septal faces covered with tall (up to 90 pm), blunt granules. Fossa deep and
narrow. Columella papillose, but quite small, composed of 1-4 papillae of equal size to those on the lower edges
of the S 1 .

2 syntypes of Cladocora moseleyi: 30 fathoms (= 55 m), 1 colony, larger syntype (= lectotype) (BMNH, no register
number); 10 fathoms (=18 m), single corallite, smaller syntype (paralectotype), ? Polycyathus (BMNH no register
number).
Type Locality. — Zamboanga, Mindanao, Philippines, 55 m.
DESCRIPTION. — Lectotype collected alive, a compact colony of ca. 27 clustered corallites of various sizes,
some incomplete (damaged). Colony comprises some elongate parallel incomplete corallites, 10-20 mm high,
lower end broken. Endotheca can be seen inside the fractured corallites (parasmiliid character). In upper part colony
spreads laterally and short corallites overgrow the elongate ones, budding from a basal sheet as in Phyllangia.
Larger corallites up to 5 x 6 mm in calicular diameter. Septa little exsert (Si most exsert of all). Outer surface
quite smooth, locally with very attenuate costae covered by fine granules. Smaller calices with only 3 cycles ol
septa; larger calices with incomplete 4th cycle (for example 14 S4). Septa decreasing in width from Si to S4. Large
Si with straight vertical axial edge. One distinct large paliform lobe, with vertical axial edge, separated by notch
from corresponding septum, associated with S2 in smaller calices, or with S3 in larger calices (when S4 present in
same half system). Narrower septa of subsequent cycles with more sloping (less vertical) axial edge lrequently
bearing 2 or 3 narrow lobes, subhorizontally or obliquely upward directed. These narrow lobes very different trom
the main paliform lobes (but unlike septal dentation as in true Astrangia). Central area of fossa (up to ca. 1/3
calice diameter) occupied by columella composed of lobes similar to paliform lobes, but smaller.

S. D. CAIRNS & H. ZIBROWIUS
Remarks. — Moseley (1881) described material said to originate from 2 unnumbered shallow stations
(10 and 30 fathoms) off Zamboanga (Philippines), as a new species, Cladocora conferta. Cladocora moseleyi was
introduced by FAUSTINO (1927), who reproduced Moseley's description and illustration but with no new data as a
nomen novum in replacement for Moseley's Cladocora conferta, the latter then considered as a junior homonym
of Cladocora conferta (Dana, 1846). In fact, Dana’s (1846: 380-381, pi. 27, fig. 6) poorly described and illustrated
Caryophyllia conferta, of uncertain origin (possibly the West Indies), had been placed by later authors (starting
with H. Milne Edwards & Haime, 1849: 308) in the genus Cladocora, or even been assimilated (Vaughan,
1901: 298) as the West Indian Cladocora arbuscula (Lesueur, 1821), apparently without reexamining Dana's type.
Remaining of doubtful generic attribution, Dana's species may not be congeneric with Moseley's species.
Moseley's (1881) description of Cladocora conferta from the 30 fathoms station is based on a colony with many
clustered corallites (poorly illustrated). This syntype is here selected as the lectotype (BMNH, no register number).
It is not a Cladocora, but a Colangia, and closely resembles the West Indian Colangia immersa Pourtales, 1871,
type species of the genus. Colangia immersa should be restudied in detail. First described from Florida on the basis
of dead material from deep water, it more likely is a species of shelf depths. Moseley's second Philippine syntype
of Cladocora conferta, from the 10 fathoms station, (BMNH, no register number), is a different species, not a
Colangia: the elongate narrow corallite with only 3 cycles of septa and a lateral bud may be a Polycyathus. No
other specimen of Colangia has yet been recognized in the western Pacific. Elsewhere, the genus is known only
from the West Indies. This and the resemblance of Moseley's lectotype with the West Indian species is troubling.
Perhaps the origin is confused, the material not being from the Philippines. Confused origins of "Challenger"
material have been pointed out elsewhere.
DISTRIBUTION. — If indicated origin authentic (see Remarks), Colangia moseleyi is known only from
Mindanao (Philippines), 55 m (type locality).

DESCRIPTION (Specimen from "Albatross" stn 5543). — Corallum a bushy, irregularly branched colony of
about 30 corallites showing 5 generations of budding. Colony 9 cm in width, composed of elongate-conical
corallites, the largest measuring 12.1 x 12.5 mm in calicular diameter and 37 mm in length. Each corallite bears
up to 7 buds that originate from the edge zone just below calicular edge. C1-3 usually slightly ridged near calicular
edge, flat and granular, like the C4, on lower 2/3 of corallum. Corallum uniformly white.
Septa hexamerally arranged in 3 cycles (Si>S2>S3), S4 represented only as small exsert costosepta at calicular
margin. Si about 1.8 mm exsert, quite narrow (only about 2/5 calicular radius in upper corallite), having straight,
entire inner edges that thicken deep in fossa near columella. S2 about 1.1 mm exsert, 2/3 width of an Si, having
coarsely dentate inner edges near columella. S3 about 0.9 mm exsert, 2/3 width of an S2, having highly laciniate
inner edges. S4 about 0.4 mm exsert, occurring only at calicular edge. Fossa very deep and wide. Columella
variable, but most often composed of crispate lamellae that are attached to lower, inner edges of Si -2. Endothecal
dissepiments present.

REMARKS. — The Philippine specimen differs from most Atlantic specimens in having larger corallites,
a more robust colony, and a much deeper fossa. But, C. arbuscula is a variable species, and Atlantic specimens are
known to have even larger corallites, colonies of 4 corallite generations, and equally deep fossae. Since all other
characters are remarkably similar, this specimen, as well as one reported from Japan (Cairns, 1994), are identified
as C. arbuscula. The second author is dubious about the identification of the Philippine specimens with a species
known from the Atlantic, believing that there are probably some characters as yet not fully understood that
differentiate the two taxa.

Genus CONFLUPHYLLIA nov.
Type Species. — Confluphyllia juncta, here designated.
DIAGNOSIS. — Colonial, extratentacular budding forming bushy colonies. Branch anastomosis common,
adjacent corallites also united by solid, cylindrical to sheet-like coenosteal bridges. No pali. Columella fascicular.
Tabular endothecal dissepiments present.
Remarks. — Confluphyllia is similar to Goniocorella , both genera having the same type of colony formation
as well as solid coenosteal bridges, but differs in having a robust, fascicular columella, Goniocorella having none.
Confluphyllia is further differentiated from Goniocorella by having more septa (up to 42 vs 24), which are more
exsert and wider; ridged C1-2; and larger-diameter corallites. Confluphyllia differs from Coenosmilia in having a
more robust colony that is reinforced with coenosteal bridges, and a fascicular columella ( Coenosmilia has a
crispate columella).

Description. — Corallum bushy, produced by closely-spaced extratentacular budding from the edge zone of
parent corallites, resulting in frequent branch anastomosis. Colonial structure reinforced by solid coenosteal bridges
that link adjacent corallites, as in Goniocorella. Coenosteal bridges circular in cross section (about 1 mm in
diameter), elliptical in cross section, or lamellar, the latter shape joining two adjacent corallites by a thin
coenosteal sheet several mm long. Holotype colony 7 cm wide, consisting of about 85 corallites, one (perhaps the
founder corallite) 6.5 cm in length. Ci slightly ridged, especially near calice, and usually white. C2 may also be
ridged, but only near calice. Otherwise, theca covered with low, rounded (0.2 mm diameter) granules and light
yellow-brown in colour. Edge zone on corallites extends about 7 mm from calice.
Septa hexamerally arranged in 4 cycles, the last cycle not complete. Corallites less than 4 mm in GCD have 24
or less septa, but larger corallites (up to 7.2 mm in GCD) have several pairs of S4, the most common
complements being 36 or 38 septa, although some corallites have as many as 42 septa. Si exsert (1.3- 1.5 mm),
having straight, vertical inner edges that extend to the columella. S2 less exsert (about 0.8 mm) and only 0.8 width
of an Si, also having straight inner edges that fuse with the columella deep in fossa. S3 about 3/4 exsertness and
width of an S3. S4 2/3 width of an S3. Fossa deep, containing a narrow fascicular columella consisting
of 1-5 thick, granular elements.

Diagnosis. — Corallum a narrow, regular cone with a blunt rounded base. Largest known specimen (Deki,
Ambon) 4.0 mm in calicular diameter and 8.6 mm in height. Costae broad and flat, covered with small (about
20 ^tm in diameter) granules arranged 5 or 6 across width of each costa. Intercostal furrows deep and narrow but
wider towards theca, undercutting adjacent costae. Inside corallum, aligned with each intercostal region, is a row of
small (110-120 |am) shallow depressions, which, by erosion following the death of the coral tend to become pores.
Corallum white. Septa hexamerally arranged in 3 complete cycles: S i>S2-3- Six P2 form a palar crown that

Type Locality. — "Challenger" stn 192: 5°49'15"S, 132°14'15"E (Kai Islands, Banda Sea), 136 m.
Diagnosis. — Corallum compressed, the calice elliptical (GCD:LCD = 1.15-1.25) and the thecal faces
meeting in sharp edges that, on the lower corallum, project as much as 4 mm as thick, solid edge crests. Largest
Philippine specimen (MUSORSTOM 3 stn 88) 1 1.8 x 18.3 mm in calicular diameter, which is close to the largest
recorded size. Four cycles of ridged costae (Cm) corresponding to Si -4, but C5 not corresponding to a septal cycle
(no S5). Edge crests also ridged, as though by costae, but these ridges oriented perpendicularly to thecal costae.
Septa hexamerally arranged in 4 complete cycles: Si>S2>S3»S4, the S1-2 being highly exsert and extending to
the columella. Columella papillose, consisting of 5-12 robust pillars; depending on the individual the columellar
pillars may be circular or lamellar in cross section.
Remarks. — Three relatively large specimens (MUSORSTOM 3 stns 88, 91, 102) differ in having their
4 lateral Ci swollen and protuberant in the upper 8-10 mm of the theca (Fig. 18h). This variation was previously
reported for a Japanese Pleistocene specimen (CAIRNS, 1994). Alatotrochus rubescens is more fully described and
illustrated by Cairns (1994).

Type Locality. — "Siboga" stn 256: 5°26.6'S, 132°32.5'E (Kai Islands, Banda Sea), 397 m.
DIAGNOSIS. — Corallum conical but slightly compressed, resulting in an elliptical calice with a GCD:LCD of
1.1 -1.2. Largest Indonesian specimen (Karubar stn 7) 10.1 x 11.2 mm in calicular diameter and 10.4 mm in
height. Costae ridged, often discontinuous, and separated by broad intercostal furrows. Five cycles of costae usually
present on coralla having only 4 cycles of septa, the C5 terminating at the calicular margin as exsert spurs without
septal continuation within calice. Thecal edges rounded in upper corallum but on lower corallum faces meet in an
acute, non-carinate, angle. Corallum white. Septa hexamerally arranged in 4 cycles (44-48 septa): Si>S2>S3>S4,
the Si being highly exsert. Six thin lamellar P2 encircle a papillose columella.
Remarks. — "Cryptotrochus" venustus differs from the type-species C. javanus Cairns, 1988, in having one
more cycle of costae; much wider and shallower intercostal regions; costae of independent origin; and a slightly
compressed corallum (that of C. javanus is conical). Because of these significant differences, C. venustus is not
confidently assigned to Cryptotrochus ; its systematic position is elaborated on in greater detail by Cairns (in
press).

Type Locality. — "Siboga" stn 59: 10°22.7'S, 123°16.5'E (Savu Sea), 390 m.
DIAGNOSIS. — Corallum conical, the largest Indonesian specimen (a syntype) 6.5 x 6.7 mm in calicular
diameter and 9.2 mm in height. Calice almost perfectly circular: GCD:LCD = 1.02-1.05. All costae bear a row of
outward projecting granules, as well as 2 rows of laterally oriented granules that project across the deep intercostal
furrow. Corallum white. Septa hexamerally arranged in 4 complete cycles: Si>S2>S3»S4- Si highly exsert, their
upper edges being coarsely dentate and inclined inward toward fossa. S4 considerably less exsert and less wide, but
as thick as an S3, their septal faces often lacking granules. Within each septal system a pair of lamellar P3 fuse in
V-shaped structures before their common P2. Fossa shallow if any; columella papillose.
Remarks. — As previously discussed (Cairns, 1989a, 1994), Notocyathus venustus is very similar to
N. conicus (Alcock, 1902), the coralla of small specimens being difficult or impossible to distinguish. To
reiterate, N. venustus differs in having a nearly circular calice and thus a lower GCD:LCD (1.02-1.05 vs 1 .01-1.22
for N. conicus), and more exsert S 1-2 and proportionally less exsert S4. In large specimens of N. venustus, S3
become almost as wide and exsert as the S2, but the S4 remain quite small and thin. In large specimens of
N. conicus, the S4 are only slightly less exsert and less wide than the S3. This species is more fully described and
illustrated by Cairns (1989a, 1994).

DIAGNOSIS. — Corallum bowl-shaped, with a gently rounded base. Asexual reproduction through transverse
division not observed in this species. Coralla usually less than 7.5 mm in calicular diameter. Costae equal in
width, separated by deep intercostal furrows of about the same width. Each costa bears a row of outward-projecting,
blunt spines as well as smaller spines that project into intercostal furrows. Corallum white. Septa hexamerally
arranged in 4 complete cycles above a GCD of about 3.5 mm; 24 septa are present in smaller specimens, rarely
with any intermediate number. Septal formula: Si>S2>S4>S3, all septa being equally exsert. Si independent; pairs
of S3 join S2 and pairs of S4 to S3 within each septal system. P2-3, and occasionally Pi, present. Columella
papillose.
Remarks. — As implied by Cairns (1995), the genus Deltocyathoides should be employed for those
"peponocyathid" species that do not reproduce by transverse division, and the name Peponocyathus for those

Type Locality. — Neogene of Taiwan, Kyushu, and Honshu, and Recent of Toyama Bay, Japan.
DIAGNOSIS. — Anthocaulus not yet known for this species. Anthocyathus cylindrical (usually wider than
high), often with a flat base, the result of asexual transverse division. Anthocyathi in process of division rare (but
see Fig. 18i), the corallum base appearing "unfinished" or open (thickened closing deposit not yet developed),
characteristic of a recent fission from a parent corallum. Corallum rarely over 4.0 mm in calicular diameter. Costae
equal in width and covered with fine granules; costae separated by relatively wide intercostal furrows, often as wide
as the costae. If C4 are present, they originate on the horizontal flat base, not the vertical thecal walls. Corallum
white. Septa hexamerally arranged in 3 to 4 cycles, the 4th cycle never complete, most coralla having 24 or
36 septa: Si>S2-3. Small pali present before all but last septal cycle.
Remarks. — Peponocyathus minimus is similar to P. folliculus, both species being known from the
Philippine region. CAIRNS (1989a) mistakenly included 3 lots of P. minimus in a previous account of
P. folliculus (see synonymy). P. minimus differs in having a short, squat corallum (that of P. folliculus is
usually higher than wide); a flat base, not rounded; and intercostal furrows almost as wide as the costae (those ot
P. folliculus being very narrow and the costae quite wide). Furthermore, in P. minimus pairs of C4 originate on
the anthocyathus base, in P. folliculus on the thecal edges.
Peponocyathus minimus is described in greater detail by MORI & MlNOURA (1983) as Cylindrophyllia
orientalis.

Type Locality. — "Siboga" stn 95: 5°43'N, 119°40'E (Sulu Archipelago, Philippines), 522 m.
Diagnosis. — Corallum variable in shape: viewed from the side, most coralla are trapezoidal, the basal
(shortest) edge often being straight or slightly curved. Other coralla triangular in profile or bowl-shaped. All coralla
laterally compressed, resulting in an elliptical calice with a GCD:LCD = 1.50-1.65. Largest specimen (Karubar
stn 2) 17.9 x 24.8 mm in calicular diameter and 20.8 mm in height. Thecal edges rounded and occasionally
slightly protuberant near corallum base. Highly ridged, vertically oriented costae continuous from calice to base,
extending onto edge protuberances. Costae bear 1 apical row of coarse teeth and smaller, laterally oriented granules.
Intercostal furrows deep. Corallum white. Septa hexamerally arranged in 4 to 5 cycles (see Remarks):
S|>S2>S4>S3 or Si>S2>S3>S5>S4- Lamellar pali occur before all but last septal cycle (P1-3 or P1-4), the P2 and
2 P3 within each system in a chevron-shaped arrangement. Columella linear-papillose.
Remarks. — Although "T." pileus is similar to the type species T. lessonii (Michelin, 1842) in palar
configuration, it differs in costal origin and ornamentation; depth of intercostal regions; columellar structure; and
in lacking thecal edge crests. Discussed in greater detail by Cairns (in press), it is doubtful that T. pileus should
remain in the genus Tropidocyathus.
All specimens obtained from the Indonesian region differ from typical "T. "pileus in having more than 4 cycles
of septa, often a full 5th cycle (96 septa) or pairs of S5 in the 4 systems adjacent to the principal septa, resulting
in 80 septa, some coralla even having a few pairs of S6- This higher number of septa does not seem to be related
to a larger corallum size, since specimens as small as 9.8 mm in GCD (e.g., Karubar stns 3, 7) have a lull
5th cycle. Coralla having 5 cycles of septa are often triangular (not trapezoidal) in profile and have finer (thinner)
costae, their C5 originating on the thecal faces 2-7 mm above the base.
This common Indo-West Pacific species is more fully described and illustrated by Cairns (1989a, 1994).

Type Locality. — Karubar stn 2: 5°47'00"S, 132°1 1'35"E (Kai Islands, Banda Sea), 209-240 m.
Etymology. — The species name (Latin labidus , slippery) is an allusion to the smooth thecal surface.
Description. — Corallum compressed-conical, resulting in a GCD:LCD of 1.06-1.23. Holotype 6.4 x
7.9 mm in calicular diameter and 10.5 mm in height; largest specimen (DEKI stn 52) 9.8 x 11.4 mm in calicular
diameter and 13.2 mm in height. Tip of base pointed, covered by the slender lower distal edges of the 12 C3; C1-2
originate about 0.5 mm above basal tip; C4 originate 1. 5-3.0 mm above tip. C4 on centre of thecal faces originate
highest on face, whereas C4 near thecal edges originate lowest, such that the points of origin of the 6 pairs of C4
on either thecal face form a crescent (Fig. 20d), the arc of which encircles the basal tip. Each costa bears a row of
low, large (200-250 pm in diameter), smooth, rounded granules, producing a slippery texture. Intercostal furrows
deep and narrow (50 pm). Corallum theca pale orange, as in T. lessonii , but basal tip and all calicular elements
white. Dead specimens also uniformly white.
Septa hexamerally arranged in 4 complete cycles: Si>S2>S4>S3 (48 septa). Si highly exsert (up to 1.6 mm),
having highly sinuous inner edges. S2 slightly less exsert, about 4/5 width of an Si, also having sinuous inner
edges. S3 much less exsert (about 0.8 mm), about 2/3 width of an S2, having sinuous inner edges. S4 as exsert as
S3, but wider than the S3 (almost as wide as the S2), having straight, thin inner edges. A crown of 12 sinuous-
lamellar P 1 -2 encircles the columella, the Pi about 0.5 mm in width, the P2 about twice that width. A 2nd crown
of 12 P3, each P3 about the same width of a P2, stands higher in the fossa. Inner edges of P3 slightly recessed from
columella, each pair of P3 within a system forming a chevron arrangement with its common P2. All septa and
pali bear tall (up to 0.1 1 mm), slender, pointed spines. Fossa shallow. Columella consists of a line of 3-6 robust
papillae, fused at their bases to inner edges of Pi -2.
Remarks. — "Tropidocyathus" labidus differs from the other two Recent species of Tropidocyathus by having
a smaller adult corallum; a corallum that is only slightly compressed and bears no edge crests or protuberances;
a distinctive costal insertion pattern; and a smooth, coarse costal granulation, quite unlike that of the other
species. Like "T. " pileus, it probably should form the basis of a separate genus.
Distribution. — Indonesia: Banda Sea (Kai Islands); Arafura Sea (southeast of Tanimbar Islands); 206-
390 m. Elsewhere : Amami 0 Shima, Ryukyu Islands; 422-425 m.

Diagnosis. — Corallum small and conical, rarely exceeding 4 mm in calicular diameter or 7 mm in height.
Base of corallum irregularly shaped as the result of regeneration from a parent fragment. Costae broad and serrate,
separated by thin, deep intercostal furrows. Corallum white. Septa hexamerally arranged in 4 cycles:
Si>S2>S3»S4. Inner edges of each Si-3 bear 1-3 narrow paliform lobes, the lowermost merging with
the papillose columella.
Remarks. — Since its original description, which was based on material from the Philippines, this species
has been reported from the southwestern Indian Ocean and north of New Zealand, and is probably widespread
throughout the Indo-West Pacific. It is more fully described by Cairns (1989a).

TYPE Locality. — Adventure Bank, Mediterranean, 168 m.
DIAGNOSIS. — Corallum cylindrical and quite small, rarely over 7 mm in length and 1.0- 1.3 mm in diameter,
straight to serpentine. Some coralla firmly attached along one side of the corallum, others attached at random
points of their theca to sand grains, pebbles, or foraminifera. One specimen (MUSORSTOM 3 stn 140) was laterally
attached to a dead specimen of Heteropsammia. Epitheca bears 2 sets of ridges: transverse, circumferential ridges,
and 16, 18, or 20 longitudinal costal ridges, which form a grid-like pattern of rectangles. Within each rectangle is a
chalky white thecal spot. Septa usually octamerally arranged in 2 cycles, the Si much thicker than the S2; among
the Karubar specimens there was an almost equal division between the typical octameral form (having 16 septa)
and decameral specimens (having 20 septa), and one specimen having 18 septa. These septal symmetries are
indicated in the Material Examined section. Furthermore, some small specimens have a hexameral symmetry. All
septa have highly sinuous inner edges. Columella a single twisted or trefoil ribbon.
Remarks. — This minute, cryptic species has one of the smallest calicular diameters of all scleractinian
corals. It is more fully described and illustrated by Zibrowius (1980), Cairns (1989a), and Cairns & Parker
(1992).
Distribution. — Philippines : Verde Island Passage; Sulu Sea (Mindoro and Panay); Sibuyan Sea; 97-194 m.
Indonesia: Halmahera Sea; Banda Sea (Kai Islands); 141-282 m. Elsewhere: nearly cosmopolitan in tropical and

Type Locality. — Hawaiian Islands (depth not given).
DIAGNOSIS. — The specimens reported herein are all relatively small coralla of the coalitum form, the largest
(CORINDON 2 stn 216) only 16.4 x 29.9 mm in calicular diameter and 29.2 mm in height. Angle of thecal edges
ranges from 7 1 °- 1 1 3°; angle of thecal faces, 33°-43°. Thecal faces slightly convex and coarse in texture, meeting in
acute thecal edges that often bear low, discontinuous crests. Calicular edge smooth. Theca of well-preserved
specimens reddish-brown, often more intensely striped along the Ci-3, as in F. politum Cairns, 1989.
Pedicel elongate and slender (1.1-1. 5 mm in diameter), having 6 protosepta in the basal disc. Septa
hexamerally arranged in 6 cycles: Si-3>S4>Ss>S6. Lower, inner edges of Si -3 moderately sinuous, whereas their
upper, outer margins (adjacent to theca) are notched, rising above calicular edge as exsert lobes. Columella
rudimentary.
Remarks. — Small specimens of F. pavoninum forma coalitum are similar to adult F. politum in many
characters, but can be distinguished by having coarse, slightly convex thecal faces; less acute thecal edges; and less
sinuous inner edges of the S1-3. F. pavoninum is more fully described by Cairns (1989a, 1994).

acute edges but only rarely are edge crests present. Calicular edge smooth. Coralla homogeneously reddish-brown
or white. Pedicel relatively short, 1.5-2. 3 mm in diameter, containing 6 protosepta at the basal disc. Septa
hexamerally arranged in 7 cycles: Si-4>Ss>S6>S7, only the larger coralla having a complete 7th cycle of
384 septa, and one (the largest specimen examined) also having one pair of S8- Si -4 quite narrow near calicular
edge but abruptly widening 10-12 mm lower in fossa, resulting in a very high septal concavity index. Lower, inner
edges of S1-4 highly sinuous. Columella as in F. lamellulosum.

S. D. CAIRNS & H. ZIBROWIUS
REMARKS. — Flabellum magnificum is one of the larger deep-water solitary scleractinians, second in size only
to F. impensum Squires, 1962 and perhaps certain gigantic Desmophyllum dianthus (Esper, 1794) and
Rhizotrochus typus H. Milne Edwards & Haime, 1848. It is easily confused with another large species,
F. lamellulosum Alcock, 1902, but can be distinguished by: its broad corallum (GCD:H = 1.48 average vs 1.05
average for F. lamellulosum)-, its long, uncrested thecal edges (LEL:H = 0.70 average vs 0.48 average for
F. lamellulosum)-, its sinuous Si -4 (SSI = 4.8 average vs 1.13 average for F. lamellulosum)-, and its wide Si -4
(SCI = 14.7 average vs 9.4 average for F. lamellulosum).

Diagnosis. — Corallum highly compressed, resulting in a very low angle of thecal faces (20°-24°), a very
high GCD:LCD (2.0-2.5), and a very narrow fossa. Angle of thecal edges 76°-155°; GCD:H rather low (average =
1.04), indicating corallum to be approximately as tall as wide. Largest specimen known ("Albatross" stn 5313)
28.9 x 67.5 mm in calicular diameter and 54.7 in height, but most specimens examined less than 45 mm in
GCD. Calicular edge smooth. Thecal edges prominently crested, usually as one continuous ridge, but occasionally
forming spurs as in F. lamellulosum. Corallum white to grey, the theca near calicular edge usually discoloured and
slightly corroded as a band 3-5 mm in width that parallels the calicular edge, an indication of an association with a
commensal Lumbrineris polychaete (Zibrowius, SOUTHWARD, & Day, 1975). Pedicel elongate and slender
(1. 5-2.0 mm in diameter), containing 6 protosepta at the basal disc. Septa hexamerally arranged in 6 cycles:
Si-4>Ss>S6, only the largest specimens (GCD > 40 mm) having some S7. Si -4 relatively narrow, their inner
edges almost in contact with those from opposite side across a narrow fossa; columella rudimentary.
Remarks. — Flabellum patens is compared to F. lamellulosum in the account of the latter species and is
more fully described and illustrated by Cairns (1989a, 1994).

Type Locality. — "Siboga" stn 251: 5°28.4'S, 132°02'E (Kai Islands, Banda Sea), 204 m.
Diagnosis. — Angle of thecal edges 130°-240°; angle of planar thecal faces 32°-51°. GCD:H = 0.79-7.05-
1.29, most coralla being higher than wide and having relatively short thecal edges. Largest specimen known
(Karubar stn 70) 49 x 68 mm in calicular diameter and 67 mm in height. Calicular edges smooth. Thecal edges
prominently crested, the crests beginning almost immediately adjacent to pedicel, formed by successive eversions
(spurs) of the calice associated with the 2 principal septa and costae and subsequent retrenchment of the calice edge.
Thecal edges of large specimens may bear 6 or 7 such spurs, some up to 8 mm in height. Well-preserved coralla
homogeneously reddish-brown or white with reddish-brown stripes corresponding to C1-4. Pedicel short and 1.5-
2.1 mm in diameter, containing 6 protosepta in the basal disc. Septa hexamerally arranged in 7 cycles, the last
cycle usually incomplete: Si-4>Ss>S6>S7. Septa relatively narrow, having thickened, straight, lower inner edges.
Columella a well-developed crescent of trabeculae 1.0- 1.5 mm in width.
Remarks. — A comparison of F. lamellulosum to F. magnificum Marenzeller, 1904, is given in the account
of the latter species. F. lamellulosum is also similar to F. patens Moseley, 1881, especially in having a high
corallum (GCD:H = 1.04-1.05 average for both species) and in having prominently crested thecal edges.
F. lamellulosum differs in having a much more open calice with a face angle of 32°-51° and a GCD:LCD of 1.43
(average), compared to 20°-24° and 2.25 (average) for F. patens. The more open fossa also accommodates a more
robust columella in F. lamellulosum. Furthermore, the corallum of F. lamellulosum is less dense and more fragile
than that of F. patens, and does not appear to have the lumbrinerid polychaete symbiont that is so common on the
theca of F. patens.
Petrarcid ascothoracidan galls are present in 2 coralla (MUSORSTOM 1 stn 71 and "Albatross" stn 5273),
evidenced as a characteristic columellar deformation (Fig. 21a).
This species is more fully described and illustrated by CAIRNS (1989a).

DIAGNOSIS. — Angle of thecal edges 90°-136°; angle of thecal faces 30°-45°. GCD:H = 0.98-1.30, indicating
that most specimens are slightly wider than high. Largest known specimen ("Albatross" stn 5392) 22.0 x
36.1 mm in calicular diameter and 29.7 mm in height. Calicular edges smooth. Thecal faces planar, smooth, and
porcellaneous, meeting in sharp, acute edges, which may bear a low thecal crest. Theca of well-preserved coralla
reddish-brown, with stripes of more intense pigmentation associated with C1-3. Pedicel elongate, 1. 0-1.4 mm in
cross section, and broken in all specimens examined, revealing the 6 protosepta. Septa hexamerally arranged in
6 complete cycles: Si-3>S4>Ss>S6 (192 septa). Lower, inner edges of S 1 -3 highly sinuous. Columella
rudimentary.
Remarks. — Flabellum politum is distinguished from other West Pacific species of Flabellum by having a
relatively small corallum; a smooth, lustrous theca; and S1-3 with highly sinuous inner edges. The species is more
fully described by Cairns (1989a).

Type Locality. — "Valdivia" stns 185 and 203: west of Sumatra, 614-660 m.
DIAGNOSIS. — Corallum fragile. Angle of thecal edges 1 15°-150°; angle of thecal faces 64°-80°, resulting in a
very open corallum. Largest known specimen (Karubar stn 63) 39.9 x 53.7 mm in calicular diameter and
28.0 mm in height. Thecal edge crests low (rarely over 2 mm), thin, and continuous, extending from pedicel to
calice. Calicular edge deeply lacerate — a high (up to 6 mm) lancet corresponding to each S]-2 and adjacent pair of
S4 (or the 16 primary septa and adjacent tertiaries). Colour of corallum base white, but theca streaked with broad
reddish-brown stripes corresponding to each Ci-2, and narrower stripes corresponding to each C3. Upper, outer
Si -2 also pigmented. Septa usually hexamerally arranged in 5 cycles: Si-2>S3>S4»Ss, (he 5th cycle usually
incomplete (but see Remarks). Even in larger coralla the S5 are typically rudimentary, occurring in pairs flanking
the S3, not the Si -2, resulting in 72 septa. Columella elongate and rudimentary, formed by the fusion of lower,
inner edges of Si -2.
Remarks. — Cairns (1989a) divided the subgenus Flabellum (Ulocyathus) into 3 groups based on corallum
shape: laterally compressed, bowl-shaped, and constricted. Four similar species belonging to the laterally
compressed group are reported herein: F. deludens, F. marenzelleri, F. japonicum, and F. hoffmeisteri. In addition
to being laterally compressed, these 4 species also have reddish-brown striped theca; pigmented upper outer
margins of the major septa; small edge crests; and small pedicels. Their differences are summarized in Table 2, the
most useful discriminating characters being the nature of the calicular edge, septal symmetry, and the general shape
of the corallum. Among the 4 species, F. deludens has the largest edge angle and the most exsert septal lancets.

The Philippine and Indonesian specimens identified as F. deludens differ from a syntype of that species (ZMB)
and several other Indian Ocean specimens (i.e., "Marion Dufresne" cruise 27, station 4, CP6, west of Ceylon,
1035 m, USNM 82013) in having a smaller pedicel that is elongate, not circular, in cross section. The pedicel
dimensions of the Indian Ocean specimens average 2.34 x 2.46 mm (almost circular), whereas the pedicels of
coralla from the western Pacific are smaller and more elongate in cross section, averaging 1.28 x 2.14 mm
(although the pedicel of at least one specimen from Karubar stn 76 measures 2.15 x 2.40 mm, consistent with

the Indian Ocean specimens). In both cases there are 12 protosepta at the basal disc. The pedicel size and shape
appears to be the only obvious morphological difference between specimens from the 2 regions, and, although this
character may distinguish 2 different species or subspecies, it is interpreted herein by the first author to reflect a
difference in substrate size availability. The second author disagrees with this interpretation, maintaining that the
western Pacific specimens are a separate species different from F. deludens. Support for that hypothesis is
strengthened by the fact that the western Pacific specimens also differ from the Indian Ocean specimens in having a
shallower depth range: mostly less than 350 m vs mostly deeper than 500 m for those from the Indian Ocean.
Cairns (1989a) reported one lot of F. deludens with octameral symmetry, but most of the specimens from the
Karubar stations reported herein have octameral (actually decahexameral) symmetry, consisting of 16 primary,
16 secondary, 32 tertiary, and 32 quaternary septa. The quaternaries occur in pairs flanking the secondary septa, not
the primary, resulting in 96 septa in large coralla. In these specimens the 4 calicular lancets adjacent to the princi¬
pal septa are smaller that the others. These decahexameral specimens are otherwise identical to typical F. deludens.
Flabellum deludens sensu CAIRNS is more fully described and illustrated by CAIRNS (1989a, 1994).

Remarks. — Flabellum marenzelleri is similar to F. deludens, but can be distinguished (Table 2) by having a
denser and more compressed corallum, which is characterised by a lower edge angle and a lower face angle,
resulting in a higher GCD:LCD (1.65-1.75 vs 1.30-1.40 for F. deludens). F. marenzelleri also consistently has
a decahexameral symmetry, whereas only some specimens of F. deludens share this symmetry. F. marenzelleri
also has equal-sized, less exsert calicular lancets, those of F. deludens being dimorphic in size (alternately smaller
and larger) in octameral specimens and much more exsert.
Flabellum marenzelleri is more fully described and illustrated by CAIRNS (1989a).

(MUSORSTOM 3 stn 123) 47 x 62 mm in calicular diameter and 33 mm in height. Corallum very fragile,
campanulate, and laterally compressed, having convex thecal faces that meet in sharp, crested thecal edges. Edge
crests low, usually not extending to calice. Calicular edge serrate, a small (up to 3.5 mm) equilaterally triangular
apex corresponding to each Si-2. Upper part of corallum with reddish-brown stripes corresponding to C1-2; lower

REMARKS. — Among the laterally compressed Flabellum ( Ulocyathus ), F. japonicum is very similar to
F. deludens (Table 2), but can be distinguished by having: smaller, triangular calicular apices resulting in a serrate
(not lacerate) calicular edge; less developed edge crests that do not extend to the calice edge; more convex thecal
faces; a more open calice characterised by a higher face angle; and a lessened thecal pigmentation, often discoloured

stripes associated with primary septa; lower part often discoloured and encrusted by other organisms
(i.e. , brachiopods). Pedicel elliptical in cross section (2. 3-2. 7 mm in greater diameter), short, containing
12 protosepta at the basal disc. Septa arranged in 4 size classes: 16 primary, 16 secondary, 32 tertiary, and a
variable number of quaternary septa. Pairs of quaternary septa first form adjacent to secondary septa and only in
large coralla do they occur adjacent to primary septa. Septa of a 5th size class occur in end-sectors of largest
coralla. Thus, coralla may have 64 septa (no quaternaries), 96 septa (1/2 of quaternaries present), 128 septa (a full
4th size class), or over 128 septa, if some septa of the 5th size class are present.
REMARKS. — Among the laterally compressed species of this subgenus, F. hoffmeisteri is similar to
F. japonicum but is distinguished by its decahexameral (x 1 6) septal symmetry; its moderately serrate calicular
edge and its lower face angle (angle between thecal faces) (Table 2). It differs from the other decahexamerally
symmetrical species, F. marenzelleri and some F. deludens, in having a much less jagged calicular edge, convex
thecal faces, virtually no edge crests, and a larger face angle.

calicular diameter and 42 mm in height. Thecal edge crests extend from pedicel to calicular edge. Calicular edge
highly lacerate, but rarely well preserved because of extreme fragility. Pedicel circular to slightly elliptical in cross
section, up to 3.4 mm in greater diameter, short, and containing 12 protosepta at the basal disc. Thecal faces rough
in texture. Corallum reddish-brown, except for pedicel and edge crests, which are white. Septa hexamerally arranged
in 5 cycles: Si-3>S4>Ss (96 septa). Fossa deep and narrow.
Remarks. — Flabellum messum is unique in this region within the subgenus in having a "constricted"
corallum (Cairns, 1989a). It is further distinguished by is reddish-brown theca (no stripes); short, stout pedicel;
and roughly textured theca. Flabellum messum is more fully described and illustrated by CAIRNS (1989a, 1995).

DESCRIPTION. — The single Philippine specimen measures 24.9 x 32.0 mm in calicular diameter, 21.8 mm in
height, and is curved 45° in plane of LCD. Its edge angle is 48° and its face angle is also approximately 48°, but
the lower 6 mm of the corallum has a much higher edge angle and lower face angle than the upper part. Thecal
faces convex, in lower half of corallum, meeting in an acute angle at thecal edges; in upper half thecal edges
rounded. Calicular edge lacerate, each Si -2 and adjacent pair of S4 forming a lancet about 3 mm in height. Pedicel
circular, 1.6- 1.7 mm in diameter, containing 6 protosepta at basal disc. Corallum white with very faint reddish-
brown stripes associated with C1-2 and upper, outer edges of S 1.2.
Septa hexamerally arranged in 5 cycles, the 5th incomplete: Si-2>S3>S4>Ss; pairs of S5 occur only adjacent to
S3 (not Si -2), resulting in 72 septa. Inner septal edges sinuous, the lower edges of Si -2 contributing to an elongate
columella.
A well-preserved specimen from the New Zealand region (“ Tangaroa " stn G3) is larger (29.8 x 33.6 mm in
calicular diameter and 31.1 mm in height), curved 90°, and has more septa, i.e., 90. It is otherwise similar to the
Philippine specimen.
Remarks. — The specimens reported above are similar to F. moseleyi Pourtales, 1880, which is the only
other species in the subgenus known to have a secondarily free, curved corallum. It differs in having fewer septa at
a corresponding GCD (the 5th cycle of F. moseleyi is complete at a GCD of about 30 mm) and in its method of
septal insertion, i.e., S4 pairs insert adjacent to S3 before adjacent to Si -2. F. moseleyi also has much more
prominent (up to 6 mm) and more slender, triangular calicular lancets. F. moseleyi is known only from the
Caribbean and eastern Gulf of Mexico, depth 216-1097 m (C.AIRNS, 1979). Although the specimens reported above
may represent an undescribed species, not enough specimens are available to properly describe it or definitively
distinguish it from F. moseleyi.

DIAGNOSIS. — Corallum laterally compressed, the slightly convex thecal faces meeting at acute, carinate
edges; edge crests small and present only on lower half of corallum. Angle of thecal edges changes from 90°-130°
to 55°-75° 12-15 mm above the base; angle of thecal faces changes from 61°-73° to 29°-36°. Also at this height the
4 lateral Ci are prominently ridged. Largest known specimen (MUSORSTOM 1 stn 47) 32.3 x 50.7 mm in calicular
diameter and 42.2 mm in height. Calicular edges serrate, each Si -2 producing a tall (up to 4 mm) triangular lancet.
Pedicel elliptical in cross section (2.0-2. 1 mm in greater diameter), short, containing 12 protosepta at the basal
disc. Septa hexamerally arranged in 5 cycles: Si-2>S3>S4>Ss (96 septa).
Remarks. — This is the 2nd report of F. sexcostatum, the MUSORSTOM specimens being collected close to
the type locality.
Flabellum sexcostatum was not placed by CAIRNS (1989a) in a species group within the subgenus Flabellum
(Ulocyathus) because it is intermediate in shape between the laterally compressed and bowl-shaped groups. The
species is more fully described and illustrated by Cairns (1989a).

Calice slightly elliptical: GCD:LCD = 1.05-1.30. Thecal edges and faces convex. No edge crests, but the 6 Ci are
slightly ridged on lower half of corallum. Calicular edge serrate, a short (up to 3.5 mm) equilaterally triangular
apex corresponding to each Si-2, but generally damaged because of high fragility. Pedicel circular in cross section
(2. 1-2.3 mm in diameter), short, containing 12 protosepta at the basal disc. Theca smooth, light grey in colour.
Septa hexamerally arranged in 5 cycles, the 5th cycle rudimentary and sometimes missing: Si-2>S3>S4»Ss.
Fossa deep and narrow.
Remarks. — Flabellum conuis is unique in this region within the subgenus in having a bowl-shaped or
campanulate corallum (Cairns, 1989a) and an almost circular corallum. Its deep range also distinguishes it from
other Flabellum in the region. It is more fully described by Cairns (1989a).

corresponding to each Si-2. Pedicel thickened by asymmetrical development of 4 contiguous, hollow rootlets,
2 flanking each side of the 2 principal septa. These rootlets grow downward, completely encircle the base, and
fuse, forming a V-shaped junction near the base of opposite thecal side. Theca smooth, streaked with reddish-brown
pigment corresponding to the Ci-2, although rootlets and pedicel remain white. Septa hexamerally arranged in
5 complete cycles: Si-2>S3>S4>S5-

TYPE LOCALITY. — Singapore, South China Sea (depth not given).
Diagnosis. — Corallum conical (turbinate); calice elliptical (GCD:LCD = 1.20-1.45); calicular margin
smooth. Largest Philippine specimen ("Albatross" stn 5357) 40.1 x 57.2 mm in calicular diameter and 38.3 mm
in height. Pedicel narrow (1.0- 1.5 mm in diameter) and not reinforced; however, several cycles of discrete, hollow
rootlets (rootlet diameter 1. 0-2.5 mm), extend from lower corallum to substrate, firmly anchoring the corallum.
Corallum white. Septa hexamerally arranged in 6 cycles, the 6th complete only in large specimens:
Si-2>S3>S4>S5>S6. Upper, outer margin (near calice) of Si-3 quite narrow, but upper axial edge of same septa
project as broad lamellae into fossa.
Remarks. — Rhizotrochus typus is easily distinguished from all other flabellids in the Philippine/Indonesian
region by having numerous, discrete (i.e., free standing, not contiguous with corallum) rootlets. One large
specimen at the BMNH (1950.1.11.630) from Mauritius measures 108 mm in GCD. The species is more fully
described and figured by CAIRNS (1989a).
One unusual specimen of Rhizotrochus from DEKI stn 25 (NNM 23096) deserves special note. It is 13.3 x
19.1 mm in calicular diameter, 1 1.5 mm in height, and has 96 septa. It differs from other Rhizotrochus in having
a truncated base with a basal scar of 5.2 x 8.5 mm in diameter, which suggest that transverse division occurred. It
also has a polygonal calicular cross section, each C| being slightly ridged, rootlets occurring only in series on the
Ci. The presence of transverse division in Rhizotrochus is unexpected, since the upper part of the corallum is held
stationary by numerous rootlets, which should not even allow division to occur. Nonetheless, one specimen is
known with this character combination (Figs 22 d-e).

Diagnosis. — Corallum highly laterally compressed (GCD:LCD = 2.4-3.4); calicular edge smooth. Largest
known specimen (Deki stn 59) 25 x 73 mm in calicular diameter. Pedicel quite narrow (1.2- 1.5 mm in diameter),
but attachment reinforced by 2 compressed, massive (4-5 mm in diameter) rootlets, one originating from each
calicular edge and firmly anchored to the substratum. Corallum light reddish-brown, young ones having a more
intense Ci-2 pigmentation. Septa hexamerally arranged in 6 to 7 cycles (Si-4>Ss>S6>S7), but even largest
specimens with incomplete 7th cycle. Fossa deep and narrow; columella rudimentary.
Remarks. — The second author disagrees with the first in placing "R." flabelliformis in this genus. He
considers that it is not a true Rhizotrochus , not being attached by circles of adventitious, cylindrical rootlets. The
general morphology is closer to that of a species of Flabellum (Flabellum), the anchoring pair of compressed
opposite thecal edge eversions, by position and formation, being similar to irregular spurs on edge crests of
Flabellum ( Flabellum ) and to spines on edge crests of Truncatoflabellum. The use of these eversions for
attachment is a qualitative leap with respect to edge crest formation in those two other taxa.
This species is more fully described and illustrated by Cairns (1989a, 1994).

Description. — Corallum conical (turbinate), with a basal angle of 38°-42° and a circular calice. Largest
known specimen (MUSORSTOM 1 stn 63) 17.5 mm in calicular diameter and 19.6 mm in height, with a robust
pedicel 7.1 mm in diameter (PD:GCD = 0.41). Corallum attached exclusively through the base of its pedicel.
Theca usually heavily encrusted with bryozoans, foraminifera, serpulid tubes, and sponges. Unencrusted theca
white, bearing fine horizontal epithecal striae. Calicular margin smooth, rising as a thin lip as much as 1.5 mm
above upper, outer septal edges.
Septa hexamerally arranged in 4 complete cycles (48 septa): Si>S2>S3>S4. Si thick, their inner edges vertical
and straight, extending to columella; their peripheral edges meet the theca below the calicular margin, their upper
edges rise slightly above calicular edge. S2 similar to Si in shape, but slightly less exsert and narrower, also
attaining the columella. S3 about 1/2 width of S2, each bearing a small paliform lobe that merges with the
columella. S4 rudimentary. Fossa of moderate depth, containing a well-developed columella consisting of
12-17 papillose elements.
Remarks. — The original description of G. philippinensis was based on a type series consisting of the dead,
poorly-preserved holotype; a juvenile corallum; and a damaged pedicel of a 3rd specimen. The 2 specimens reported
above are larger and better preserved, permitting the observation that the species attains 4 full cycles of septa and
that it attaches exclusively through the base of its pedicel, not laterally.

Gardineria philippinensis is similar to G. hawaiiensis Vaughan, 1907, in shape and size but differs in attaining
a full 4th cycle of septa and in having a robust columella. It differs from Gardineria sp. A (reported by Cairns,
1995 from the Chesterfield Islands, Lord Howe Seamount Chain, and Norfolk Ridge, depth 291-378 m) by its
robust columella.
DISTRIBUTION. — Philippines : Lubang Island; Ragay Gulf, Luzon; Iligan Bay, Mindanao; 192-494 m.
Indonesia: Arafura Sea (southeast of Tanimbar Islands); 222-226 m.

Type Locality. — "Bibb" stn 22: 24°14’20"N, 80°59'40"W (Straits of Florida), 692 m.
DESCRIPTION (larger specimen). — Corallum elongate-conical: 20.2 mm in length and 11.2 mm in calicular
diameter. Corallum attached to substratum by pedicel as well as theca on one side all along from pedicel to calice.
Theca exteriorly eroded and encrusted with bryozoans. Although collected alive, specimen resembles a fossilized
corallum. Theca dense, up to 1.5 mm thick, extending as a robust lip about 1.3 mm above upper, outer septal
edges.
Septa decamerally arranged in 3 size classes: 10:10:20 (40 septa). Primary septa nonexsert, having straight,
vertical inner edges that join the columella low in fossa. Secondary septa similar in shape, about 2/3 width of a
primary, each secondary bearing a discrete paliform lobe about 0.8 mm in width. Tertiary septa narrow, about
1/2 width of a secondary, having finely dentate inner edges and extending only about 6 mm from calicular edge.
Columella papillose, composed of 13 cylindrical (0.5 mm in diameter), granular elements.
The smaller of the 2 specimens is a juvenile only 5. 1 mm in calicular diameter and contains only 30 septa.
Remarks. — This is first report of G. paradoxa outside the western Atlantic, where it is known from the
Greater and Lesser Antilles (Cairns, 1979). Comparison of the Karubar specimens to those from the Antilles
shows no significant differences; a specimen from Barbados (Fig. 21 g) is particularly similar to the large
Karubar specimen.
Gardineria paradoxa is distinguished from the other species in the genus by having decameral septal symmetry
and a strong secondary lateral attachment.
Distribution. — Indonesia: Banda Sea (Kai Islands); 285-323 m. Elsewhere: western Atlantic (Antilles);
91-700 m.

Diagnosis. — Corallum elongate-conical, straight, robust, and slightly flared distally; calice usually highly
elliptical (GCD:LCD = 1.3-1. 7). Pedicel thickened with concentric layers of dense stereome, its diameter up to
55% of GCD. Corallum rarely over 25 mm in GCD or 43 mm in height; white. Septa hexamerally arranged in
5 cycles according to formula: Sl-2>S3»S4>Ss. S5 begin to appear at a GCD of 9-10 mm and the cycle is
usually complete at a GCD of 15-17 mm. Si -2 highly exsert, producing a lacerate calicular margin, but

diagnosis. — Corallum elongate-conical and straight, having a pedicel thickened with layers of dense
stereome up to a diameter of 10 mm; theca of upper part of corallum relatively thin and delicate. Largest known
specimen (MUSORSTOM 1 stn 63) 29.5 x 44 mm in calicular diameter and 48 mm in height, with a pedicel
diameter of 9.0 mm. Corallum Oared distally, having an elliptical calice: GCD:LCD = 1.25-1.50. Upper corallum
usually light reddish-brown, occasionally white; lower corallum usually white. Septa hexamerally arranged in
5 complete cycles: Si-2>S3>S4>S5. All septa exsert to some degree, producing a serrate calicular edge.
REMARKS. — The figured syntype of Desmophyllum alabastrum Alcock, 1902 ("Siboga" stn 105) is missing
trom the ZMA; however, ALCOCK's (1902c) illustration appears to show the lower half of a Javania. In 1994, a
large, previously unidentified and well-preserved specimen of J. lamprotichum (35.8 x 27.6 mm in calicular
diameter, 8.3 mm pedicel diameter), was found at the ZMA, also from "Siboga" stn 105. Although not the
illustrated specimen and probably not even seen by ALCOCK, this is considered to be indirect evidence that
ALCOCK's (1902c) figured specimen of D. alabastrum might have been Javania lamprotichum. The other syntype
of D. alabastrum, from "Siboga " stn 95 (ZMA Coel. 1 252), appears to be a Thalamophyllia.
Javania lamprotichum differs from J. insignis Duncan, 1876, in having a larger, more delicate, flared corallum;
usually a pigmented, noncostate theca; and more prominent S4-5.
Coralla of 3 lots (MUSORSTOM 1 stns 63, 65, 2 stn 53) contain 1 or more borings of acrothoracican cirripedes.
Distribution. — Philippines: Lubang Island; Sulu Sea (Sulu Archipelago); 191-842 m. Elsewhere: Kermadec

in calicular diameter and 33.8 mm in height, with a pedicel diameter of 7.2 mm. Upper part of corallum smooth
and porcellaneous, a light purple-grey in colour; lower corallum superficially eroded, discoloured, and encrusted.
Septa hexamerally arranged in 4 cycles: Si»S2>S3>S4- Si extremely exsert (up to 6.5 mm), having vertical,
straight inner edges. S2 1/2 as exsert but almost as wide as Si, having slightly sinuous inner edges. S3 only
0.5- 1.5 mm exsert, about 3/4 width of an S2, also having slightly sinuous inner edges. S4 not exsert (not even
reaching the top of the calice), about 1/3 width of an S3, having slightly sinuous inner edges. Fossa deep and
narrow.
Remarks. — The Karubar specimens reported above resemble the widespread species J. cailleti (Duchassaing
& Michelotti, 1864), but differ in having more exsert Si (much more exsert than their S2), and in having a purple-
grey pigmentation. Whereas some specimens of J. cailleti have highly exsert septa (e.g., holotype of D. nobile
Verrill, 1885; USNM 82016 from Lydonia Canyon, NW Atlantic), the Si of most specimens rarely exceed 4 mm
in exsertness, and in all cases S2 equal in size to SI. Furthermore, the corallum of J. cailleti is always white,
whereas the Karubar specimens are pigmented.
Descriptions and illustrations of J. cailleti are found in CAIRNS (1979, 1982, 1991) and ZIBROWIUS (1980).
It is a widely distributed species known from the Atlantic, Pacific, and Indian Oceans at depths of 86-2165 m.

Type Locality. — Singapore, South China Sea, 3-6 m.
Description. — Anthocyathus highly compressed (GCD:LCD up to 3.65), the planar thecal faces meeting in
rounded, but narrow, edges that bear 1 pair of edge spines about 4 mm above basal scar. Angle of thecal edges
57°-165°; angle of thecal faces quite low, 20°-31°. Largest known specimen (Karubar stn 65) 14.5 x 52.8 mm in
calicular diameter. Basal scar of most Indonesian specimens reported herein small, only 3. 2-5.0 mm in greater
diameter. Calicular margin strongly arched, smooth. Corallum white but often encrusted with bryozoa,
foraminifera, serpulids, and calcareous algae.
Large specimens (GCD > 45 mm) have septa hexamerally arranged in 6 cycles (Si-4>S5>S6, 192 septa), often
with additional pairs of S7, but smaller specimens have only 40, 42, 44, or 46 primary septa, a corresponding
number of secondaries, and twice that number of tertiary septa, resulting in coralla of 160, 168, 176, or 184 septa.
Si -4 (primary septa) narrow, notched near the calicular margin, and slightly concave midway down fossa. Lower,
inner edges of S1-4 quite thick and fused to columella. S5 (secondary septa) about 3/4 width of S1-4, not attaining
the columella. S6 (tertiary septa) about 1/2 width of S5, extending only a short distance from calicular edge. When
present, S7 (quaternary septa) are paired but are quite narrow and short. Fossa deep and elongate, containing a well-
developed columella about 1.4 mm in width.
Remarks. — Specimens from "Galathea" stns 330 and 501, and Haeckel's specimen are typical
T. spheniscus. with the large basal scar as in the type series. The other specimens reported above differ in having a
much smaller basal scar: 3. 2-5.0 mm in greater diameter vs 10.0-1 1.2 mm for the syntypes. The specimens appear
otherwise consistent in all characters, and thus scar diameter is considered by the first author to be variable in this
species. The second author is highly skeptical about identifying these small-scar specimens as T. spheniscus. His
general experience is that the size of the basal scar, reflecting the size at which transverse division occurred, is
standard in species of Truncatoflabellum and other transversely dividing species. T. spheniscus is distinguished
from most other species in the genus by its elongate, narrow calice and its distinctively shaped Si -4.
Distribution. — Indonesia: Arafura Sea (south of Tanimbar Islands); Timor Sea; Savu Sea; Sunda Strait,
Java Sea; 30-174 m. Elsewhere: Japan (Shikoku; Korea Strait; Honshu; northern Ryukyu Islands); Formosa Strait;

Type Locality. — Philippines (depth not given).
Diagnosis. — Anthocyathus compressed (GCD:LCD = 1. 8-2.6), the slightly convex thecal faces meeting in
rounded edges that usually bear 1 pair of edge spines directly adjacent to basal scar. Angle of thecal edges 45°-53°;
angle of thecal faces 28°-31°. Largest known specimen (KH72-1-29) 16.5 x 41.0 mm in calicular diameter and
25.5 mm in height, with a basal scar of 6.2 x 14.3 mm. Calicular margin of septal faces arched; corallum white.
Septa of most specimens hexamerally arranged in 5 complete cycles: Si-3>S4>Ss (96 septa); however, large
specimens have additional primary septa equal to Si -3 in size. Shape of septa as described for T. spheniscus , but
inner edges of Si -3 highly sinuous.
Remarks. — Although not noted by Cairns (1989a), T. aculeatum is similar to T. spheniscus (Dana, 1846),
especially in septal shape, and both species have been collected from the same stations. T. aculeatum is
distinguished by having a lower edge angle and higher face angle and thus a smaller GCDiLCD; a smaller
corallum; and less septa, most specimens having only 5 cycles (96 septa). The species is more fully described by
Cairns (1989a).

1.6- 1.9. Largest known specimen (holotype of F. elegans ) 16.5 x 32.3 mm in calicular diameter and 21.7 mm in
height. Most coralla bear 3 pairs of thecal edge spines: the lowest pair directly adjacent to basal scar and curved
downward; the middle pair directed horizontally; and the uppermost pair directed slightly upward. Spines often quite
long (up to 10 mm) and strongly compressed, having wide triangular bases. Basal scar up to 6 mm in greater
diameter. Calicular margin serrate, a small apex corresponding to each of the 20-24 primary septa. Upper,
peripheral edges of primary septa and corresponding costae, reddish-brown. Septa arranged in 3 size classes:
20-24:20-24:40-48, resulting in 80-96 septa. Columella well developed.
Remarks. — Truncatoflabellum candeanum is distinguished from other species by its multiple pairs of long,
flattened edge spines; and its scalloped calicular margin. It is more fully described by Cairns (1989a).

Remarks. Truncatoflabellum irregulare is distinguished from T. incrustatum by having irregular septal
symmetry and only 3 (not 4) size classes of septa. It also has a white (not dark) theca, a smaller basal scar, and
a septal notch on each primary septum.
The specimens reported as Flabellum irregulare by ALCOCK (1902c) ("Siboga" stns 49a, 253) were re-examined
and found to be juvenile specimens of an unknown species, not T. irregulare. T. irregulare is more fully described
and illustrated by Cairns (1989a).

Diagnosis. — Angle of thecal edges 57°-138°; angle of thecal faces 31°-62°. Thecal faces virtually planar,
meeting in straight, nonspinose, noncrested, acute thecal edges. Largest known specimen (Karubar stn 71)
34.4 x 61.7 mm in calicular diameter and 48.2 mm in height. Basal scar elliptical but variable in size, greater
diameter 6.8 to 14.5 mm. Corallum white or uniformly reddish brown, the theca of most specimens being worn
and discoloured. Septa hexamerally arranged in 6 cycles (Si-3>S4>Ss>S6, 192 septa), the 6th cycle beginning to
appear at a GCD of 26-30 mm. Columella well developed, consisting of a robust fusion of the lower, inner edges
of S i-3, and being about 2.1 mm in width.
REMARKS. — Among the western Pacific species, T. paripavoninum is distinguished by having a large
corallum; nonspinose and noncrested thecal edges; and by occurring in relatively great depths. The diagnosis above
is based on the anthocyathus stage, only one specimen (Karubar stn 56) being an anthocaulus. The species is
more fully described and illustrated by CAIRNS (1989a, 1995).
Four specimens from Karubar stns 56 and 71 serve as the substratum for a stalked suberitid sponge
(? Rhizaxinella, identified by K. RUTZLER) (Fig. 22 f). The slender stalk (up to 60 mm long and 3 mm in
diameter) supports a "head" about 20 x 10 mm in size. The stem of the sponge is attached to the theca of the
living coral just below the calicular edge.

DIAGNOSIS. — Angle of rounded thecal edges 37°-59°; angle of thecal faces 18°-34°. GCD:LCD = 1.4-1. 8.
Most anthocyathi have 2 pairs of thecal edge spines, the lowermost pair 3-4 mm above the basal scar and the upper
pair usually quite short, each of these upper spines with a broad, flat, triangular base. Largest Philippine specimen
(". Albatross " stn 5289) 13.4 x 23.0 mm in calicular diameter and 31.4 mm in height. Calicular margin arched and
smooth. Basal scar relatively small, 4-5 mm in greater diameter. Well-preserved specimens have reddish-brown
thecal stripes associated with the 20 primary septa. Septa arranged in 3 size classes (20:20:40 = 80 septa), some
pairs of tertiaries occasionally missing. Primary septa gracefully arched near calicular edge, having sinuous inner
edges. Ternary septa rudimentary, much smaller than the secondaries. All septa widely spaced.
Remarks. — This species is more fully described by Cairns (1989a, 1994).

stn 5179) 2.9 x 3.9 mm in calicular diameter and 6.8 mm in height, with a greater scar diameter of 3.4 mm. In
addition to transverse division, this species also undergoes rejuvenescence, resulting in elongate coralla ol varying
diameters. Thecal faces convex; thecal edges rounded, each edge bearing 1-6 strongly downcurved spines. Theca
porcellanous, well-preserved specimens brown in colour, with more intense pigmentation in stripes adjacent to

Remarks. — Truncatoflabellum phoenix is distinguished from T. pusillum Cairns, 1989, and T. dens
(Alcock, 1902), species also having small coralla, by having: parallel thecal edges and faces that result in a basal
scar almost as large as the calice; usually only 24 septa; a more robust columella; an elongate corallum
characterized by multiple rejuvenescence events; and strongly downcurved thecal edge spines. The species is more
fully described and illustrated by CAIRNS (1994, 1995).

Type Locality. — 11°36'N, 121°43'E (Sulu Sea west of Panay), 120-122 m.
ETYMOLOGY. — This species is named for Theodor MORTENSEN, who made many collections of Indo-West
Pacific fauna, including this species from the Java Sea.
DESCRIPTION. — Anthocaulus: Angle of rounded thecal edges 49°-61°; angle of convex thecal faces 23°-31°.
One pair of slender edge spines occurs 4-6 mm above the pedicel, these spines being elongate (up to 7.5 mm) only
on small specimens; on larger specimens these delicate structures are always broken. Base of thecal spines broad
and compressed. Pedicel circular and quite small (0.8- 1.1 mm in diameter), sometimes revealing the 6 protosepta.
Largest anthocaulus (MUSORSTOM 3 stn 131) 10.1 x 17.1 mm in calicular diameter and 19.5 mm in height.
Calicular margin of thecal faces slightly arched and smooth; GCD:LCD = 1.65-1.85. A thin reddish-brown thecal
stripe corresponds to each Si-3, a thinner stripe to each S4-5. Most anthocauli from MUSORSTOM 3 stn 131 tend
not to divide transversely after the edge spines are formed, continue to grow up to 18 mm in height, and have
64 septa; however, anthocauli from all other stations rarely exceed 7 mm in height before transversely dividing or
forming an incipient transverse fracture line.
Septa hexamerally arranged in 5 cycles (Si-3>S4>Ss), pairs of S5 present only in large anthocauli (up to
64 septa). S1-3 nonexsert, attenuate, gracefully concave near calicular edge, having highly sinuous lower, inner
edges. S4 about 1/2 width of S1-3, having straight inner edges. S5 1/3 to 1/2 width of the S4, having slightly
dentate inner edges. S5 originate in a progression from half-systems adjacent to the principal septa towards centre
of thecal face. Fossa deep and elongate; columella rudimentary.
Anthocyathus: One of the largest anthocyathi (holotype) measures 12.3 x 22.5 mm in calicular diameter and
16.9 mm in height, with a basal scar of 3.5 x 7.1 mm. Angle of thecal edges and faces similar to that of
anthocaulus. One, occasionally 2, pair(s) of edge spines, the lowermost pair occurring within 1 mm of basal scar.
Basal scar elliptical, 6.3-7. 3 mm in greater diameter. Theca pigmented as in anthocaulus.
Septa of anthocyathus hexamerally arranged in 5 cycles (Si-3>S4>Ss) as in anthocaulus, but in most
anthocyathi the 5th cycle is complete (96 septa). S 1-3 notched near theca, rising slightly above calicular margin
toward centre of fossa. Inner septal edges highly sinuous. S4 1/3 to 2/3 width of Si -3, but having less sinuous
inner edges. S5 rudimentary. Columella well developed, about 1 .3 mm in width.
Remarks. — In many ways the anthocaulus of T. mortenseni is similar to that of T. zuluense Cairns, 1993,
the corallum of both species often resisting transverse division after the basal pair of edge spines has formed.
T. mortenseni differs from T. zuluense in having: a larger edge angle; a smaller diameter pedicel; Si -3 that are
equal in size (versus Si-2>S3 in T. zuluense)-, and usually having more septa, i.e., 56-80 vs 48-56 for T. zuluense.
The anthocyathus of T. mortenseni is distinguished (Cairns, 1989a: table 6) by the combination of having a
septal formula of Si-3»S4>Ss and having 1 or 2 pairs of thecal edge spines.
Many live specimens of Truncatoflabellum mortenseni from Bali Strait, 50-70 m (MORTENSEN's stn 5, 6, 8)
were the substrate of the inarticulate disciniscid brachiopod Discradisca Stella (Gould) (det. A. LOGAN, 1993) and
the hipponicid prosobranch gastropod Malluvium sp. (det. A. Waren, 1993). Both epibionts were localized
generally near the calicular edge of live corals, Malluvium sp. exceptionally also on a dead coral.
Distribution. — Philippines-. Verde Island Passage; Tablas Strait; Sulu Sea west of Panay; 122-130 m.
Indonesia: Banda Sea (Kai Islands); Bali Sea and Bali Strait; 50-156 m.

ETYMOLOGY. — The species name angustum (Latin angustus, slender, thin) alludes to the highly compressed
(slender) calice of this species.
DESCRIPTION. — Anthocyathus: Thecal faces flat to slightly convex, meeting in sharp edges that bear 3 or
4 pairs of slender, delicate edge spines. Angle of thecal edges 28°-52°; angle of thecal faces 17°-22 . Basal scar
relatively small: 1. 8-2.5 x 2.7-3. 3 mm. Largest specimen (holotype) 6.1 x 14.0 mm in calicular diameter and
10.8 mm in height, with a basal scar diameter of 2.1 x 3.1 mm. Calicular margin of septal faces slightly arched
and smooth; GCD:LCD = 1.85-2.31. Theca white to slightly reddish-brown.
Septa hexamerally arranged in 5 cycles, the last cycle never complete: Si-2>S3»S4>Ss. Most specimens have
only 4 pairs of Ss, 1 pair in each half-system adjacent to the 2 principal septa, resulting in a total of 56 septa.
Si-2 nonexsert, attenuate, having very sinuous inner edges that fuse to the columella lower in fossa. S3 7/10-9/10
width of S1-2 and usually less sinuous. S4 1/4- 1/3 width of the S3; S5 rudimentary, 1/2 width of S4. Fossa deep
and narrow, the columella being about 0.8 mm in width.
Anthocaulus: Only one unequivocal anthocaulus is known (MUSORSTOM 3 stn 130), the anthocyathus having
become detached during this study. This anthocaulus is 1.3 mm in pedicel diameter, 2.7 mm in height, and has a
GCD of 3.25 mm. It bears no thecal spines and has 24 septa arranged in 2 size classes: S i-2>S3-
Remarks. — Truncatoflabellum angustum has a septal number and arrangement similar to T. zuluense Cairns,
1993, and T. gardineri Cairns, 1993, both from the southwest Indian Ocean. T. angustum differs from both in
having a more elongate calice (higher GCD:LCD). It also differs from T. gardineri Cairns, 1993, in having a
smaller basal scar, and having thecal edge spines, not crests. It differs from T. zuluense in consistently severing its
anthocyathus from its anthocaulus.
Several specimens of T. angustum were reported and figured by CAIRNS (1995) as the anthocyathus stage of
T. dens, both species having been found at the same station and being similar in size and colouration. T. dens
(Alcock, 1902) is distinguished from T. angustum by having a bimodal edge angle and tending to have 32 septa vs
56 septa in T. angustum.

Type Locality. — "Siboga" stn 212: 5°54.5'S, 120°19.2'E (Flores Sea), 462 m.
Diagnosis. — Corallum cylindrical, with virtually parallel thecal faces and parallel, rounded thecal edges. No
edge spines. Calice elliptical, the specimen reported herein 9.2 mm in GCD, with a basal scar of approximately
the same size as the calice. Shape of calice often asymmetrical, one thecal face being slightly less curved and
having more septa than the other face. Theca white, engraved with shallow, vertical striae that delimit wide, flat
costae. Septa hexamerally arranged in 4 cycles (Si-2>S3>S4), the 4th often incomplete, resulting in 40 septa. All
septa relatively thin and widely spaced. Fossa deep and elongate, containing a well-developed, elongate trabecular
columella that occupies medial 1/3 of fossa.
Remarks. — ALCOCK (1902b, c) chose a relatively small specimen ("Siboga" stn 212) as the holotype of this
species, not even mentioning the larger, better-preserved specimen reported herein from "Siboga" stn 297. It is
possible that Alcock did not have access to the entire "Siboga" collection when he wrote his report on the corals
from that expedition, as many other large, well-preserved "Siboga" specimens are reported herein for the first time.
Placotrochides scaphula is more fully described by Cairns (1989a, 1994) and Cairns & Parker (1992).

Type Locality. — Bohol near Pandonon, Philippines, 55 m.
Diagnosis. — Corallum unattached, straight to slightly curved, and compressed, the elliptical calice having a
GCD:LCD range of 1.15-1.55. Corallum edges sharp and slightly keeled, small buds asexually generating from the
edges. Once a bud detaches, a small irregularity may persist on thecal edge of parent. Because predominant mode of
reproduction appears to be by asexual budding, the base of most specimens is usually an open fracture about 1 mm
in diameter, revealing the 6 protosepta. Most specimens small, rarely over 10-11 mm in GCD, but ZIBROWIUS
(1985) reported a specimen 20 mm in GCD, and another listed above (SlPHlLEXP stn 78-T14) measures
14.2 x 21.6 mm in calicular diameter and 33.1 mm in height. Septa hexamerally arranged in 4 cycles in
a Pourtales plan, only larger specimens (GCD>19 mm) having pairs of S5, the largest specimen having 88 septa.
S 1-2 independent, slightly exsert, and relatively narrow, with smooth inner edges. Remaining septal cycles have
laciniate inner edges. Columella well developed and elongate, flat on top, and fused to lower, inner edges of the

Remarks. — Few specimens have been collected with attached buds, the buds apparently detaching at a
relatively small size.
This species has been found to host the petrarcid ascothoracidan Zibrowia auriculata Grygier, 1985, the gall of
which causes the columella to become larger and more porous than normal (ZIBROWIUS & Grygier, 1985).

like the Si -3. Fossa deep and spacious. Columella small in relation to size of corallum, composed of a narrow
(about 1.7 mm wide), elongate field of many, small (0.15 mm diameter) papillae that are weakly swirled in a
clockwise vortex. Columella low, but discrete and slightly convex.
Remarks. — Balanophyllia desmophyllioides is distinguished from other species by its highly arched calice;
its coarsely dentate S1-3 and S5; and the fusion of each pair of S5 high in the calice before their common S4. Some
of the specimens reported above are much larger than the holotype and subsequently reported specimens (Cairns,
1984), the holotype being only 15.0 mm in GCD and somewhat irregular in shape.
In our opinion, the species name was originally incorrectly formed, being derived from the root
Desmophyllum, and thus should be desmophylloides. However, according to the 1CZN (Article 32dii) the original
spelling cannot be changed.

Description. — Corallum elongate-conical, with a slightly compressed calice (GCD:LCD = 1.1 -1.3). Two
growth forms occur: one having a straight, firmly attached (PD:GCD = 0.32-0.46) corallum, characteristic of the
type series; the other a curved (ceratoid), usually free corallum (PD:GCD = 0.12-0.21). The straight form has a
broadly encrusting base, whereas the curved form is either unattached or attached to a small object, such as a small
gastropod shell. The differences in growth form may simply be the result of the kind of substratum available on
which to settle, the costal and calicular characteristics being otherwise the same. Largest straight form
( usorstom 3 stn 105) 19.5 x 23.1 mm in calicular diameter and 34.6 mm in height, with a pedicel diameter of
T9 mm; largest specimen of ceratoid form (" Albatross " stn 5313) 22.9 x 27.5 mm in calicular diameter and
36.9 mm in height, with a pedicel diameter of 4.5 mm. Costae flat, 0.5-0.7 mm in width, and well defined by
deep, mow (about 0.1 mm) intercostal striae. Costae a reticulum covered by small, irregularly-shaped granules.
Lateral faces of costae also bear small granules that project into intercostal striae. Usually no epitheca, but when
present, restricted to lower pedicel.

Septa hexamerally arranged in up to 5 cycles: the 3rd (24 septa) complete at a GCD of about 8 mm; the 4th (48
septa) at 1 1-12 mm GCD; half of the 5th cycle (72 septa) at a GCD of 15-19 mm; and a full 5th cycle (96 septa)
at about 24 mm GCD. Si -2 essentially the same size, only slightly exsert, having smooth, vertical inner edges
that extend to the columella. S3 about 2/3 width of S1-2, also having smooth inner edges, which do not reach the
columella. In a corallum with 72 septa, which is the most common complement, the quarter-systems adjacent to
each S2 contain only 1 S4, whereas the quarter-systems adjacent to the Si contain 3 septa: 1 S4 and a pair of S5.
S4 adjacent to S2 are approximately the same size as the S5 adjacent to Si in the same half-system, the inner edges
of these 2 septa fusing near the columella. Inner edges of higher cycle septa also smooth. Fossa of moderate depth,
containing a well-developed, convex (discrete), elongate columella composed of many short lamellar elements
swirled in a clockwise direction. In some specimens the inner edges of the 4 lateral Si constrict the elongate
columella into 3 connected nodes.

DESCRIPTION. — Corallum cylindrical, straight, and firmly attached through a thick pedicel (PD:GCD =
0.70-0.75) and slightly expansive base. Largest known specimen (" Albatross " stn 5135) 8.7 x 9.6 mm in cahcular
diameter and 17.4 mm in height. A thick transversely corrugated epitheca extends to within 2-5 mm of calicular
edge. Costae equal in width (0.5-0.6 mm), flat, and highly porous, each costa uniformly covered with small
spines. Intercostal striae thin (0.05-0.10 mm), straight, and shallow.
Septa hexamerally arranged in 4 complete cycles, all 48 septa equally nonexsert, having smooth inner edges.
Si -2 equal in width, extending to columella. S3 about 1/2 width of S 1 -2- S4 that are adjacent to Si fuse to that Si
at calicular edge, their inner edges extending to the columella. Conversely, S4 that are adjacent to S2 also fuse to
that S2, each S4 bending toward the other S4 within its half-system, but not fusing with it and not quite reaching
the columella. Fossa shallow. Columella a discrete, elongate structure composed of short lamellae swirled in a
clockwise direction.
Remarks. — Balanophyllia gemma resembles a small, firmly attached specimen of B. cornu Moseley, 1881,
but can be distinguished by its well-developed epitheca, shallow fossa, and nonexsert septa.

Type Locality. — "Challenger" stn 201: 7°03'N, 121°48'E (Sulu Sea, off Zamboanga Peninsula), 187 m.
DESCRIPTION. — Corallum elongate-conical and straight, having a slightly compressed calice (GCD:LCD =
1.14-1.23) and attached by a robust pedicel (PD:GCD = 0.32-0.49). Largest known specimen (Karubar stn 49)
10.9 x 13.4 mm in calicular diameter and 18.4 mm in height, with a pedicel diameter of 4.4 mm. Costae quite
porous and well defined by narrow intercostal striae; however, lower 1/4 to 1/3 of corallum covered by a thin
epitheca.
Septa hexamerally arranged in 4 complete cycles in a strongly developed Pourtales plan. Si highly exsert (up to
3.0 mm), remarkably thick (up to 1.6 mm at calicular edge), having smooth, vertical inner edges that attain the
columella. S2 less exsert (up to 2.0 mm), only about 1/2 thickness of Si, and about 3/4 width of Si. Inner edges
of S2 also entire but do not quite attain the columella. S3 rudimentary, only about 0.7 mm exsert, 0.4 mm in
thickness, and about 1/4 width of an S2. S4 dimorphic in size: those adjacent to Si highly exsert (up to 2.8 mm),
fused to adjacent Si in robust triangular lancets; S4 adjacent to S2 slightly less exsert (up to 1.2 mm), also fused
to adjacent S2 but in less prominent lancets. Pairs of S4 unite before their common S3 high in fossa and extend to
the columella, sometimes fusing with inner edges of other S4 within their system near the columella. Inner edges
of S4 laciniate, bearing tall, regularly spaced teeth up to 0.6 mm tall. Fossa deep; columella rudimentary.
Remarks. — Balanophyllia parvula is distinguished from other Indo-West Pacific congeners by its remarkably
thick and exsert Si, which contribute to form tall, triangular calicular lancets. It is also distinguished in having a
strongly developed Pourtales plan, laciniate S4, and a rudimentary columella.
Moseley (1881) reported 3 specimens (syntypes) from "Challenger " stn 201 in his original description of
Balanophyllia parvula , 2 juveniles and 1 adult, the adult of GCD 8.0 mm being the figured specimen Both
juveniles were present at the BMNH in 1994, but the adult specimen could not be found. Judging from Moseley's
figure, B. parvula is a distinctive species represented by additional specimens reported above, but the 2 smaller
juvenile (GCD 4.4 and 4.8 mm) syntypes appear to be a different species, perhaps founder corallites of
a Rhizopsammia. Because of the possibility of 2 species being represented in Moseley’s type-series, the large
figured specimen is designated as the lectotype, even though it could not be found in 1994. ALCOCK (1902c)
reported 1 specimen of B. parvula from " Siboga " stn 251. A specimen at the NNM from this station fits
Moseley s figured B. parvula , but another Balanophyllia (species indet.) is also known from that station (ZMA).

ETYMOLOGY. — The species name crassiseptum (Latin crassus , thick + septum, literally fence or bar), alludes
to the thick septa of this species. The name is treated as a noun in apposition.
DESCRIPTION. — Corallum elongate-conical, straight, and compressed (GCD:LCD = 1.15-1.45). Pedicel
robust : PD:GCD = 0.45-0.55. Largest known specimen (holotype) 10.2 x 14.8 mm in calicular diameter,
17.0 mm in height, and 8.2 mm in pedicel diameter. Costae flat and porous, of variable width, and separated by
thin intercostal striae that sharply mark the costal boundaries. A thin epitheca covers basal 20-50% of corallum,
which is usually highly encrusted. Corallum white to light purple, the latter colour caused by an endolithic
microorganism.
Septa hexamerally arranged in 4 complete cycles. Si remarkably thick, as much as 1.5 mm at calicular edge.
Si quite exsert (up to 2.3 mm), porous, having a smooth inner edge that attains the columella. S2 also quite thick
(up to 0.9 mm) but only 1/2 as much as the Si. S2 up to 1.3 mm exsert, also porous, their inner edges also
attaining the columella. S3-4 0.5-0.6 mm thick. S3 rudimentary. S4 adjacent to Si more exsert than S2, but
S4 adjacent to S2 are as exsert as S3. Inner edges of S4 finely dentate. Fossa shallow, containing a well-developed,
discrete papillose columella.
Remarks. — Balanophyllia crassiseptum is very similar to B. parvula Moseley, 1881, both species having
very thick Si -2 and sometimes are found at the same stations. B. crassiseptum differs in having a larger columella,
less dentate inner edges of S4, and S2 that extend completely to the columella, not only 1/2 that distance as in
B. parvula.
The corallum of the holotype is bored by an acrothoracidan cirripede (Fig. 25 c) (see Grygier & Newman,
1985).

Description. — Largest known corallum (Karubar stn 22) cylindrical, elongate and slightly bent: 8.3 x
9.5 mm in calicular diameter and 71 mm in length, having 3 episodes of rejuvenescence. Epitheca extends to
within 9-10 mm of calicular edge, but most of theca worn and covered with foraminifera and serpulid tubes. Theca
highly porous. C1-3 thin (about 0.3 mm) and slightly ridged, whereas C4 are much broader (about 0.7 mm) and
flat.

Septa hexamerally arranged in 4 complete cycles. Si highly exsert (2.1 mm), having smooth inner edges that
extend to columella. S2 much less exsert (0.7 mm), about 4/5 width of an Si, also having entire inner edges.
S3 little exsert (0.3 mm), only about 1/3 width of an S2, having entire inner edges. S4 adjacent to Si highly
exsert (about 1.3 mm), at the calicular edge strongly fused to adjacent Si in triangular lancets. S4 adjacent to S2
considerably less exsert (0.3 mm) than those adjacent to Si, the inner edges of each pair of S4 within a half-system
fusing before its common S3 near the columella. Inner edges of S4 regularly dentate. Fossa of moderate depth,
containing a discrete, elongate, spongy columella that is sometimes constricted by the lower, inner edges of the
4 lateral Si.
Remarks. — Balanophyllia rediviva is similar to B. laysanensis Vaughan, 1907, in calicular features, but can
be distinguished by its elongate, cylindrical corallum; slightly ridged C1-3; and dentate S4.
Only 3 of Moseley's 4 syntypes could be located at the BMNH in 1994: the specimen illustrated
as Moseley's (1881) pi. 15, figs lOa-b is the only well-preserved corallum and is here designated as the lectotype.

Diagnosis. — Corallum ceratoid, often bent (up to 90°), and quite large. Largest Indonesian specimen (van
der Horst, 1922) 30 x 24 mm in calicular diameter, but some New Zealand specimens (Cairns, 1995) are larger
still. Pedicel robust: PD:GCD = 0.30-0.57. Basal 1/2 to 2/3 of theca epithecate and usually covered with
encrusting organisms. Costae flat, quite porous, and equal in width. Septa hexamerally arranged in 5 cycles in a
Pourtales plan, the 5th cycle rarely complete. S 1 -2 are 2-4 mm exsert, along with adjacent higher cycle septa
forming 12 triangular calicular lancets. S3 about 3/4 width of S1-2, the septa of all 3 cycles being independent,
smooth-edged, and reaching the columella; S4-5 have laciniate inner edges. Fossa deep. Columella discrete,
composed of short, swirled lamellar elements.
Remarks. — This species is characterised by attaining a large size (up to 79 mm in height and 33 mm in
calicular diameter), having epitheca, and usually having a bent corallum. It is more fully described and illustrated
by Cairns (1994, 1995).

ETYMOLOGY. — The species name (Latin serratus, toothed like a saw) refers to the jagged calicular edge of
this species.
DESCRIPTION. — Corallum large, elongate-conical to trochoid, straight, and slightly flared distally. Largest
specimen (the holotype) 34.1 x 27.1 mm in calicular diameter and 45 mm in height, with a pedicel diameter of
17.3 mm. Pedicel robust: PD:GCD = 0.27-0.51; base encrusting. Calice elliptical: GCD:LCD = 1.17-1.37.
Costae 0.7-0. 9 mm wide, flat, and covered with small spines arranged 3 or 4 across the width of each costa.
Intercostal striae thin (0.2 mm) and deep, contributing to a highly porous theca. No epitheca, but lower pedicel of
large specimens covered with a solid stereome, obscuring the porous nature of the theca. No encrusting organisms
noted on stereome. , _ . . , . .
Septa hexamerally arranged in 5 cycles, a specimen of 27 mm GCD having a complete 5th cycle, but the
largest specimen of 34 mm GCD with only 88 septa (4 pairs of S5 not formed). Si -2 highly exsert:
Si 4.0-5. 5 mm exsert, S2 3-4 mm exsert. Both Si and S2 are independent septa, quite thick at the calicular edge
(up to 1.9 mm), having smooth inner edges that extend inward to the columella. S3 much less exsert, about
3/4 width of the S1-2, not reaching the columella. S4 approximately 1/2 width of an S3. S5 adjacent to lower order
septa highly exsert, fusing at the calicular margin to their adjacent lower order septa, and forming calicular lancets.
Lower inner edges of the 2 S5 within each half-system that are adjacent to Si -2 meet and fuse near columella.
Conversely, the 2 S5 within each half-system that are adjacent to S3 are the smallest septa (less wide than an S4)
and little exsert, their inner edges bending toward and often fusing to adjacent S4. S5 usually porous near the theca,
having coarsely dentate inner edges. Fossa of moderate depth. Columella rudimentary, elongate, and constricted by
lower, inner edges of lateral Si. Columella discrete, composed of short lamellae.
REMARKS. — This species has a large corallum and septal arrangement similar to that of B. gigas Moseley,
1881. It differs in having no epitheca, a slightly flared calice with more highly exsert Si -2, and a straight corallum.

Type Locality. — Karubar stn 82: 9°30'00"S, 13r02'41"E (Arafura Sea south of Tanimbar Islands),
215-218 m.
Etymology. — The species name ( generatrix , Latin for "the one that produces offspring ) was the
unpublished museum (ZMA) name used by van DER HORST, who believed the species to be truly colonial. In fact,
the quasicolony results from contiguous independent planular settlement.
Description. — Corallum elongate-conical, usually occurring in a quasicolonial structure, i.e., individual
planulae settle close to one another, usually on the theca of an older or dead conspecific corallum, not as the result
of budding. The central individual may release the planulae that eventually colonize its theca, but in no case does
a corallum appear to bud from the theca of another living corallum. The bases of closely adjacent coralla often

coalesce (fuse) appearing as though they have a common basal coenosteum, but this is not due to coloniality. The
holotype is such a quasicolony consisting of a dead central corallum 20.1 x 33.7 mm in calicular diameter and
56 mm in height, on which 28 individual coralla have settled, one as tall as 45 mm. Coralla may attain a height
of 70 mm (" Siboga " specimens) but never bud additional coralla. The calice is circular to elliptical in cross section
(GCD:LCD = 1.1-1.95), the more elliptical calices characteristic of larger coralla. Pedicel robust, the PD:GCD
being about 0.33. Costae poorly defined, most of the porous theca covered with a fine spination; no epitheca.
Septa hexamerally arranged in 5 full cycles, passing through the 4 cycle stage at a GCD of 6-9 mm. Si -2 equal
in size, only very slightly exsert (about 1 mm), having finely dentate lower, inner edges. S3 similar to S 1-2, also
being independent, but their inner edges do not reach quite as far into the fossa as the Si -2. S4 rudimentary. Pairs
of S5 fuse fairly high in the fossa, having coarsely dentate inner edges that extend as far toward the columella as do
those of the Si -2. Fossa quite deep, containing an elongate, discrete columella composed of many very small
papillae.
Remarks. — Balanophyllia generatrix is similar to B. gigas Moseley, 1881, both having large coralla and
5 cycles of septa, but B. generatrix is distinguished by its quasicolonial habit, very deep fossa, finer columella,
and coarse dentition of the S5.
One quasicolony from "Siboga" stn 41 and 2 from Deki stn 58 were found with van der Horst labels reading
Dendrophyllia generatrix , the specimen from the "Siboga" station labelled as the "type", the others as a "cotype".
Independently, specimens from the "Albatross" and Karubar expeditions had been segregated by the first author as
an unidentified species. Van der Horst's unpublished manuscript name is adopted for it herein. It is
understandable that van der Horst considered this species to be a colony resulting from budding and thus called it
a Dendrophyllia, but for reasons explained in the species description it is here described as a Balanophyllia.

defined by narrow, porous intercostal striae; C5 usually slightly wider than C1-4. Costae slightly convex and
covered with small spines. Usually no epitheca.
Septa hexamerally arranged in 5 cycles, but 5th cycle occasionally incomplete by a few to several pairs of S5,
even in large coralla. S1-2 independent, having smooth inner edges. Si about 2.1 mm exsert, S2 about 1.5 mm
exsert, neither forming calicular lancets. Septa arranged in a Pourtales plan, the inner edges of S3 smooth, those of

the S4-5 laciniate. Fossa deep, containing a discrete, elongate, robust (up to 2.8 mm in width) columella
consisting of tightly fused lamellar elements swirled in a clockwise direction.
REMARKS — The large size (GCD > 30 mm) and septal number of B. imperials invites comparison with
2 other species that have large coralla: B. gigas Moseley, 1881 and B. serrata sp. nov. B. imperials differs in
having a much narrower pedicel and in lacking calicular lancets. It is also characterised by having a very deep fossa
and a robust columella.

Type Locality. — Unknown.
Diagnosis. — Attached young stage rarely observed (holotype of E. weberi). Species best known trom the
unattached flabellate corallum, which results from budding. Corallum triangular in face view, the edge angle
(exclusive of lateral crests) 50°-80° and the face angle changing from a narrow 15°-28° basally to a more open
42°-57° distally. Largest known specimen 38.9 mm in GCD and 34 mm in height (Cairns & Keller, ),
largest Philippine corallum (MUSORSTOM 2 stn 29) 12.3 x 16.9 mm in calicular diameter and 15.2 mm in height
Edge crests delicate, about 0.5 mm in thickness and up to 4 mm in height, occasionally bearing 1 or more small
buds Costae and intercostal spaces not well defined; costae unridged. Septa hexamerally arranged in 5 cycles in
a Pourtales plan. Si-2 up to 2.5 mm exsert. Pairs of S5 within each quarter-system fuse before their common S4,
bearing a paliform lobe at this junction. Fossa deep; columella elongate, nondiscrete, and spongy.
Remarks. — The face angle of E. grayi is low initially and broadens with height, whereas that of E. bulbosa
is high as a juvenile and decreases with height. Other difference between the only two Recent species in this genus
are given in the Remarks of E. bulbosa. A more complete description and illustrations of E. grayi are found in
Cairns (1991, 1994, 1995).

Type Locality. — Karubar stn 62: 9°02'10"S, 132°43'05"E (Arafura Sea southeast of Tanimbar Islands),
239-250 m.
Etymology. — The species name (Latin bulbosa, bulbous or swollen) refers to the thick basal pads on the
corallum base.
Description. — Corallum unattached, flabellate (GCD:LCD = 1.32-1.41), and massive, the largest specimen
(the holotype) 33.7 x 45.7 mm in calicular diameter and 38.5 mm in height. Shape of corallum varies
characteristically with age, the theca of lower 1/3 to 1/2 of a large corallum being exceptionally thick (up to
4 mm) and having an edge angle of 142°-155° and a face angle of 90°-104°. However, 10-14 mm above base the
theca thins to about 1 mm, the edge angle decreases to 50°-55°, and the face angle to 40°-45°. Edge costae crested as
high as 7 mm, being 1.5 mm thick on lower corallum. All 12 Ci-2 highly ridged (up to 1.7 mm) in upper
corallum, but flat and very broad in region of basal thickening, the Ci being as much as 8 mm wide, the C2 as
much as 1.5 mm wide. C3-4 of thickened region only 0.3-0.5 mm wide; C3-5 of upper theca poorly defined.
Asexual budding not observed in type series.
Septa hexamerally arranged in 5 cycles. S1-2 highly exsert (up to 5 mm), with thick (2 mm) upper edges and
straight inner edges that attain the columella. S3 not exsert, about 2/3 width of an Si -2, their inner edges extending
almost to columella. S4 rudimentary, each S4 flanked by a pair of S5 that fuse before the S4 and extend to the
columella as 1 septum where each fuses with the other S5 within its half-system. No paliform lobes. Fossa of
moderate depth. Columella an elongate, discrete structure composed of many short lamellae swirled in a clockwise
direction.
Remarks. — The massive basal thecal thickening of this species is solid, not the exterior of an overly
enlarged internal cavity, and thus has the effect of weighting the corallum as though with ballast, which might
facilitate an upright or near-upright posture for the corallum. This basal thickening is not a characteristic of all
larger coralla of Endopachys, since large coralla of E. grayi H. Milne Edwards & Haime, 1848, of GCD 40 mm
do not have it. E. bulbosa also differs from E. grayi in having: well-defined, ridged C1-2; much more exsert S1-2;
a larger discrete, convex columella; and in lacking paliform lobes. E. maclurii (Lea, 1833), known from the
Eocene of southeastern U.S., has 6 strongly produced Ci, but nothing resembling the basal thickening of
E. bulbosa.

DESCRIPTION (Philippine specimen). — Corallum elongate-conical, straight, and firmly attached by a broad
pedicel: 7.3 x 9.1 mm in calicular diameter, 13.0 mm in height, and 4.6 mm in pedicel diameter. Porous theca
covered with low, rounded, granular costae; no epitheca. Septa hexamerally arranged in 5 cycles, the 5th
incomplete (a total of 54 septa): Si-2>S3>S4>S5. Si-2 nonexsert, having straight, smooth, vertical inner edges
that attain the columella. S3 about 3/4 width of Si-2, having straight, finely dentate inner edges S4 about 1/3

DIAGNOSIS (specimen from "Albatross" stn 5130). - Corallum 10.3 x 8.6 mm in calicular diameter, 9.7 mm
in height and 4.2 mm in pedicel diameter. Costae not well-defined. Porous theca 0.7 mm thick; no epitheca. Septa
hexamerally arranged in 4 cycles according to formula: S,-2>S3»S4. Si-2 nonexsert, having straight, vertical,
smooth inner edges. S3 2/3 width of Si-2, having laciniate inner edges. S4 rudimentary, having laciniate inner
edges that do not fuse with adjacent septa. Fossa of moderate depth, containing a small elongate columella
composed of several twisted elements.
Remarks _ The "Albatross" specimen was compared directly to the holotype (ZMA Coel. 8642) and
considered to be conspecific despite several differences. The " Albatross " specimen is slightly smaller, has thinner
theca, and has fewer septa, the holotype having a septal complement of: 15:15:30 (60 septa), which is thought to
be an aberration of a hexameral plan. Most other characters are the same.
Leptopsammia crassa differs from L. poculum (Alcock, 1902) (Figs 28 a-b), in havmgmdistmct costae (the
C 1-2 of L. poculum are slightly raised) and in having a stouter corallum. L. stokesiana H. Milne Edwards &
Haime, 1848, appears to differ from L. crassa in having some S5 and a costate theca. However, so few specimens
of Leptopsammia are known from the Indo-Pacific that a clear distinction among species is wanting.

Description. — Corallum subcylindrical and relatively small, the largest known specimen (USNM 83006)
8.4 x 9.3 mm in calicular diameter and 7.7 mm in height. Calice only slightly elliptical (GCD:LCD =
1.05-1.15); pedicel robust (PD:GCD = 0.68-0.77). Lower 3/4 of corallum usually covered with a thin epitheca,
which is often encrusted by algae or foraminifera. Theca near calicular edge highly porous and usually not costate.
Septa hexamerally arranged in 4 cycles but pairs of S4 often missing in smaller specimens. Si about 0.8 mm
exsert, having a smooth upper edge, which is dentate adjacent to columella. S2 less exsert, 1/2 to 2/3 width of an
Si, having slightly coarser inner edge dentition. S3 almost as wide as S2, having coarse to laciniate inner edges,
each pair of S3 within a half-system bending toward its common S2 and forming a loose fusion with that septum
adjacent to columella. S4 rudimentary, usually represented by only a row of tall spines that project from inner
theca. Fossa shallow to moderate in depth. Columella a well-developed, elliptical, spongy mass; nondiscrete, often
with a slightly concave upper surface.
Remarks. — H. Milne Edwards & Haime (1848b) undoubtedly intended to name this species
philippinensis (for the Philippine Islands), not philippensis (for Philippe), but according to the ICZN (Article
32cii), the original spelling cannot be changed.

Type Locality. — "Siboga" stns 220 and 282: Indonesia, 54-278 m.
DIAGNOSIS. — Colony reptoid, most corallites well separated from one another but interconnected by costate
stolons semi-circular in cross section, up to 6 mm in width, 1-3 stolons issuing from base of each attached
corallite. Additional corallites also bud from theca of erect corallites. Corallites up to 45 mm in height and 9 mm
in GCD. Costae equal and well defined; intercostal spaces highly porous. Septa hexamerally arranged in 5 cycles,
the 5th cycle always incomplete. Si -2 independent; septa arranged in a well-developed Pourtales plan. Inner edges
of highest cycle septa laciniate. Fossa deep; columella discrete and spongy.
Remarks. — The distinctive basal stolons distinguish this genus from other dendrophylliid genera, and the
large size of the corallites distinguish R. verrilli from the other Indonesian species, R. minuta van der Horst, 1922
and R. nuda van der Horst, 1926. It differs from the central Pacific R. chamissoi Wells, 1954, in having larger
corallites with more septa. Previously reported specimens of R. verrilli had not been known to have corallites
budding from the theca of other corallites, which led CAIRNS (1991) to identify at least one colony as
Dendrophyllia gracilis , the latter species having budding from both corallite edges as well as a common basal
coenosteum. _ . , . , ... . ,
As VAN DER Horst (1922) cautioned, a corallite of R. verrilli broken from its base could easily be mistaken
for a species of Balanophyllia or a Cladopsammia. Thus, complete coralla are required for accurate identification.
A more complete description of this species is given by Cairns (1991).

Septa hexamerally arranged in 4 cycles in a Pourtales plan. Inner edges of Si -2 dentate. No paliform lobes;
columella spongy.
Remarks. — Rhizopsammia nuda is similar to R. minuta van der Horst, 1922 (Fig. 28 h), the only
apparent difference being that the corallites of R. nuda are about twice as tall as those of R. minuta. Althoug
VAN DER HORST described both species, he did not compare them. A syntype of R. nuda is deposited at the ZM
(Coel. 5525) and 3 more colonies labelled as syntypes are deposited at the BMNH (1939.7.20.852, 853, and 8. i )•

DIAGNOSIS. — Corallum consists of an elongate, cylindrical axial corallite from which secondary corallites bud
at right angle. Axial corallite unattached to substratum and often irregularly bent. Although some coralla achieve a
length of 53 mm (CAIRNS, 1994) and a GCD of 5.5 mm (ZIBROWIUS, 1980), the specimens reported above are
smaller, the longest only 15 mm and the calicular diameter ranging from 2-3 mm. Theca usually covered with a
thin epitheca giving lower corallum a porcellanous texture. Septa arranged in 3-4 cycles (depending on calicular
diameter) in a Pourtales plan. Si independent; each pair of S3 fuse before its common S2 high in the fossa.
Columella a small, nondiscrete, concave, spongy mass.
Remarks. — Eguchipsammia gaditana is described and figured in greater detail by ZIBROWIUS (1980) and

lower, inner edges that reach the columella. S2 not exsert, 3/4 width of an Si, also having smooth inner edges.
S3 small, each flanked by a pair of S4 that meet, fusing before inner edge of their common S3 and extend as
1 septum to the columella. Inner edges of all septa entire, not laciniate or dentate. Fossa of moderate depth,
containing a large discrete columella composed of tightly fused, swirled lamellae.
Remarks. — This species belongs to a group (see Cairns, 1994) of about 5 species within the genus
Dendrophyllia characterised by having arborescent colonies with most budding occurring perpendicularly from
a central axial corallite: D. ramea (Linnaeus, 1758); D. minuscula Bourne, 1905; D. indica Pillai, 1967; D. velata
Crossland, 1952; and D. ijimai Yabe & Eguchi, 1934. Its growth form, calicular diameter, and septal number is
similar to D. ijimai , but because its corallites are uniformly 1-2 mm smaller in diameter and because the type of
D. ijimai is not available for comparison, only a tentative identification is suggested.
Distribution. — Philippines : Verde Island Passage; Mindoro Strait; 97-130 m. Indonesia: Banda Sea (Kai
Islands); Flores Sea; 69-111 m. Elsewhere: Taupo Seamount, Tasman Sea; 135 m. D. ijimai is known from Japan
and the western Indian Ocean; 10-366 m (Cairns & Keller, 1993).

Diagnosis. Corallum dendroid, attached by a thick base, which firmly anchors the primary axial corallite.
A variable number of secondary corallites bud at right angle to the axial, and tertiary corallites may also be
present. The early colony stage, represented by the axial and several secondary corallites, was described as D. horsti
by Gardiner & Waugh (1939), but the more fully developed colony containing secondary and tertiary branches
was first illustrated by van der Horst (1922: pi. 8, fig. 6) as the typical form. When secondary and tertiary
corallites are elongate (up to 5 cm) a more open corallum results, described as D. subcornigera cylindrica

by EGUCHI (1968). The largest Philippine specimen (" Albatross " stn 5279) is a highly branched corallum
(as illustrated by van der HORST, 1922) 7 cm wide, 5.5 cm in height, and 13.4 mm in pedicel diameter,
consisting of 20 corallites. Corallites elliptical in cross section: up to 12.2 mm in GCD. Costae broad
(0. 6-0.7 mm), flat, and quite porous, separated by narrow (0. 1 mm), shallow intercostal striae. Edge zone extends
only about 1 cm below calicular edge, below which the theca is usually encrusted. Septa hexamerally arranged in
4 cycles in a Pourtales plan, the septa of the first 2 cycles independent and exsert. Fossa shallow, containing
a well-developed, well-delimited, compact columella consisting of many small lamellae that are tightly fused
together in a clockwise swirl. Columella massive, up to 3 mm in width, and often constricted into a central and
2 narrower lateral parts by the 4 lateral S i .
REMARKS. — Van DER HORST's (1922, pi. 8, fig. 6) illustrated specimen from "Siboga" stn 277 (ZMA Coel.
5477) is a colony 80 mm in height bearing corallites 5-6 mm in GCD. One of the other 2 syntypes from "Siboga"
stn 260 (ZMA Coel. 1254) is Eguchipsammia fistula. We therefore designate the specimen from "Siboga" stn 277
as the lectotype, the 2 from "Siboga" stn 260 as paralectotypes.
In their description of D. horsti, Gardiner & Waugh (1939) noted its resemblance to D. arbuscula , assuming
that their colonies were "genetic dwarfs" in comparison. The growth series represented in "Albatross" stn 5279
suggests that it is more likely that D. horsti simply represents the early growth stage of a larger colony.
Dendrophyllia arbuscula belongs to Cairns' (1994) "second group" of Dendrophyllia species, i.e., species
having relatively small, bushy colonies with irregular branching from an axial corallite. The horsti-slage of
this species is more fully described by CAIRNS (1994).

usually aligned on branch axis. Septa hexamerally arranged in 3 complete cycles: Si>S2^S3- Each pair of S3
meets before its common S2 to form a large palus (P2). Columella spongy.
Remarks. — According to the partial revision of the genus (Cairns, 1994), D. alcocki is one of at least
8 species in the "third group", characterised by having large, sympodially branched coralla. D. alcocki is more
fully described and figured by Cairns (1995).

Type Locality. — "Siboga" stn 95 (5°43.5'N, 1 19°40'E (Sulu Archipelago, Philippines), 522 m.
Description. — Extratentacular budding (and branching) occurs in an irregular manner leading to a massive,
irregularly shaped colony with occasional branch anastomosis. Budding often sympodial on distal, small-diameter
branches, but buds may occur on all branch faces, producing a 3-dimensional corallum. Largest known colony
(Karubar stn 25) 160 mm in height and 290 mm in width, consisting of 7 main vertical branches originating
from a common base 27 mm in diameter. Corallites slightly elliptical (GCD:LCD = 1.02-1.24), up to 4.7 mm in
GCD, standing up to 3 mm above branch coenosteum. Costae convex and well developed over entire branch
coenosteum. On small-diameter branches, costae about 0.3 mm wide, bearing only 1 costal spine across their
width, and are flanked by deep, highly porous intercostal striae about 0.2 mm wide. On large-diameter branches,
costae are broader (up to 0.6 mm), bear 2 or 3 small spines across their width, and are flanked by narrower (about
0.1 mm), less porous intercostal striae. Intercostal pores of large-diameter branches gradually filled in with
stereome, resulting in a very dense corallum.
Septa hexamerally arranged in 3 cycles in an indistinct Pourtales plan. All septa nonexsert. Si independent and
quite narrow (about 0.5 mm), having smooth inner edges that reach the columella. S2 equal to Si in size and
shape. S3 narrower than S1-2, having dentate inner edges, each pair of S3 within a system bending toward its
common S2 and fusing with that septum near the columella. Fossa deep and spacious. Columella a circular,
concave, nondiscrete, spongy mass.
Remarks. — Enallopsammia pusilla was described on the basis of what now appear to be 2 relatively short
distal branches of a larger corallum - a total of 25 corallites (see ZIBROWIUS, 1973). Additional larger specimens
are now available from near to the type locality ("Hakuho Maru" KH72-1-20) as well as near the type locality of
E. marenzelleri (Karubar stn 25). These colonies strongly suggest that the holotype of E. marenzelleri is simply
a larger, more robust colony of E. pusilla.
Distribution. — Philippines: Sulu Sea (Sulu Archipelago); 514-522 m. Indonesia: Banda Sea (Kai and
Selayar Islands); 325-730 m. Elsewhere: Macquarie Ridge; Nicobar Islands, Bay of Bengal; South China Sea (north

REMARKS. — Enallopsammia rostrata differs from E. pusilla in having unifacial corallites (i.e., calices
confined to one face of the corallum, anterior by convention), arranged uniserially on small-diameter branches. The
corallites of most specimens of E. rostrata also bear a prominent septocostal rostrum; however, some specimens
lack this structure, these referred to as the "amphelioides" form by CAIRNS (1982). Of the 3 lots reported above,
specimens from "Albatross" stns 5428 and 5429 have septocostal rostra, whereas those from Karubar stn 13 do
not. The rostrate specimens have small corallites (3 mm GCD), consistent with the "delicate" specimens reported
by Cairns (1995) from New Zealand, whereas the nonrostrate specimens have massive coralla.

S. D. CAIRNS & H. ZIBROWIUS
Description. — Corallum dendroid, but more or less uniplanar, achieved by profuse extratentacular budding
from a relatively small number (2-8) of massive axial corallites. Coralla may attain a large size: e.g., 1 m in
height and 5 cm in basal diameter. Corallites of small-diameter distal branches generally occur only on branch
edges, but on larger-diameter branches corallites more uniformly distributed on all branch faces. Corallites usually
project upward at a 45° angle from axial branch and stand 5-7 mm above branch coenosteum. Corallites usually
6- 8 mm in GCD, but Nemenzo (1960) reported giant calices 10-12 mm in GCD. Costae well defined,
0. 4-0.5 mm in width, convex to ridged, bearing 1-3 low granules across their width at any point. Intercostal
furrows long and continuous, 0.15-0.20 mm wide, and occasionally punctuated with circular pores about 0.3 mm
in diameter that penetrate deeper into branch core. Branch porosity greatest in distal parts, the pores becoming
infilled and thus more dense with age (SCHUHMACHER, 1984). Corallum white; live tissues a striking dark green
or brown-black.
Septa hexamerally arranged in 3 cycles: Si>S2»S3. Si nonexsert, having straight inner edges that attain the
columella. S2 3/4 width of an Si, also having straight inner edges that attain the columella. S3 usually
rudimentary, represented by a very narrow dentate to laciniate lamella. Fossa deep, especially in axial corallites.
Columella rudimentary, composed of a solid, elongate fusion of lower, inner edges of the S1-2.
Remarks. — Tubastraea micranthus is the only species in the genus to have a tree-like, dendroid growth form.
Being a common, shallow-water species, it has received various names, including several alluding to its tissue
colour.
As defined by SCHUHMACHER & ZIBROWIUS (1985), T. micranthus belongs to a unique ecological category
among the Scleractima, i.e., azooxanthellate, yet constructional and hermatypic. In other words, although it lacks
zooxanthellae, it produces large colonies that contribute to a reef structure. According to SCHUHMACHER (1984),
T. micranthus does not grow as fast as other branching zooxanthellate corals, but because it reinforces its branch
strength through secondary calcification, it remains competitive with other reef corals.
Distribution. — Philippines : Negros and Bohol; Sulu Sea (Zamboanga Peninsula and Sulu Archipelago);
7- 46 m. Indonesia: Molucca Sea (Halmahera); Banda Sea (Ambon, Banda, Kai, and Damar Islands); 0.5-60 m.
Elsewhere: widespread in tropical Indo-West Pacific from southwestern Indian Ocean to Fiji (most corals referred to
this species from Japan are Dendrophyllia)\ 0-50 m.

Type Locality. — Bora Bora, Society Islands (depth not given).
Diagnosis. — Corallum plocoid, forming spherical to mound-shaped colonies up to 10 cm in diameter. Most
corallites originate from a common basal coenosteum, only rarely budding from the wall of another corallite.
Corallites short and squat: 10-13 mm in GCD and rarely over 10 mm in height. Costae similar to those of
T. diaphana. Tissue usually bright orange, but may also be yellow, pink, or purple. Septa hexamerally arranged in
4 cycles, the 4th usually incomplete: Si>S2»S3>S4- Septal arrangement also similar to that of T. diaphana.
Fossa of moderate depth, containing a rudimentary crispate columella. Endothecal dissepiments occasionally
present.
Remarks. — WELLS (1983) listed 18-19 junior synonymys of T. coccinea and recognised a total of 6 valid
species in the genus. The synonymy given above is therefore incomplete but gives most of the Indonesian records.
A more complete description of this species can be found in Cairns (1994).
Four species of Tubastraea occur in the Indonesian region, 3 of which have similar corallite characteristics but
are distinguished by their colony size and shape: T. micranthus, large and arborescent; T. diaphana, small and
phaceloid; and T. coccinea, medium-sized and plocoid. The 4th species, T. faulkneri Wells, 1982, is similar to
T. coccinea in growth form but has very widely-spaced corallites that are sunken in thick coenosteum, and S4 that
pair before their common S3. Wells (1982) reported T. faulkneri from Pelau, the Banda Sea (Banda and Ambon
Islands), Mindoro, and the Galapagos Islands at 3-8 m. According to Wells (1983), only 2 other species of
Tubastraea are valid: T. tagusensis Wells, 1982, and T.floreana Wells, 1982, both from the Galapagos Islands and
distinguished by their septal characteristics (Cairns, 1991 : table 4).
Distribution. — Philippines: Mindoro and Zamboanga Peninsula, Mindanao; 3-6 m. Indonesia: Banda Sea
(Kai and Ambon Islands); 40 m. Elsewhere: cosmopolitan in tropical shallow water, including warm temperate
region of Japan; 1 .5- 1 10 m.

Material EXAMINED. — Philippines. " Albatross stn 5179, 5 colony fragments, including SEM stub 813
(USNM 97651).
Indonesia. Deki: unnumbered station near Banda, 3 June 1922, 30 m, 1 colony (ZMUC).
DESCRIPTION. — Small colonies formed by sparse intratentacular budding. Corallites sometimes budded in
series, resulting in a unifacial arrangement or budded sympodially, resulting in a loose, bushy corallum with
anastomosing branches. Calice circular: 2. 1-3.3 mm in diameter. Corallum completely epithecate, only 60 pm
thick at calicular edge. Epitheca composed of narrow (20-45 pm wide) horizontal bands that encircle the corallites.
Septal symmetry and size classes not clearly defined: 20-24 septa per calice. Septa highly porous, the larger septa
composed of 4 or 5 trabecular spines, having clavate, tuberculate tips about 0.12 mm in diameter. Most septa are
connected to their adjacent septa by narrow synapticulae. Columella composed of 3 or 4 granular rods, each up to
0.17 mm in diameter.
Remarks. We can find no scleractinian family in which to convincingly place the species described above
Its epitheca and size are similar to those of Culicia (Rhizangiidae), but it differs in budding mode and septal
construction. Its septal structure is similar to that of the Micrabaciidae, but it differs in having a solid epitheca and
being colonial. Until more specimens are examined, we reserve judgment on the family affinities of this unusual
coral.
Distribution. — Philippines: Sibuyan Sea; 68 m. Indonesia-. Banda Sea (off Banda Island); 30 m.
ACKNOWLEDGEMENTS

ABSTRACT
Thirty species of Pectinoidea are reported from off the Kai and Tanimbar Islands, Arafura Sea, at shelf to bathyal
depths (111-1244 m). Of these, eight are new records for the Indonesian Archipelago and two are new species:
Parvamussium conspecium sp. nov. (Propeamussiidae) and Veprichlamys versipellis sp. nov, (Pectinidae). On average,
the bathymetric occurence of species is shallower in the study area than in the South-West Pacific. Amussium
margaritiferum Dautzenberg & Bavay, 1912, is synonymized with Propeamussium investigatoris (E.A. Smith, 1906), and
Parvamussium crypticum Hayami & Kase, 1993, is synonymized with P. carbaseum Dijkstra, 1991. Lectotypes are
designated for five nominal taxa.

INTRODUCTION
The fauna of the eastern seas of the Indonesian archipelago has remained little known to this date. The Siboga
Expedition carried out nineteen stations (sins 250-268) near the Kai [= Kei] Islands in December 1899 (Tydeman,
1902: 14). At this occasion, seven species of Pectinoidea were collected in nearshore waters (Dautzenberg &
Bavay, 1912). Later, in 1922, during the Danish Expedition to the Kai Islands (Mortensen, 1923),
Dr Th. Mortensen made 63 dredge and trawl hauls in sublittoral to bathyal depths. The Pectinoidea were never
reported on, and this material (now in ZMUC) will be studied and treated elsewhere by the senior author. Finally,
the Indonesian-Dutch SNELLIUS-II Expedition (1984-1985) did some sampling in the northwest of Banda Sea, but
the investigations did not touch the Kai or Tanimbar Islands. The Pectinoidea of that expedition were described by
DIJKSTRA (1991).
The present paper reports on the Propeamussiidae and Pectinidae collected during the Indonesian-French
Karubar cruise. For a narrative of the cruise and complete station list, see CROSNIER, RICHER DE FORGES &
Bouchet (1997: this volume page 9). In addition, a few odd samples collected in 1980 during the Corindon
cruise in the strait ot Makassar have also been considered. We follow the style and presentation of an earlier paper
on deep-water Pectinoidea from the New Caledonia region (Dijkstra, 1995b), and extensive reference is made to
that paper: lists of synonyms and references, diagnosis and descriptions are not repeated for species already
discussed in the context of the New Caledonia fauna. The material is deposited in MNHN, Paris and POLIPI,
Jakarta, with voucher specimens in the private collection of the senior author. Comparative material from
Indonesia and type material was studied from various museum collections, namely AMS, BMNH MNHN
RMNH, WAM, ZMA, ZMUC, ZSI.

Type Material. — Lectotype (H 14, L 14, D 6.5 mm) ZMA Moll. 3.12.01 1, here designated, live taken.
Two paralectotypes: ZMA Moll. 3.12.012. DlJKSTRA (1990: 10) noticed the existence of three complete
specimens in ZMA, instead of 4 valves mentioned by DAUTZENBERG & Bavay (1912: 32). Bavay's manuscript
in KBIN mentions these specimens.
Type Locality. — "Siboga", stn 312, 08°19'S, 1 17°41’E, Saleh Bay, North coast of Sumbawa, Indonesia,
274 m.
Distribution. — Indonesia, shells in 200-288 m, live record in 274 m.
DESCRIPTION. — Shell small, up to ca. 14 mm high, fragile, transparent, slightly orbicular, equivalve,
inequilateral, slightly convex, auricles unequal, umbonal angle ca. 105°. Prodissoconch ca. 200 pm in height.
Both valves smooth, fine concentric striae on right valve. Auricles unequal with some more striae. Marginal apron
very fragile and mostly broken off. Internal ribs 6 and 2 small auricular ribs. Hinge line straight. Resilifer
triangular. No byssal fasciole, no byssal notch. Ctenolium absent. Colour pale brown with numerous small
reddish maculations on left valve, right valve paler without maculations, visible internal ribs whitish.
Remarks. — The present specimen from the Kai Island is somewhat similar to the type material of P. ina,
although more elongate (umbonal angle ca. 90°) and whitish transparent. P. steindachneri (Sturany, 1901), from
the northeastern Indian Ocean and the Red Sea, differs somewhat by having a more elongate shape and its colour
with larger reddish maculations and small whitish streaks. P. rubrotinctum (Oyama, 1951) from southern Japan to
New Caledonia differs from P . ina by having more numerous internal ribs (commonly 10) and the maculations are
somewhat larger.

TYPE Material. — Amussium investigatoris : lectotype (H 25.0, L 23.0, D 4.5 mm) ZSI M835/1, here
designated, live taken. Three paralectotypes: ZSI M836-838/1 and two paralectotypes: BMNH 1906.10.12.99-100.
Although the largest syntype (H 26.0, L 25.1, D 5.4 mm) is preserved at the BMNH, and closest to Smith' s
measurements, a syntype from the ZSI is selected as lectotype in accordance with Smith (1894: 158). The type
specimens are extremely fragile and the marginal apron often broken off. — A. margaritiferum : holotype ZMA

Moluccas, 472 m.
Distribution. — Northern Indian Ocean and eastern Indonesia. Present material alive in 176-466 m.
Description. — Shell relative small, fragile and semi-transparent, up to ca. 25 mm high, suborbicular,
equilateral, inequivalve, slightly convex, left valve somewhat more so than right, auricles equal, umbonal angle ca.
100-1 10°. Proclissoconch ca. 220 |im. Left valve sculptured with many irregularly spaced radial riblets, which are
squamous near ventral margin. Latticed microsculpture only in early growth stage (ca. 10 mm in height). Anterior
and posterior auricle with ca. 7-10 fine squamous radial riblets, weaker on right valve. Right valve sculptured with
fine regularly spaced concentric lamellae. Internal riblets 10 with 2 auricular riblets, and a few (2-4) intercostal
rudimentary riblets near the periphery. Hinge line straight. Resilifer triangular. No byssal fasciole, or byssal notch,
no ctenolium. Colour of left valve orange-tinted, of right whitish.
Remarks. — The present specimens correspond very well with the type material of P. investigatoris, although
the latticed sculpture is somewhat less developed. P.jeffreysii (E.A. Smith, 1885), from the Philippines, differs
by having a liner and more irregularly spaced radial sculpture, developed into concentric lamellae near the periphery
of the left valve. P . maorium (Dell, 1956), from the SW Pacific, differs by having a smooth surface, lacking the
latticed microsculpture, in early growth stage, and a finer radial sculpture on the left valve.

on the left valve, more numerous (10-14) and not so broad internal ribs. P. alcocki (E.A. Smith, 1894) differs by
having a more oval shape, a more fragile shell, and 11-12 narrower internal ribs. P. andamanicum (E.A. Smith,
1894) differs in its more oval shape, and its 9-10 shorter and narrower internal ribs. P. sewelli (Knudsen, 1967),
from eastern Africa, differs by having a fine radiating and concentric sculpture on the left valve, and 1 1 narrower
internal ribs. All these species are whitish transparent.

Type Material. — Holotype (H 7.4, L 7.5, D 2.8 mm) possible in the Oyama collection at Toba
Aquarium, Japan [not seen).
Type Locality. — Off Manazuruzaki, Sagami Sea, Japan, 234-291 m.
DISTRIBUTION. — Western Pacific from Japan to Indonesia, 234-467 m; present specimens alive in 283-
285 m.
DESCRIPTION. — Shell small, up to ca. 12 mm high, fragile, orbicular, nearly equivalve, equilateral, slightly
convex, auricles equal, umbonal angle 1 10-1 15°. Prodissoconch ca. 200 pm in height. Left valve sculptured with
fine, irregularly spaced radial lirae from early growth stage until beyond central part of disc, with microscopic
regularly spaced concentric lamellae, smooth central part and periphery. Auricles frequently smooth, sometimes
with fine concentric lirae. Right valve sculptured with fine, regularly spaced concentric lirae, more prominent near
ventral margin. Inner surface with 9-10 ribs, sometimes with one rudimentary intercostal one. Hinge line straight.
No byssal fasciole, or byssal notch. Ctenolium absent. Colour whitish or pale-brown transparent.
Remarks. — The present specimens fit the original description, but they reach a larger size, have fewer (9)
internal ribs and lack the very fine concentric lamellae on the left valve. A somewhat similar species is
P. malpelonium (Dali, 1908), from tropical eastern Pacific off Colombia, which differs by a coarser and more
developed microsculpture on the left valve, and more numerous (11) internal ribs. P. malpelonium is only recorded
from abyssal depths, 2690-4505 m (Grau, 1959: 14).

DISTRIBUTION. — Okinawa, alive in 7-20 m; eastern Indonesia, shells in 155-495 m.
REMARKS. — The present specimens are similar to the type material of P. carbaseum, and differ by their larger
size, up to ca. 5 mm high, and by having a few more rudimentary intercostal riblets. HAYAMI & Kase (1993: 56)
stated that P. crypticum differs from by "the byssal notch decidedly deeper, and the ratio of length/height a little
larger...". However, similar features are observed in the present material and P. crypticum is here synonymized.
P. araneum Dijkstra, 1991, differs from P. carbaseum by having a larger size, a latticed sculpture, and by having
fewer (only a few rudimentary) internal ribs. P. texturatum (Dautzenberg & Bavay, 1912) differs in external
sculpture, which is more prominent with lamellose radial costae and more widely spaced fine commarginal
lamellae.

Distribution. — Eastern Indonesia; shells in 100-290 m, alive in 212-250 m.
Description. — Shell small, up to ca. 5 mm high, fragile, semi-transparent, valves equally convex, elongate,
inequivalve, slightly inequilateral, auricles unequal in size, umbonal angle ca. 90°. Prodissoconch ca. 190 pm in
height. Left valve sculptured with ca. 20 primary and secondary irregularly spaced radial riblets, ca. 10 closely set
commarginal lamellae in early growth stage (before pre-radial stage), widely spaced on central part of disc and more
closely so towards ventral margin. Intersections of radial riblets and commarginal lamellae strongly squamous.
Anterior auricle larger than posterior and provided with closely spaced, strongly irregularly developed concentric
lamellae, more prominent anteriorly. A row of small lamellae produced near disc Hank. Right valve sculptured
with ca. 20 widely spaced concentric lamellose lirae. Sculpture of auricles similar to that of left valve. A radial lira
on anterior auricle near byssal fasciole. Internal ribs 9, commencing 1 mm below resilifer and developed towards
0.5 mm above periphery, with a small auricular riblet on each side. Hinge line straight. Resilifer triangular.
Byssal fasciole and notch small. Ctenolium absent. Left valve creamy-orange, right valve transparent white. Inner
side of both valves glossy. Dimensions (holotype): H 5.1, L 4.7, D 1.1 mm.
Remarks.— Parvamussium sp. cf. texturatum of DlJKSTRA (1991: 17, figs 44-52) differs from the present
material only in the internal ribs being shorter and slightly more numerous (10 instead of 9). P. texturatum
(Dautzenberg & Bavay, 1912) differs by having a more orbicular shape, a weaker sculpture of commarginal
lamellae on the left valve, and in having more numerous internal ribs (15). P. vesiculatum Dijkstra, 1995, differs
by having a more nodose sculpture at intersections on the left valve, more numerous closely spaced concentric
lamellae on the right valve, and less developed internal riblets (only a few rudimentary near the anterior and
posterior margins). P. undisonum Dijkstra, 1995 differs in size (larger, up to ca. 14 mm), is more oblique, and
more weakly sculptured with more close-set commarginal lamellae on the left valve.

Type Locality. — "Masandam insulam" [= Andaman Islands, India], depth unknown.
Distribution. — Northeastern Indian Ocean and Indonesia.
Remarks. — The present specimens are similar to the type material. The internal ribbing and sculpture
are variable, from weak to more prominent, sometimes lacking sculpture or commarginal lamellae on the left
valve. P. thetidis somewhat differs by having a weaker sculpture and more close-set commarginal lamellae on
the left valve. P. siebenrocki (Sturany, 1901) from the northwestern Indian Ocean is nearly identical to
P. cristatellum , and differs only in the radial costae on the left valve being somewhat weaker; however,
intermediates seem to exist and the two may be synonyms. P. formosum (Melvill, 1907) from the western Indian
Ocean is quite smooth and the auricles are very finely sculptured and more similar to those in P. torresi
(E.A. Smith, 1885).

Distribution. — Southern Philippines, Indonesia, Coral Sea to the Loyalty Islands; 205-600 m, alive in
205-355 m.
Remarks. — The present specimens are similar to the type material; a few specimens (stn DW 01 and
DW 32) have colour maculations. P. formosum from the Arabian Sea is closely related but differs in having
a more prominent sculpture of radial striae on auricles and near the anterior and posterior margins of the left valve.
P. scitulum (E.A. Smith, 1885) differs from P. torresi by having a more compressed shell, more prominent
sculpture of radial striae, and by being more brightly coloured. The right valve of P. torresi is covered with
regularly spaced concentric lirae, which are generally lacking on P. scitulum.

secondary radial riblets commencing at central part of disc, and increasing towards ventral margin. Costae
squamose. Microsculpture of interspaces variable: early growth stage with diverging striae near anterior and
posterior margin, shagreen microsculture above central part of disc and near ventral margin, in between radial striae
and diverging to the anterior and posterior margins. Anterior auricle of left valve larger than posterior, sculptured
with 10 weakly developed squamous radial lirae; posterior auricle with 6 fine squamous radial lirae, interspaces of
early growth stage striae microscopically reticulated. Auricles of right valve sculptured with more prominent radial
costae, fewer in number (anterior 6, posterior 5). Anterior hinge line straight, posterior somewhat suppressed.
Byssal fasciole broad, byssal notch rather deep. Inactive and active ctenolium beside ledge of suture, with 4 teeth.
Postero-lateral margins of disc scarcely gaping. Resilifer elongate triangular. Inner surface of both valves plicate
near periphery. Colour creamy with pink-reddish dots and scales. Dimensions (holotype): H 23.4, L 20.0,
D 6. 1 mm.
REMARKS. — Juvenile specimens resemble V. jousseaumei (Bavay, 1904), from the western Pacific, which
differs by the absence of intercalating ribs and of the shagreen microsculpture. Adult specimens of V. versipellis
differ by having shagreen microsculpture on the anterior auricles, on the central part of the disc and near the ventral
margin, whereas V. jousseaumei has radial striae. V. versipellis has many (ca. 50), irregularly spaced, radial
riblets, V. jousseaumei fewer (ca. 20), regularly spaced, radial ribs. V. perillustris (Iredale, 1925) from southern
and southeastern Australia differs having by a more oblique shape, fewer (ca. 20) radial ribs, more prominent scales
on the ribs, and lack of a shagreen (reticulated) microsculpture. V. kiwaensis (Powell, 1933) resembles
V. perillustris and differs from V. versipellis by having fewer (ca. 20) regularly spaced radial ribs and more
prominent microscopic striae; shagreen microsculpture is absent. V. incantata (Hertlein, 1972) from the Galapagos
Islands differs by attaining a larger size (ca. 45 mm high), having a more elongate shape, a larger convexity of the
valves and lacking the shagreen microsculpture.
Etymology. — From the Latin versipellis , adj. = metamorphosis, with regard to the inconstancy of shell
microsculpture.

Genus HAUMEA Dali, Bartsch & Rehder, 1938
Haumea Dali, Bartsch & Rehder, 1938: 86. Type species (OD): Haumea juddi Dali, Bartsch & Rehder, 1938 (= Pecten
loxoides G.B. Sowerby II, 1882). Recent, Hawaiian Islands, 7-15 m.
Diagnosis. — Free swimming Aequipectinini, slightly obliquely suborbicular, right valve more convex than
left, auricles subequal, valves sculptured with 18-20 radial costae, interspaces with fine concentric lamellae,
auricles weakly sculptured with 4-6 radial riblets and fine close-set concentric lamellae, byssal notch moderately
deep, ctenolium present.
DISTRIBUTION. — Pliocene-Recent. Western Indian Ocean, western and southwestern Pacific; littoral to
sublittoral depths.
Remarks. — Hertlein (1969: N357) treated Haumea as a synonym of Argopecten Monterosato, 1899, a
subgenus of Chlamys. Waller (1991 : 32) placed Argopecten in the Aequipecten group, or Aequipectinini (1993 :
198). Haumea differs from Argopecten by having a more compressed, and somewhat obliquely orbicular left valve
(in Argopecten more convex and elongate, especially in young specimens) and smaller, subequal auricles (in
Argopecten larger, inequal with a prominent anterior auricle in the right valve). Microsculpture of Haumea is finer
with more closely spaced concentric lamellae. The genus includes H. inaequivalvis (G.B. Sowerby II, 1842),
H. loxoides and H. rehderi (Grau, 1960). Argopecten is not known in the Indo-Pacific region.

Indonesia. Karubar, Kai Islands: stn DW 30, 05°39'S, 132°56'E, 111-118 m, 1 rv.
Type Material. — Lectotype, here designated, the shell figured by Reeve (1852: pi. 1, fig. 6; H 30.8,
L 33.5, D 13.5 mm) BMNH 1994126/1. Two paralectotypes: BMNH 1994126/2-3.
Type Locality. — Philippine Islands.
DISTRIBUTION. — Western and northeastern Indian Ocean, western, southwestern and central South Pacific;
alive in 3-46 m (Dijkstra, unpubl. data).
Description. — Shell rather small, usually 20 mm high, occasionally up to ca. 30 mm, suborbicular,
inequivalve, right valve more convex than left, auricles unequal, umbonal angle ca. 100-1 10°. Prodissoconch
height ca. 220 ftm. Both valves sculptured with 18-20 regularly spaced, prominent radial costae. Radial ribs near
anterior and posterior margin weakly concentrically striated. Interspaces between radial costae with concentric
lamellae. Auricles sculptured with 2-4 weak radial riblets. Inner surface strongly plicated near ventral margin.
Hinge line straight. Byssal notch moderately deep. Resilifer obliquely triangular. Active ctenolium weak, with
4-5 teeth. Colour blackish grey or brownish marked with a few white spots and black streaks, right valve whitish
or light brown.
Remarks. — The present young specimen is similar to the type material. Young specimens could be easily
confused with the closely related species Haumea rehderi (Grau, 1960) from the same region, which differs by
having more prominent and widely spaced concentric lamellae between the radial costae, more prominent radial
riblets on the auricles, and a deeper byssal notch. Haumea loxoides differs by having a more fragile shell, a more
oblique shape, and a creamy mottled with red colour.

TYPE Locality. — P. singaporinus: Singapore. — P. pica: "New Zealand" [incorrect locality].
DISTRIBUTION. — Throughout the southwestern Pacific to northern Australia; alive from intertidal to subtidal
depths. Present specimens probably washed into deep water.
DESCRIPTION. — Shell up to ca. 45 mm high, suborbicular, equilateral, equivalve, very compressed, auricles
unequal, umbonal angle ca. 90°. Prodissoconch height ca. 260 |im. Both valves sculptured with 18 to 24
(commonly 20 to 22) regularly spaced, smooth rounded radial costae. Interspaces between radial costae with fine
concentric lamellae. Anterior auricle of left valve sculptured with 6-8 weak radial riblets and very fine close-set
concentric lamellae; riblets nearly absent on posterior auricle. Hinge line straight. Byssal notch moderately deep.
Ctenolium well-developed with 4-6 teeth. Resilifer triangular oblong. Inner side with prominent plicae near ventral
margin. Colour greyish or creamy with brown and/or whitish maculations and streaks.
REMARKS. — Present specimens are similar to the original and subsequent descriptions and illustrations by
Reeve (1853), although with fewer radial costae (18-20). Sowerby (1842) mentioned 24, Reeve (1853) ca. 22
and KUSTER & Kobelt (1888) 20-22 radial costae. Material examined from throughout the southwestern Pacific,
South China Sea, Malaysia and Indonesia (BMNH, HD, MNHN, RMNH, ZMA) shows variation in number of
radial costae, decreasing to eastern Indonesia and northeastern Australia. It is possible that V. cumingii (Reeve,
1853) from Queensland is only a geographical variant (under study).

Type Material. — Holotype BMNH 1950. 1 1 .14.8.
Type Locality. — "China Sea" [= South China Sea].
Distribution. — Western Indian Ocean, western and southwestern Pacific; alive in subtidal to sublittoral
waters (2-90 m) (DIJKSTRA, unpubl. data).
Description. — Present specimens of the Kai Islands are up to 25 mm high, somewhat triangularly
elongated, nearly equilateral and equivalve, right valve slightly more convex than left valve, auricles subequal,
umbonal angle 85°. Prodissoconch heigh ca. 250 pm. Both valves undulated and sculptured with 7 rounded radial
costae. Microsculpture consisting of very fine and closely set, commarginal lamellae. Faint secondary radial riblets
developed on radial costae near ventral margin. Auricles weakly sculptured with 4-5 radial riblets. Hinge line
straight, somewhat raised on right valve. Inner surface plicated, more prominently so near periphery. Resilifer
triangular, erected. Byssal notch very small, byssal fasciole absent. Ctenolium weakly developed with 3 teeth.
Colour creamy, maculated with dots and streaks, right valve more uniform and paler.
Remarks. — The present valves differ strongly from the type material of P. aurantiacus by having a more
orbicular shape (typical specimens are more elongated), fewer 7 vs 9-15) radial costae and are nearly lacking
secondary radial riblets on costae (strongly developed and scabrous in typical specimens). The shape is somewhat
similar to Mirapecten rastellum (Lamarck, 1819), but the latter is sculptured with strongly erected scales on the
radial costae and dorsal margin of right valve. The byssal notch is also wider than in M. rastellum and the auricles
are larger.
DISCUSSION
A total of 19 species ol Propeamussiidae and 11 species of Pectinidae are present in the material from the
Karubar cruise in the Arafura Sea. Twenty-eight species (18 propeamussiids and 10 pectinids) were collected near
the Kai Islands, and twelve species (6 each of propeamussiids and pectinids) near the Tanimbar Islands. Two
species ( Parvamussium conspectum and Veprichlamys versipellis) are new to science, and 8 are new records for
Indonesia: Propeamussium alcocki, P. investigators, P. rubrotinctum, Parvamussium squalidulum, P. thetidis,
P. vesiculatum, Delectopecten fluctuatus, and Haumea inaequivalvis.
There are 33 stations without pectinoids and 26 stations have only one species. Five stations (02, 13, 29, 31,
32) have six species and station 18 has seven species (3 of them live-taken). Half of the species are represented by
at least one live-taken sample, others only by empty shells. Haumea inaequivalvis and Volachlamys singaporina
are intertidal to subtidal species and the Karubar records represent empty shells carried downslope to water depths
where the species is apparently not normally living. Other than these two species, the depth range indicated by
empty shells appears compatible with what is known for the relevant species elsewhere in the Indo-Pacific.
The Kai Islands were selected as the site of the Danish 1922 and Karubar 1991 Expeditions because
Mortensen had hypothesized that deep-sea species occured there at considerably shallower depths than elsewhere
in the world. Ten species of Pectinoidea were collected alive during both the Karubar and New Caledonia
dredging programs (DIJKSTRA, 1995b) and in this respect it may be of interest to compare their bathymetric range
in the two regions (Table 1). Propeamussium alcocki appears to range deeper in the Arafura Sea than in New
Caledonia, but the first occurence of 8 species is shallower or considerably shallower in the Arafura Sea than in
New Caledonia. The limited evidence available thus appears to support MORTENSEN's hypothesis.

Table 1. — Bathymetric range of Pectinoidea in the Arafura Sea (thick bar) and New Caledonia (thin line).
The Indonesian archipelago has been touched by several major expeditions ( Challenger , Valdivia , Galathea ), and
was the main focus of several specific ones ( Siboga , Snellius-II. Karubar). A total of 43 deep-water pectinoids
are now recorded from the archipelago (Table 2, next page), with most of present knowledge based on the last three
mentioned expeditions. Despite this collecting effort, the deep-sea fauna of Indonesia is still probably very
incompletely known:
(a) Seventeen species (40%) were first discovered or recorded during the recent SNELLIUS-II (1984-85) and
Karubar (1991) expeditions.
(b) Nine species (21%) taken during the historical Challenger, Valdivia and Siboga expeditions have never been
taken again since then in Indonesian waters.
(c) In the Karubar material, on average, each species is present at 4.4 stations, but there is considerable
variation in occurence patterns, with Delectopecten alcocki present at 23 stations and 9 species present at single
stations. The new species and species representing new records for Indonesia are present on average at 3.9 stations:
it thus seems that they are not significantly rarer than the species already known from Indonesia, which are present
on average at 4.7 stations.
This indicates that rather many more species of Pectinoidea will probably be discovered when new regions of
the Indonesian archipelago will be properly sampled.

INTRODUCTION
Rather few species of Muricidae were collected during the French-Indonesian Karubar cruise on board of the
Indonesian R. V. "Baruna Jaya 1 Indonesia and Papua New Guinea have a very diverse muricid fauna (DHARMA,
1988; Hinton, 1972, 1979), and it was thus unexpected that as few as 16 species are represented in the expedition
material. Furthermore one third (6 species) occurred only as empty shells. Eleven species (69%) are represented by
a single sample and none has been collected at more than three stations. Most probably the bottom types surveyed
during KARUBAR were not favourable to muricids. Most hauls sampled fauna on bottoms of mud or sandy mud,
whereas a majority of muricids favour hard substrates. Only 15 stations (16% of all stations) yielded muricids, and
in 10 of these the family Muricidae is represented by a single species. Three stations (stn 15, 22, 50) yielded two
species, and two (stn 18, 30) gave three species each. Despite the small size of the collection, as many

recorded, fauna, at least in the 100-250 m depth range, where most of the findings have been made.

Remarks. — The identity of the single collected specimen is uncertain. It is probably not C. pliciferoides, but
this is the most similar species. The present material is lighter, and relatively smaller, with narrower varices.
Nevertheless, the shell of C. pliciferoides being very variable morphologically, an examination of more numerous
specimens from the same region is necessary before a decision can be reached.

DESCRIPTION. — Shell up to 11.2 mm (holotype), slender, spinose, lightly built. Spire high, with
1.5 protoconch whorls, and up to 5 weakly convex, spinose teleoconch whorls. Suture impressed. Protoconch
broad, globose, smooth, glossy. Terminal varix unknown (eroded). Axial sculpture of teleoconch whorls
consisting of numerous, weak growth striae and high, rounded varices, each with long, narrow, sharp primary and
secondary spines. Shoulder spine longest, weakly adapically bent. First and second whorls with 9 varices, third
with 9 or 10, fourth with 10 or 11, last whorl with 10 varices. Spiral sculpture of strong, smooth, primary and
secondary cords: first to third whorl with 2 primary cords, fourth with 2 primary and 1 secondary cords, shoulder
with 1 secondary cord, last whorl with 5 or 6 primary and secondary cords, shoulder with 1 secondary cord.
Occasionally with numerous, narrow spiral striae. Aperture small, rounded. Columellar lip flaring, smooth. Lip
erect, adherent adapically. Anal notch indistinct. Outer lip smooth, with 4-6 more or less visible denticles within,
very variable in strength. Siphonal canal long, narrow, straight, open, smooth. White.
Remarks. — The genus Leptotrophon Houart, 1995 was described to include numerous small species of
Trophoninae with a spinose, delicate, and small shell, all from the New Caledonia region (Houart, 1995b). The
occurrence of another, new species in Indonesia is a very interesting range extension for the genus. Leptotrophon
kastoroae is similar to three other spinose species of Leptotrophon-. L. spinacutus Houart, 1986; L. bernadettae
Houart, 1995, and L. rigidus Houart, 1995. From L. spinacutus, L. kastoroae differs in having relatively longer
spines, a narrower siphonal canal, and a broader aperture with a narrower apertural varix. From L. bernadettae, it
differs in its relatively broader and rounded protoconch, narrower columellar lip, and more slender shell.
L. kastoroae is relatively smaller than L. rigidus, with more numerous, longer spines, a twice larger protoconch,
and a narrower siphonal canal.

ABSTRACT
The deep-water Cancellariidae collected during the Karubar cruise near the Kai and Tanimbar Islands are represented
by 20 species (9 new), only two of which were recorded earlier from the Arafura Sea. As many as 14 species (70% of the
total) are represented by single specimens, and 17 (85%) have been collected at one station only: this points to a still
more diverse cancellariid fauna. New species of Axelella, Perplicaria, and Solatia represent the first occurence of these
genera in the Indo-West Pacific. Admete aethiopica Thiele, 1925, recently suspected to be a species of Turridae, is
confirmed as a cancellariid.

INTRODUCTION
The malacofauna of the Indonesian seas has not yet been adequately inventoried. A review of the Cancellariidae
from that area has been published (VERHECKEN, 1986), based on the rather poorly documented material collected
mainly early this century, furthermore mostly from shallow water. By contrast, the material studied here is

excellently documented and originates from depths from the continental shelf down to about 800 m. Despite that
only a limited geographical area of the northern Arafura Sea was covered, it is unexpectedly rich in specimens (72)
and species (20, nine of which are here described as new to science) of Cancellariidae.
Supraspecific taxonomy of Cancellariidae has not yet been worked out satisfactorily and generic allocation of
several species discussed here proved to be difficult. Genera of small deep-water cancellariids have been named based
on fossil and Recent Australian and New Zealand species. A great confusion prevails, which will be difficult to
unravel without reevaluation of the relevant type material and examination of representative collections. Hence,
generic names used here may be open to discussion and their usage does not necessarily imply their recognition as
the most appropriate name. Therefore, in this paper all genus-level names are treated as genera (no subgenera), and
no new generic names are introduced.

SYSTEMATIC ACCOUNT
Family CANCELLARIIDAE Forbes & Hanley, 1851
Subfamily CANCELLARIINAE
Genus AXELELLA Petit, 1988
Axelella Petit, 1988: 130 (nom. nov. for Olssonella Petit, 1970, non Glibert & Van de Poel, 1967). Type species (OD):
Cancellaria smithii Dali, 1888. Recent, Western Atlantic.
Species of Axelella are found almost exclusively in central American seas, both Caribbean and Panamic-
Paciftc. The two species treated here are certainly not typical representatives and are placed in the genus only by
lack of a more appropriate genus.

MATERIAL EXAMINED. — Indonesia. Karubar, Kai Islands: stn DW 31, 05°40'S, 132°51'E, 288-289 m, 1 dd.
Type Material. — Holotype MNHN.
Type Locality. — Indonesia. Off Kai Islands, Karubar, stn DW 31, 05°40'S, 132°51'E, 288-289 m.
DESCRIPTION. — Shell biconical, with convex whorls and a large aperture. Protoconch (Figs 2-3) smooth,
paucispiral with 1.0 whorl, maximum diameter 1.0 mm, exposed height 0.7 mm. Transition to teleoconch marked
only by start of teleoconch sculpture. Teleoconch with 4 1/4 convex whorls. Axial sculpture of narrow rounded
ribs: 12, 12, 13 and 12 on first to fourth whorl respectively, 10 on last whorl. Spiral sculpture of broad flat bands,
6 on first teleoconch whorl. From the second whorl on, between the broader bands up to 4 narrower ones occur, all
bands fitting closely together. On third and fourth whorl 8 primary bands, plus secondary and tertiary ones. On last
whorl up to 60 spirals bands, divided axially by sharp, raised incremental riblets (Fig. 4). Suture impressed, very
slightly canaliculate. Aperture semicircular, tapering anteriorly into a short siphonal canal oriented slightly
abaxially. Columella straight, parallel to shell axis, with three strongly oblique folds, adapical one strongest, weak
abapical fold near rim of siphonal canal. Outer lip with crenulated edge, 14 lirae inside. Umbilical slit narrow,
almost completely closed by columellar callus. Siphonal fasciole present but not strong.
Dimensions: 15.5 x 10.4 mm.
REMARKS. — Axelella kastoroae is rather similar to Cancellaria quasilla Petit, 1987 (= Cancellaria cretacea
E. A. Smith, 1899, non Nyst, 1881) from off Southern India, Burma, and off Northern Somalia. The apical
whorls of the holotype of C. quasilla (material examined in the Zoological Survey of India, Calcutta) are strongly
eroded, but specimens from off Somalia (AV) have a multispiral protoconch. In spite of a large distance in time
and space, A. kastoroae also resembles Cancellaria paraguanensis H. K. Hodson in HODSON & HODSON, 1931,
from the Miocene of Venezuela, as figured by JUNG (1965, pi. 75, figs 15-16). The latter species grows up to
36 mm, has a stronger siphonal fasciole and fewer axials on the last whorl as compared to A. kastoroae. HODSON
(1931: 44) and JUNG (1965: 555) did not place C. paraguanensis in a subgenus and Petit (1987: 154) compared
C. quasilla with species of Merica, stating that a determination of subgeneric placement was not yet possible.
These species, which in my opinion are congeneric, differ from typical Cancellaria (s. 5.) species in lacking the
bifid posterior columellar fold. Further, Axelella kastoroae differs from species of Merica in its much more convex
whorls and its broad axial sculpture. The microsculpture of A. kastoroae (Fig. 4) resembles that of Nipponaphera
habei Petit, 1972 (Japan and the Philippines) but is finer; the latter species has a multispiral protoconch and
the teleoconch whorls are strongly angulate. In general form, the new species also bears some resemblance to

Axelella funiculata (Hinds, 1843) from western Central America, but that species is more elongated, it has a much
more impressed suture and stronger columellar folds, it lacks the sculpture of sharp, raised incremental riblets and
it has a multispiral protoconch.

I dd.
Type Material. — Holotype (11x9 mm), DMNH 126397.
Type Locality. — Philippines. Off Balicasag, Bohol Island, 300 m.
DISTRIBUTION. — A. nodosivaricosa is known from the Philippines and Japan (AV, KBIN), now possibly
extended to the Arafura Sea.
REMARKS. — The rather eroded shell (14.9 x 9.8 mm) is very close to specimens of A. nodosivaricosa from
the Philippines and Japan (AV, KBIN) but differs from them in having the whorls more inflated, fewer axial ribs
on spire whorls (8, 9, 9 vs 14, 13, 9 on second to fourth whorl respectively), and spiral sculpture only weakly
indicated. The last adult whorl has 7 axial ribs in both the KARUBAR specimen and typical A. nodosivaricosa. The
present specimen has a paucispiral protoconch with 1 whorl, maximum diameter 0.9 mm, exposed height 0.7 mm,
nucleus diameter 0.4 mm. Typical -4. nodosivaricosa (KBIN. AV, Figs 60-62) have a protoconch with 1 1/4 to
1 3/4 whorl, maximum diameter 0.95 mm, exposed height 0.8 mm, nucleus diameter 0.3 mm, and this results in
rather different general appearance (Figs 6-7 vs Figs 61-62). The main difference resides in the regularly squared
cancellation of the earlier whorls in A. nodosivaricosa, versus the strong axial sculpture in the present specimen.
Since only one rather eroded shell is at hand, it is hard to judge the value of cited differences; therefore this shell is
here provisionally identified as conforming A. nodosivaricosa.

Distribution. — Philippines, now extended to the Arafura Sea, alive in 352-688 m, shells in 243-809 m.
Remarks. — The protoconch of most specimens is heavily corroded. Fresh shells have a pale fawn perios-
tracum with strong solid hairs, 0.5 mm long, flattened and broadened at base. This species is nearest to Bonellitia
garrardi , from which it differs by its larger size, sharper sculpture, and paucispiral protoconch (Figs 9-10).
B. garrardi has more rounded whorls, and lacks the deep suture and distinct shoulder of B. atopodonta.

Remarks. — The present specimen is small (7.4 x 4.6 mm), slightly worn, and has part of the outer lip
broken. Its large, blunt-tipped multispiral protoconch (1 7/8 whorls; maximum diameter 1.0 mm; exposed height
0.6 mm; Figs 12-13) differentiates it from the sympatric B. atopodonta and from B. superstes Finlay, 1930, from
New Zealand, both having a relatively high paucispiral protoconch.
Genus BROCCHINIA Jousseaume, 1887
Brocchinia Jousseaume, 1887: 221. Type species (SD by Sacco, 1894: 68): Valuta mitraeformis Brocchi, 1814 non
Lamarck, 1811 [= Brocchinia tauroparva Sacco, 1894], Pliocene, Italy.
Inglisella Finlay, 1924 [type species (OD): Ptychatractus pukeuriensis Suter, 1917, Miocene, New Zealand]
may be a synonym. Finlay (1924: 501) First placed P. pukeuriensis provisionally in Brocchina [sic], but later
proposed the new genus Inglisella, differing "in the thin shell, different form of growth, discrepant sculpture, much
straighter columella, and rather pronounced posterior notch in the outer lip just at the keel" (FINLAY, 1924: 513).
The Karubar species have a solid shell and a columella with rather strong folds; consequently they are here
placed in Brocchinia.

Total 16 specimens, dimensions up to 12.8 x 5.4 mm, with up to 6 teleoconch whorls.
Type Material. — C. fischeri: Not located. Three shells from the Cuming collection, BMNH 1968419,
were considered possible syntypes and figured as such by GARRARD (1975) and Habe (1985). However, the
locality "was written in pencil on the reverse of the board, together with the citation for the original description;
the front of the board also bears the locality Korea. The only original writing on the board is the label on the front
with the name ' Fischeri , A. Ad' and the initials M.C. on the reverse denoting the origin of the specimens with
Hugh Cuming" (K. Way, in lilt, viii-1995). This lot is now in the general collection, BMNH, with the label
"These specimens had been separated as the types; this is unlikely".
S. abyssicola: whereabouts of holotype (7.9 x 4.8 mm) and paratype (6.8 x 4.2 mm) not mentioned by Habe
(1961).
Type Locality. — C. fischeri: "Strait of Corea", 114 m. — 5. abyssicola: Japan, off Kochi Prefecture,
Shikoku, about 150 m.
Distribution. — Korea; formerly recorded from Japan [A. Adams, 1868: 368; and a single specimen each in
KB IN, ZMHU, NMW (1955.158.1906), and BMNH], but such records have not been confirmed recently (Habe,
1985: 10); China Sea, off Pratas Island, 234 m (USNM 284939); Philippines (USNM 288372, 289413; said to be
from 40 and 1017 m !); Borneo, 622 m (USNM 289966); off South and Western Australia, 79-147 m (GARRARD,
1975: 39).
Remarks. — Brocchinia fischeri has remained little known in the literature. It was omitted by LOEBBECKE
(1881-1886), and TRYON (1885: 84) simply mentioned it under the "unfigured and unidentified species of
Cancellaria". It has only been illustrated by Garrard (1975) and Habe (1985). B. fischeri proves to be rather
variable (Figs 14-18), spire angle 36°-41°. Most Karubar specimens as well as 8 specimens in AMS show a
pitted surface at magnification x 30-60, and SEM pictures show a complex surface with irregularly shaped cavities
(Fig. 24). This may represent an intritacalx, an outer shell layer known in Muricidae and several other families,
including Cancellariidae (D'ATTILIO & Radwin, 1971). This microsculpture is practically absent on exposed parts
of the shell, such as the spiral cords, and this observation agrees with the softness of intritacalx layers. The fact
that a similar pitted layer is also present in related species ( B . kaiensis. B. spec. A, B. spec. B) might indicate that
this is indeed an intritacalx with possibly taxonomic value, rather than an accidental corrosion present on the
teleoconch but not on the protoconch. This type of intritacalx structure has not yet been described in
Cancellariidae.
Measurements of intact protoconchs (mean and standard deviation, n = 14): number of whorls, 1.17, 0.24;
maximum diameter, 0.74, 0.08 mm; exposed height, 0.59, 0.10 mm.
The name Solutosveltia abyssicola is based on shells with an aberrant aperture and may well be a synonym of
B. fischeri. A shell from KARUBAR: stn DW 28 (Fig. 17) seems to be intermediate between B. fischeri and
5. abyssicola (Fig. 64). The genus Solutosveltia is based only on the presence of a semidetached aperture, a
character of doubtful taxonomic value.
The elongated form of Brocchinia fischeri is similar to that of B. clenchi Petit, 1986, from the Atlantic, which
has a much weaker sculpture and no pitted shell surface. B. exigua (Smith, 1891) from off southeastern Australia
has a less constricted suture, lacks the pitted shell surface, has 2 spiral cords per whorl, and only one weak
columellar fold.

Brocchinia fischeri belongs to a group of closely related species, occurring both as fossil and Recent in
the Pacific from Japan to New Zealand, and also in the Atlantic including Europe, and which have been classified
under various generic names. Brocchinia was introduced for a European tertiary fossil; Inglisella Finlay, 1924,
Anapepta Finlay, 1930, Gergovia Cossmann, 1899, Microsveltia Iredale, 1925, Solutosveltia Habe, 1961, etc.
have been proposed for Indo-Pacific, Australian and New Zealand species.

Description. — Shell small, globose, spire angle 65°. Protoconch paucispiral, somewhat eroded, with about
1.5 whorls with impressed suture, maximum diameter 0.8 mm, exposed height 0.7 mm (Figs 25-26). Transition
to teleoconch eroded. Teleoconch of about 2 3/4, rapidly expanding whorls. Axial sculpture practically absent on
first whorl; 9 indistinct broad rounded ribs on second and last whorls. Spiral sculpture consisting of 3 spiral bands
on first two whorls, width about 0.1 mm, remaining equal in strength when crossing over the axial ribs,
almost no nodules formed at intersections. Whorls convex, suture lined by a very narrow and shallow canal.

A. VERHECKEN
Aperture semicircular; outer lip crenulated, no inner lirae, only broad grooves corresponding to spiral bands on
outer surface of last whorl. Columella straight, short, with a moderately strong fold and a fainter one forming the
rim of the wide siphonal canal. Narrow zone of thin columellar callus; no umbilicus, no siphonal fasciole.
Dimensions: 4.4 x 4.3 mm.
REMARKS. — B. kaiensis also has a pitted shell surface between the spiral bands. The general outline is
intermediate between B. tanimbarensis and B. fischeri. From B. tanimbarensis, B. kaiensis differs by having
distinct spiral bands, also in interspaces between axials, no sutural ramp and practically no nodules at intersection
of axial and spiral sculpture. B. fischeri is much more slender than B. kaiensis, its protoconch is more depressed,
its columellar folds and callus are much stronger, and it has a parietal tooth.
ETYMOLOGY. — Named after the Indonesian archipelago of the Kai Islands.

Material EXAMINED. — Indonesia. Karubar, Kai Islands : stn DW 15, 05°17'S, 132041'E, 212-221 m, 1 dd.
Description. — Shell high, conical, spire angle 27°, with straight sides and small aperture. Protoconch
paucispiral with 1 1/4 whorl, nucleus relatively large, whorls smooth and rounded (Figs 27-28), maximum
diameter 0.8 mm, exposed height 0.6 mm. Protoconch wider than adapical part of first teleoconch whorl.
Transition to teleoconch clearly marked. Teleoconch with 5 whorls, the First two with 7 weak, broad axial ribs,
subsequent whorls without axial sculpture apart from strongly prosocline growth lines. Spiral sculpture of
3 narrow bands on spire whorls, grouped in abapical two thirds of whorl. Younger whorls flush, suture very
slightly grooved. Base with 4 spiral bands getting weaker abapically. Last whorl with 13 spiral bands. Teleoconch
surface pitted. Aperture rounded, triangular. Outer lip expanded abapically, with 8 strong lirae inside at some
distance from edge. Columella short, inclined adaxially, with 2 strong folds and a weaker one at rim of short
siphonal canal. One parietal tooth. Columellar callus expanded into a solid but thin-edged columellar collar, half
covering a deeply placed umbilical slit.
Dimensions: 9.0 x 3.9 mm.
Remarks. — This single shell is characterised by its elongated, almost perfectly conical shape, differentiating
it from B. fischeri with its rather strongly constricted suture. Already the first teleoconch whorl has the
characteristic flush shape, versus the more rounded whorls of B. fischeri. However, the possibility cannot be
excluded that this shell is only an aberrant form of B. fischeri: it has columellar folds, callus, and parietal tooth
much like it, and the early whorls similarly do have axial sculpture. The loss of axial sculpture might have been
caused by some trauma to the mantle. Protoconch dimensions do not allow a distinction to be made. More material
will be needed to assess whether or not it is a separate species.

a wide siphonal canal.
Dimensions: 6.1 x 3.5 mm.

FIGS 31-32. — Brocchinia tanimbarensis sp. nov., protoconch of juvenile shell from stn CP 71, 477-480 m.
Scale bar: 0.5 mm for all figures.
Remarks. — This single shell differs from B. fischeri in its broader spire angle, relatively higher aperture, and
somewhat less convex whorls. The columellar folds of B. fischeri are much stronger and are placed more
transversely. This shell can be considered to be subadult, with incompletely formed aperture, but even then the
difference in strength of columellar folds still holds. In a specimen of B. fischeri (Fig. 18) the columellar folds can
be observed through a boring hole in the last whorl and, although not as bold as in a normally formed aperture,
they are much sharper than in Brocchinia sp. B, where they are very much like those of B. kaiensis. The
protoconch and the sculpture of the teleoconch, however, are very near that of B. fischeri. Therefore, recognition of
this single shell as a different species is not straightforward, and more specimens will be needed to confirm it as a
separate, undescribed species.

Type LOCALITY. — Indonesia. Off Tanimbar Islands, Karubar, stn CP 77, 08°57'S, 131°27’E, 346-352 m.
DISTRIBUTION. — Known only from off the Tanimbar Islands.
DESCRIPTION. — Shell small, solid, white, with short spire, spire angle 60-80°. Protoconch (strongly eroded
on most shells, preserved only on the smallest one but already with corroded surface, Figs 31-32) paucispiral with
3/4 whorl, surface sculpture etched, maximum diameter 0.9 mm, exposed height 0.6 mm, transition to teleoconch
indistinct. Possibly, a quarter whorl with only smooth sculpture of 2 spiral lines may also be part of the
protoconch. Teleoconch with up to about 3 1/8 whorls. Sculpture starts on the first teleoconch whorl with
3 smoothly indicated spiral lines, undulating to form 8 gradually stronger nodules. Three spirals on spire whorls,
6 on last whorl. Axial sculpture of broad rounded ribs, 10 and 1 1 on second and third whorl, 13 on last whorl.
Shell sculpture prominent at intersection of axials and spirals, forming strong raised rounded nodules. Whorls with
a flat narrow sutural shelf. Aperture semicircular, columella parallel to shell axis, with two rather strong folds, the
weaker abapical fold on the rim of broad short siphonal canal. Outer lip thin, wavy because of nodulose sculpture,
no inner lirae. Thin white columellar callus; no umbilicus nor siphonal fasciole.
Dimensions: holotype 6.5 x 5.5 mm; paratypes up to 7.4 mm.
Remarks. — None of these specimens has a pitted shell surface like B. fischeri, but most of them have spo¬
radic remains of a soft white layer, possibly an intritacalx. The Recent Oamaruia deleta Finlay, 1930, of which
only the juvenile holotype has been figured, reaches 1 1 mm and has 3 distinct columellar folds, the lowest being
stronger (POWELL, 1979: 224). It may be the closest living relative of B. tanimbarensis. Oamaruia major
Marwick, 1965, from the Opoitian (Pliocene, Piacenzan) of New Zealand is also rather close to B. tanimbarensis
but differs by its size up to 11.3 mm, its sculpture with only 2 spirals on spire, its more elongate aperture and
3 columellar folds. The New Zealand Miocene Admete suteri Marshall & Murdoch, 1920, type species (OD) of
Oamaruia Finlay, 1924, has a protoconch of two whorls, "the apex obliquely disposed", 17-21 axials on the last
whorl, and also has 3 columellar folds. Waipaoa marwicki Dell, 1956, from off New Zealand, depth about 600 m,
in general form resembles small specimens of B. tanimbarensis, but lacks the columellar folds and the nodulose
sculpture. B. tanimbarensis is rather different from B. fischeri and the closely related B. exigua from New South
Wales, that share with it the general form of the aperture and columella, but lack the strong nodulose sculpture and
are much more elongate. B. tanimbarensis resembles closely the Atlantic species B. nodosa (Verrill & Smith
in VERRILL, 1885) and B. azorica (Bouchet & Waren, 1985). B. nodosa is much larger (up to 16 mm: MNHN
specimen from Bay of Biscay), and also B. azorica may grow somewhat larger. B. nodosa and B. azorica differ from
B. tanimbarensis in having no distinct sutural ramp, the nodules more pointed, and the columellar and parietal
callus thicker so that the underlying sculpture is barely visible. B. pustulosa Verhecken, 1991a, from off Brazil,
637 m, has a sutural area comparable to that of the new species, grows up to 1 1.6 mm high, and has a much
higher spire.
Etymology. — Named after the Indonesian archipelago of the Tanimbar Islands.

Type Material. — A confusion about the "type lot" of this species asks for some explanation. The shell
figured by SOWERBY was "in Mrs. Mawe's collection", but no shell in BMNH has a label indicating that origin.
Garrard (1975: 4) mentioned "Holotype unknown. ... Location of type: BMNH. Not located at present" and
I (VERHECKEN, 1986: 40) myself stated "there is no indication that this specimen is, or should be, in BMNH".
However, PETIT & Harasewych (1986: 442) mention a type lot BMNH 1968387 of 3 specimens, "labeled
C. elegans, Baclayon, Bohol Id., Philippines on the back of an old board", stating that "it is possible that two
specimens with locality data were added later, as only one specimen has an old label with the number '4', the same
sort as used by SOWERBY, glued inside the aperture". About 15 years ago one of these 3 shells was labelled
"Awaiting neotype selection by Petit", a designation which has never been published. Furthermore, SOWERBY's
figure has the number "3", not "4". This material has now been checked again (vi- 1995) and discussed with
K. Way (BMNH). Of the 3 shells, the one (33.6 x 22.7 mm) once intended for neotype selection resembles best
but is broader than SOWERBY's figure (33.5 x 20.8 mm), and shows no traces of a label having been glued inside
the aperture, although there is an old label with the species name in SOWERBY's handwriting (fide K. Way). That
shell now has a label "Although there is no evidence that this specimen reached Cuming via Mrs. Mawe; its very
close similarity to the type figure and Sowerby's own hand on the label must make it eligible to be considered as a
possible type. K. Way, 1986". Since there is no solid proof that this is the figured shell, its designation as
lectotype would pose a problem; and because it has no reliable locality data, it does not qualify for selection as a
neotype. I suggest the best solution would be to select as neotype a well documented shell resembling as closely
as possible this BMNH shell, when such specimen can be found.
Type Locality. — Unknown to SOWERBY (I). Ticao, Philippines, according to G. B. Sowerby (II) (1849:
447), possibly based on 4 shells ex Mrs De Burgh coll. (BMNH).
Distribution. — Philippines; Indonesia.
Remarks. — Within the genus Merica, M. elegans is characterised by its numerous weak prosocline ribs,
only very slightly canaliculate suture, and slightly inflated fusiform outline. The present specimen (30.4 x
18.8 mm) is more slender than Merica melanostoma Sowerby, 1849, and M. subsinensis Loebbecke. 1881. Its
suture is less canaliculate, and its sculpture is dominantly spiral, much more like that of Merica sinensis Reeve,
1856, which however has a strongly oblique protoconch. The species described and illustrated by Garrard [1975:
3, fig. 1(1)] as Cancellaria (Merica) elegans and occurring subtidally down to 49 m off NE Australia (including
Gulf of Carpenteria, near the Arafura Sea) to Queensland, differs markedly from the present material.

Distribution. — Japan to Indonesia; Northern Indian Ocean to Aden; Eastern South Africa (?) (Verhecken,

REMARKS. — Specimens in collections are usually smaller in size [heights of 43 mm (Loebbecke Museum
und Aquarium, Diisseldorf) and 37 mm (VERHECKEN, 1986: 42) are exceptional] and have a much smoother
sculpture. The coarse sculpture of present specimens resembles that of M erica laddi Petit, 1987 [= Cancellaria
(Merica) petiti Ladd, 1982, non Olsson, 1967], from the Pliocene of Fiji, which is smaller and has a more
acuminate spire.
Genus MICROSVELTIA Iredale, 1925
Microsveltia Iredale, 1925: 265. Type species (OD): Microsvellia recessa Iredale, 1925. Recent, New South Wales,
Australia.
Garrard (1975: 35) considers Microsveltia a synonym of Gergovia Cossmann, 1899, because Cancellaria
platypleura Tate, 1898, type species (OD) of Gergovia "was almost certainly ancestral [to M. recessa], and the
introduction of a new genus was unwarranted". However, COSSMANN originally included Gergovia in Merica as a
new section; and M. recessa has very little resemblance to any species of Merica. Hence, this synonymy is not
accepted here, and Microsveltia is considered valid. FINLAY (1930: 241) considered Microsveltia to be "an absolute
synonym" of Inglisella; but the Brocchinia- like species included in Inglisella do not seem closely related to
M. recessa. Inclusion of the following four species in Microsveltia is only provisional, awaiting a thorough
revision of the cancellariid genera.

DESCRIPTION. — Shell small, with relatively high, conical spire and small aperture, whorls bicarinate, suture
well impressed. Protoconch (severely corroded in all shells) apparently paucispiral and rather high, not flattened.
Teleoconch with up to about 5 whorls. Axial sculpture of rather narrow rounded ribs, constricted near suture,
numbering 7-10, 9-11, 11-13, 11-15 on 2nd to 5th whorl respectively; base without axial sculpture. Spiral
sculpture of narrow cords numbering 2, 3-4, 3-4 on second to fourth whorl, 10-12 on last whorl, including
secondary spirals. Whorls rounded, angular at main spirals, constricted near deeply impressed suture. Aperture
small, oval, ending abapically in short but distinct siphonal canal. Columella short, with one strong fold and a
very weak one at the start of the siphonal canal, which is slightly inclined adaxially. Outer lip crenulate; no lirae
inside. Siphonal fasciole slightly developed. No umbilicus, only a slight, completely closed, depression. Almost
no columellar callus. Thin pale fawn periostracum.
Dimensions: holotype 9.9 x 5.8 mm. Paratypes 7.6 x 4.6 mm (MNHN); 5.6 x 3.6 mm (POLIPI).
Remarks. — The constricted profile of the whorls resembles that of M. metivieri, but the latter species has
much broader ribs. The sculpture somewhat resembles that of Cancellaria patricia Thiele, 1925, from East Africa
(type locality) and south-eastern Australia (Verhecken, 1991b), but that species has much weaker columellar
310
A. VERHECKEN
folds and a shorter spire. M. recessa has a reticulated sculpture much stronger than in M. karubar , moreover it has
two columellar folds of about the same strength, a small and narrow umbilicus, partly covered by callus, and a fine
bristly greenish-brown periostracum (Garrard, 1975: 37).
ETYMOLOGY. — This species is named after the French-Indonesian scientific expedition that discovered it.

Type Locality. — Indonesia. Off Kai Islands, Karubar, stn DW 28, 05°31'S, 132°54'E, 448-467 m.
Description. — Shell small, white, with acuminated spire, spire angle 55°, and strongly constricted suture.
Protoconch (Figs 41-42) white, paucispiral with one whorl, slightly deviating from teleoconch axis, nucleus
relatively large, diameter 0.3 mm, suture slightly impressed. Maximum diameter 0.6 mm, exposed height
0.5 mm. Transition to teleoconch rather indistinct. Teleoconch with 4 3/4 whorls. Axial sculpture consisting of
strong, broad rounded ribs, far less prominent near suture, numbering 8, 8, 9, 11 on 1st to 4th whorl respectively,
12 on last whorl. Growth lines microscopic, hardly visible. Spiral sculpture of well-marked cords, width up to
0.1 mm, numbering 2, 2, 3, 5 on 1st to 4th teleoconch whorl respectively, 11 on last whorl. The spirals keep
their profile when crossing over the axials, without nodular intersection. Spiral cords more closely set in adapical
two-third of whorls, thus giving the impression of a slightly excavated suture, but in younger whorls a much
narrower spiral cord appears just above abapical suture. Last whorl regularly convex; axial sculpture disappearing
towards umbilicus. Aperture rounded, columella straight, inclined adaxially, with two weak folds, anterior one
weaker. Siphonal fasciole well developed, enclosing a narrow umbilicus which is almost closed by a thin
columellar callus. No lirae inside outer lip. Short, broad siphonal canal.
Dimensions: 6.3 x 3.8 mm.
Remarks. The sculpture of strong ribs of M. metivieri superficially resembles the much stronger sculpture
ol Scalptia mercadoi Old, 1968, from the Philippines, but that species has a multispiral protoconch and grows up
to 34 mm (AV) for 6 teleoconch whorls, or 18 mm for 4.5 whorls. M. metivieri is rather close to, but different
Irom M. recessa Iredale, 1925, from New South Wales, Australia, which has bicarinate whorls with nodules on
intersections of coarse spiral and axial sculpture, "microscopic hair-like growth lines", and 8 lirations inside outer
lip (Garrard, 1975: 37).
Etymology. — This species is named in honour of Bernard Metivier (MNHN).

0.7 mm, exposed height 0.6 mm. Transition to teleoconch not discernible because of shell damage in that area.
Teleoconch with about 4 whorls. Axial sculpture consists of rather narrow, slightly opisthocline rounded ribs, 12,
1 1, 10 and 1 1 on 1st to 4th whorl respectively. Spiral sculpture of narrow threads, 2, 3, 3 + 1 secondary, on 1st to
3rd whorl, 10 on last whorl, crossing over axials without nodules. Aperture rounded, trapeziform, with short, wide
siphonal canal; outer lip thin, without inner lirae. Columella short, parallel to shell axis. One very weak
columellar fold in holotype (Fig. 45); paratype (Fig. 46) with a relatively strong fold, and a weak one at rim of
siphonal canal which deviates adaxially from the columellar direction. No umbilicus, no columellar callus.
Siphonal fasciole not developed. Shell covered by thin pale-beige periostracum, forming microscopic axial folds
which apparently do not reflect the presence of a similar sculpture on shell surface.
Dimensions: holotype 5.0 x 2.6 mm; paratype 6.0 x 3.0 mm.
REMARKS. — Microsveltia procerula is close to M. cf. sagamiensis, but differs by its thin shell, its less
constricted suture, its sutural area sloping down towards shoulder of whorl, and its stronger columellar folds.
It differs from M. metivieri in its less conical spire, and the strength and form of its axial ribs. M. procerula
closely resembles Cancellaria turriculata Tate, 1889, from the upper Eocene of South Australia, judging from the
original description and illustration (TATE, 1889: 156, pi. X, fig. 14), but conspecificity can be excluded because
of the very large gap in time.
ETYMOLOGY. — The specific name is from the Latin adjective procerulus, diminutive of procerus , meaning
"rather long, elongate", and refers to the slender form of this small shell.

Type Material. — The illustrated syntype of Neadmete sagamiensis (6.3 x 3.3 mm) is here designated
lectotype; it is in the collection of the Emperor of Japan, together with at least 3 paralectotypes (not seen).
TYPE Locality. — West of Jogashima, Sagami Bay, Japan, 1 10-150 m.
DISTRIBUTION. — Japan: from Sagami Bay, Honshu and Tosa Bay, Shikoku, sandy bottom, 50-200 m.
Description. — Shell minute, solid, elongated, spire angle 50°, constricted near suture, aperture small.
Protoconch bulbous, paucispiral with about 1 whorl, suture impressed (Figs 55-56). Maximum diameter about
0.6 mm, exposed height 0.5 mm. Remains of a finely granular microsculpture still present (Fig. 57). Transition
to teleoconch not discernible because of shell damage in that area. Teleoconch with about 3.5 shouldered whorls.
Axial sculpture of rounded ribs, narrow on first, broadly rounded on later whorls, 10, 9 and 10 on 1st to
3rd teleoconch whorl, 7 on last whorl. Spiral sculpture of narrow (up to 0.1 mm wide) cords running over the
axial ribs without forming nodules, 2 cords on 1st whorl, 2 + 1 secondary spiral and 1 on shoulder plane on
2nd whorl, 3 + 2 on shoulder plane on 3rd whorl. The zone between suture and the first adapical spiral cord is
wider than the spiral interspaces. Last whorl with 1 1 narrow, well-marked spiral cords. Suture strongly constricted,
sutural area almost horizontal and slightly wavy because of vanishing axial ribs; shoulder of axial ribs produced in
a rounded angle. Aperture small, rounded triangular. Outer lip with thin edge (partly broken) and 5 widely spaced
rather indistinct inner lirae continuing deep inside aperture. Columella straight, with 2 very weak folds deep inside
aperture. Short, broad siphonal canal. Columellar callus narrow and thin, but covering most of the umbilical slit.
Almost no siphonal fasciole. No periostracum.
Dimensions (Karubar specimen): 4.25 x 2.5 mm.
REMARKS. — Petit (1974: 1 1 1) considered Neadmete sagamiensis to be a synonym of Admete cancellata
Kobelt, 1887, described from Japan, and said to have 'narrow high radial ribs', narrower than their interspaces, and
crossed by spirals of about the same strength, forming a neatly quadratic cancellation (KOBELT, 1887a: 12;
1887b : 105). Kobelt's illustration (1887b: pi. 24, fig. 14) is so small that it can hardly be used for
identification, but the sculpture described is very obvious on the type [holotype by monotypy, ICZN art. 73a(ii),
see KOBELT, 1887b; 10.2 x 6.2 mm, ZMHU 101677, Fig. 63]. The dimensions of the holotype and of its
paucispiral protoconch (1 1/8 whorl, max. diameter 0.95 mm, exposed height 0.8 mm) are significantly larger than
in the present material; and the sculpture is quite different, so that identification of the Karubar shell as
A. cancellata is rejected. Both the Karubar shell and the lectotype of Neadmete sagamiensis (according to the
original illustration) have axial ribs broader than their interspaces and much stronger than the spirals, and the
whorls are more shouldered than the regularly rounded whorls of A. cancellata. Therefore, PETIT's identification of
N. sagamiensis as Admete cancellata does not seem completely warranted, but variability within these taxa is as
yet unknown. Since the present specimen is certainly different from the holotype of A. cancellata and closest to
M. sagamiensis, the latter name is used here. The Karubar specimen differs from the lectotype of
N. sagamiensis in having the whorls more shouldered and the aperture more triangular. The protoconch of the
lectotype, according to KURODA & Habe's description and illustration, is larger and has more whorls. Because of
these differences, identification of the present material is only tentative. M. cf. sagamiensis is quite similar to
M. metivieri but differs in having the whorls more shouldered, a wider and flatter sutural area, the axial ribs less
pronounced, the whorls less convex, and the columellar folds much weaker.

Published illustrations of M. recessa from New South Wales, Australia are somewhat contradictory, drawings
of the holotype (Iredale, 1925: pi. 43, fig. 16; LASERON, 1955: 268, fig. 11) resembling the present shell
except lor the 2 strong columellar folds, but photographs of the holotype [Garrard, 1975: fig. 3(8)1 and other
specimens [Garrard, 1975: fig. 3(7); Ka.cher, 1978: card 1919] showing a very coarse quadratic sculpture.
. recessa has two bold and narrow spiral cords, forming prominent lateral nodules at junction with ribs, and
strong hrat'ons mside the outer lip (Garrard, 1975: 37). In general form and in the sculpture of broad axial ribs
overridden by narrow spiral bands, M. sagamiensis seems also to be close to Cancellaria japonica Smith, 1879
but extensive damage to the latter's holotype (1 1.9 x 5.8 mm, BMNH 1878.1 1.7.90, figured by Petit, 1974: 1 lo’
text-fig. 3) prevents clear conclusions. Subsequent to the original description, no additional specimens of
^japonica have been reported; it could not be recognised as any known Japanese species by Habe and by
Okutani (Petit, 1974: 1 10). Hence, its real relation to M. sagamiensis remains unclear.
Kuroda & Habe (1971) placed sagamiensis in the genus Neadmete Habe, 1961. Its type species (ICZN
Opinion 1370), N. okutanu Petit, 1974, has a dominantly spiral sculpture (see Habe, 1961: pi 23 fig 11
incorrectly identified as Neadmete japonica, later renamed N. okutanii). The genus has been used for several rather

Perplicaria has been known only from five fossil species in the Caribbean and France, and one Recent species
(Perplicaria clarki M. Smith, 1947) from West Central America. The genus ranges from the early Miocene
(Perplicaria prior Maury, 1910) to Recent.

TYPE Locality. — Indonesia. Tanimbar Islands, Karubar, stn CP 79, 09°16'S, 131°22'E, 239-250 m.
DESCRIPTION. — Shell outline typical for a Perplicaria. Protoconch whitish, paucispiral with one rapidly
expanding whorl (Figs 49-50), maximum diameter 0.9 mm, exposed height 0.8 mm. Surface smooth and shiny,
last 1/16 whorl showing a smoothly indicated start of spiral sculpture. Transition to teleoconch clearly marked by
an expansion of shell width and the beginning of strong teleoconch sculpture. Teleoconch with 2 3/4 whorls,
rapidly expanding in height. On first half whorl only spiral sculpture of 7 low Hat bands. On second whorl
36 gently indicated axial ribs, and 1 1 primary spiral cords, with one narrower second order spiral in between. Last
whorl with 19 broad spiral cords, second and third order spirals in between. On last whorl, axial ribs have
practically disappeared. Axial ribs and growth lines opisthocyrt. Whorls rounded, suture impressed. Inclination of
whorls steeper than inclination of spiral bands. Aperture oblong, 54 % of total shell height, slightly expanded
abapically. Outer lip solid, with narrow and slightly crenulated edge, 15 lirae inside. Columella straight, with
3 folds, adapical one strongest, abapical fold forming rim of short siphonal canal. No umbilicus, only a very
narrow slit is present. Columellar callus thin, almost completely covering the umbilical slit. Colour pale fawn,
inside of aperture white, with an indistinct colabral pale orange band near base of lirae.
Dimensions: 9.0 x 4.5 mm.
REMARKS. — P. boucheti represents the first Perplicaria known from the Eastern hemisphere, and the second
known living species of the genus. Perplicaria clarki differs in having a multispiral protoconch (as ascertained
based on a shell from Gobernadora Island, Panama, AMNH 253840), and adult size reaching 33 mm (Keen, 1971 :
656). Based on analogy with the other species of this genus, the holotype of P. boucheti may not be fully grown.
ETYMOLOGY. — This species is named in honour of Philippe BOUCHET (MNHN).
Genus SOLATIA Jousseaume, 1887
Solatia Jousseaume, 1887: 222. Type species (OD): Solatia solat Jousseaume, 1887 (junior subjective synonym of
Solatia piscatoria Gmelin, 1789. See Verhecken, 1988: 665), North-west Africa.
This genus groups mainly European fossil and two Recent species in the eastern Atlantic (VERHECKEN, 1988).
Only Solatia buccinoides (Sowerby, 1832) from tropical West America has also been placed in Solatia (KEEN,
1971: 654), but this placement is questionable.

Type Material. — Holotype lv, MNHN.
Type Locality. — Indonesia. Off Tanimbar Islands, Karubar, stn CP 72, 08°36'S, 131°33'E, 676-699 m.
Distribution. — Type locality, and off Port Hedland, north Western Australia (Wilson, 1994; material not
examined).
Description. — Shell large, solid, oblong, strongly sculptured; last whorl elongated. Protoconch missing,
early teleoconch whorls strongly corroded. Teleoconch axial sculpture of strong, broad rounded ribs, interspaces
about as wide as ribs, 13, 15, 16 on spire whorls, 16 on last whorl. Spiral sculpture of broad rounded cords,
smoothly indicated, 4 per whorl, plus one on shoulder of whorl, fused onto nearest cord. Intersection with axials
strongly nodular. Suture impressed, forming a narrow concave sutural area, bordered by strong nodules on shoulder
of ribs and obliquely crossed by strong growth lines. Aperture white, oblong, ending abapically in a well-defined
siphonal canal. Columella straight, parallel to shell axis, two rather strong columellar folds placed near half
height. Columellar callus thin, transparent, covering almost completely narrow umbilical slit. Outer lip slightly
crenulated, no lirae inside.
Dimensions: 36.0 x 20.1 mm.
Remarks. — Except for two recently formed sections of the last whorl, the shell surface is heavily corroded
and chalky. In spite of this, aperture interior is intact and smooth, and the specimen was live-taken. Large parts of
the shell surface were covered by a black layer (about 0.5 mm thick, still partly visible on Fig. 51) with the aspect
of bitumen, which however does not dissolve in acetone or dichloromethane, usual solvents for bituminous
substances. It might be periostracum, or remains of an epibiont. The last section of the last whorl, where shell
dissolution must have been minimal, had very little of this layer: this seems to point out an epibiont rather than
periostracum.
This species is close only to Solatia buccinoides (Sowerby, 1832) from tropical West America, which grows
up to 40 mm, has a brown shell, much stronger spiral sculpture, and sutural area sloping down towards shoulder.
S. buccinoides also has a wider aperture, the outer lip expanded near half height with 1 1 lirae inside, and a posterior
canal. The two columellar folds are stronger than in S. arafurensis. Placement of this new species in Solatia is by
reference to S. buccinoides, since there seems to be no better fitting genus.
This is clearly the species mentioned and illustrated by WILSON (1994), who gives the following information:
"4 cm. North West Shelf. This unidentified species has been trawled recently on the scampi grounds on the outer
edge of the continental shelf off Port Hedland".
Etymology. — Named after the Arafura Sea, where the holotype was collected.

Type Material. — Lectotype, here designated, the shell figured by Thiele, 3.7 x 2.4 mm. Paralectotypes:
10 specimens, "Valdivia", stn 251, 01°40.6'S, 41°47.1'E, 693 m, and 2 specimens, "Valdivia", stn 256, 01°49’N,
45°29.5'S, 1 134 m. All types are in ZMHU; no registration number. Paralectotype 10 (3.5 x 2.0 mm, lv) is quite
different and resembles the turrid Propebela exarata (Moller, 1842) from Greenland, as illustrated by SNELI &
Stokland (1986: 122, fig. 2).
TYPE Locality. — Eastern Africa. Off Somalia, "Valdivia", stn 251, 01°40.6'S, 41°47.1'E, 693 m.
Distribution. — Off Somalia, 693-1 134 m; now the Arafura Sea, 480 m.
DESCRIPTION. — [KARUBAR specimen) Shell small, thin-walled, semi-translucent, whitish; spire short.
Protoconch smooth, paucispiral, with about 1 1/8 whorl, maximum diameter 0.7 mm, exposed height 0.5 mm
(Figs 58-59). Nucleus relatively large, diameter 0.26 mm. Transition to teleoconch only marked by start of axial
teleoconch sculpture. Teleoconch with 3 slightly inflated whorls, suture impressed, last whorl large, height
4.0 mm (77 % of total shell height). Axial sculpture on 1st to 3rd whorl consisting of respectively 13, 12,
12 smoothly indicated, slightly sigmoid rounded ribs, disappearing near shell base. One rather strong spiral cord
on shoulder, forming nodular intersection with axials, adjacent to somewhat concave spiral depression. Smooth
spiral bands, width 0.1 mm, numbering 6 on 2nd, 14 on last whorl, separated by narrow groove, crowded towards
shell periphery and base. Shoulder area flat, slightly sloping down towards shoulder cord, axials obliquely crossing
over it. Aperture oval, slightly square-cut adapically. Columella straight, almost parallel to shell axis, with 2 very
weak folds near half height; siphonal canal wide and short. Outer lip thin, translucent, no inner lirae. No
umbilicus.
Dimensions: 5.2 x 3.4 mm.
Figs 58-59. — lAdmete aethiopica Thiele, stn CP 71, 477-480 m, protoconch. Scale bar: 0.5 m.
REMARKS. — The lectotype of Admete aethiopica has a dome-shaped paucispiral protoconch of 1 whorl,
maximum diameter 0.7 mm, exposed height 0.6 mm, nucleus large, diameter 0.33 mm. The teleoconch has
2.5 whorls, axial ribs 15 and 16 on 1st and 2nd whorl, 13 on last whorl; 13 spirals on apertural side of last whorl.
Height of aperture 1.9 mm, height of last whorl 3.0 mm. Paralectotypes measure up to 4.4 x 2.7 mm (Thiele
gave 4.25 x 2.5 mm), average 3.8 x 2.3 mm. The double row of nodules near shoulder, as figured by Thiele, is
only clearly present in the five largest shells, and can be even stronger than in the lectotype. It may be a
characteristic of fully grown specimens. The Indonesian specimen, although larger than any of the types, has the
second row only vaguely indicated and has fewer axial ribs than the lectotype. The number of axial ribs in the type
material (excluding paralectotype 10) is 14-16 and 15-16 on the 1st and 2nd teleoconch whorls respectively. The
obtusely angled truncated columella figured by Thiele occurs in most, but not all of the paralectotypes. Also the
318
A. VERHECKEN
strength of the spiral striae is quite variable. Considering all this, and despite the geographic distance, there seems
to be no reason to separate the East African material and the present Indonesian material.
Subsequent to its original description, Admete aethiopica has been mentioned only by PETIT & HARASEWYCH
(1990: 9), stating that Admete aethiopica is "not a cancellariid". This statement was based on a verbal
communication by P. BOUCHET in 1984 (Petit, in litt., June 1995), who considered Thiele's species to be a
juvenile Gymnobela at that time. BOUCHET (in litt., July 1995) now admits that his 1984 opinion was erroneous
and that Admete aethiopica is a cancellariid. Placement of the species in Admete is not certain, but seems the most
appropriate for the time being. THIELE found no radula, and I equally found neither radula nor tubular jaw. Two
perfectly spherical glassy statocysts, diameter 0.1 mm, could be seen by transparency after rehydrating the animal
prior to dissection.

Synonyms: Nivitriton Iredale, 1929, Esbelta Sarasua, 1975 (fide Beu & Maxwell, 1987: 33).
Tritonoharpa differs from Plesiotriton in lacking the prominent columellar folds and (as far as presently known)
a radula. Beu & Maxwell (1987: 33) include 19 Recent species, most of them from the tropical Indo-West Pacific.
Six species of Tritonoharpa are currently known from Indonesia (Bf.u & Maxwell 1987), three of them still
unnamed.

Distribution. — Kai and Tanimbar Islands, southern Moluccas, Indonesia.
DESCRIPTION. — Shell elongate, axial sculpture slightly more prominent than spiral sculpture; aperture long
(45% of total shell length) and rather narrow. Protoconch relatively large, slightly deviating from teleoconch axis,
paucispiral with 1.5 swollen smooth whorls, not planorboid; maximum diameter 1.2 mm, exposed height
1.0 mm. Transition to teleoconch shell clearly marked by sudden start of teleoconch spiral sculpture. Teleoconch
with 5.5 weakly convex whorls. Axial sculpture of narrow, low, opisthocline non-collabral ribs, 16, 17, 18, 25 on
1st to 4th teleoconch whorl, 25 on last whorl. Varices formed at irregular intervals (150°-360°) on spire whorls,
spaced about 240° on adult whorls, not parallel to axial ribs, raised rather high above suture, which is coronated by
axial ribs of the subsequent whorl. Varices reflected and concave on abapertural face. On base, fine growth lines
present between axials. Spiral sculpture of flattened narrow cords, 0.1 mm wide, 8, 8, 8, 10, 10 on 1st to
5th whorl, 34 on last whorl. Three to 6 microscopic spiral lines in spiral interspaces. Spirals form tiny nodules
when crossing axial ribs. Aperture forming a rounded elongated parallellogram, ending adapically in a small sinus.
Outer lip smooth inside, edge crenulated with 16 small nodules, bordered at a distance of 0.5 mm by a strong
varix. The same arrangement can also be seen on older varices, where further shell growth occurred not at the
curled-up edge of outer lip, but somewhat inside it. Inner lip erect, extended into a well developed columellar
collar. Columella almost parallel to shell axis, slightly swollen near centre but without a distinct fold. Siphonal
canal well developed, open and strongly twisted dorsally. Umbilical chink partly hidden by anterior end of
columellar collar. Background colour pale beige; a large brown blotch at mid-distance between two varices, and a

narrow brown band extending over the width of 3 spiral cords on varices, brown elements paler and indistinct on
apical whorls.
Dimensions (holotype): 16.5 x 6.0 mm.
Remarks. — A photograph of the Karubar specimen was submitted to A. BEU (NZGS), who advised that
its presumed identity with Tritonoharpa n. sp. ?C, aff. T. angasi appears to be correct. Beu & MAXWELL (1987:
35) state that it "lacks the interstitial cords of T. angasi". This refers to the secondary spiral cords (BEU, in litt.)
and these are indeed lacking on the holotype. The only difference between holotype and paratype is the slightly
greater inflation of the whorls of the latter. The protoconch of the paratype was figured by Beu & Maxwell
(1987: pi. 12, fig. o).
Distinction of species within Tritonoharpa is not easy. T. beui differs from some of its congeners by its nearly
straight-sided whorls and general shell outline, from others by its microscopic spiral sculpture or by the
protoconch retained in adult specimens (several species are normally decollate at this size). For further
differentiation from other species of Tritonoharpa , see BEU & Maxwell (1987: 35).
etymology. — This species is named in honour of A. G. Beu (NZGS), senior author of the important study
on Plesiotritoninae where this species was figured for the first time and was recognised as a probably new species.
DISCUSSION
The present collection is remarkable in the number of new records and new taxa collected in the somewhat
restricted geographical area covered by the expedition. From the Arafura Sea, only 7 cancellariids had been recorded
in the literature and/or are represented in museum collections: the holotype of Cancellaria nassoides Schepman,
1911 [= Bonellitia garrardi ] from the Kai Islands (ZMA); a specimen of Trigonostoma bicolor (Hinds, 1 843) from
"Samarang" stn 258, Tual, Kai Islands, 22 m (ZMA); a damaged specimen of T. antiquatum (Hinds, 1843) from
approximately 100 miles North of Croker Island, Arafura Sea, 09°30' S, 132°34' E, 124 m (AMS); a specimen of
Neadmete okutanii (identification by T. Garrard) from off W. Aru Island, 54-65 m (USNM 747371); and three
species of Tritonoharpa: T. pseudangasi Beu & Maxwell, T. brunnea Beu & Maxwell and T. aff. angasi, together
represented by 5 specimens. The present material adds 18 additional species, only 3 of which are here well
represented in number of specimens. The total number of cancellariid species known to occur in Indonesian seas is
now 41 (VERHECKEN, 1986; Beu & MAXWELL, 1987; the present study). This compares favourably to other,
much more thoroughly studied, (Indo-) Pacific areas: Australia 48, Philippines 16, Japan 36 species. Among the
new species, some appear to have their closest relative in west central America and the Atlantic Ocean. Faunal
affinities between Plio-Pleistocene molluscs from the latter areas and from western Pacific islands had already been
reported (Ladd, 1982: 19-20).
Another result of the present study is the presence of a shell layer, possibly an intritacalx, which has been
noted in some, but not all species here placed in Brocchinia. Surface layers of this type had not yet been described
in Cancellariidae. Further work will be necessary to evaluate the significance of this character at genus level.

ABSTRACT
Nineteen new species are described from the bathyal zone of the Arafura Sea at depths between 146 and 1084 m. The
genus Lusitanops is recorded for the first time from the Indo-Pacific and Clinura vitrea sp. nov, is the first Recent
representative of this hitherto Cenozoic fossil genus. Based on shell and radula morphology, the classification of
Heteroturris in the Clathurellinae is confirmed. Including new species described here, there are now 92 turrid species
recorded from Indonesia at depths greater than 200 m.
RESUME
Mollusca Gastropoda : Nouveaux Turridae bathyaux (Conoidea) de Test de l'Indonesie.
Dix-neuf esp&ces nouvelles de Turridae sensu lato (= Turridae s. s. + Conidae) sont decrites de la mer d' Arafura, il des
profondeurs comprises entre 146 et 1084 m. Le genre Lusitanops est signale pour la premiere fois de l'Indo-Pacifique, et
Clinura vitrea sp. nov. represente la premiere occurrence dans les faunes modernes de ce genre, jusqu'ici connu comme
fossile du Cenozoique. L'attribution du genre Heteroturris & la sous-famille Clathurellinae est confirmee par la
morphologie de sa radula. Certaines esp&ces nouvelles atteignent de grandes dimensions (par exemple Comitas rex
sp. nov., 87 mm el Nihonia maxima sp. nov., 128 mm), ce qui suggbre que la faune bathyale de Turridae d'Indon6sie
(92 espfeces actuellement recens6es & des profondeurs sup6rieures it 200 m) est encore loin d'etre inventoriee de fa9on
satisfaisante.
INTRODUCTION
Conoidea, or Turridae sensu lato as they used to be known, represent a significant component of deep-water
gastropod assemblages worldwide. Because of the sheer size of the family, and also because many species are
extremely scarce, Indo-Pacific turrids are poorly known. Despite the rich harvest of turrids obtained there by
the landmark “Siboga" expedition one hundred years ago, the fauna of Indonesian waters is no exception.

SCHEPMAN (1913) recorded 52 species, most of them new, from water depths exceeding 200 m in the Indonesian
archipelago. The Karubar expedition, which worked in eastern Indonesia during October and November 1991,
obtained a very rich material of Conoidea, comprising over 100 species. Work on this collection is in progress and
the results will greatly extend our knowledge of the deep-water Indonesian fauna. The purpose of the present paper,
which is a preliminary report on this turrid fauna, is to record and describe some of the more spectacular new
species collected during the expedition. Twenty new species are described from 19 deeper- water stations, at depths
between 146 and 1084 m. They belong to 15 genera.
Type material is housed in Musdum national d'Histoire naturelle, Paris (MNHN) and Pusat Penelitian dan
Pengembangan Oseanologi LIPI, Jakarta (POLIPI).

Largest paratype 22.2 x 5.7 mm. Diameter/height ratio of intact shells 0.26-0.30, mean 0.28.
Paratypes very similar to holotype, differing only in details of spiral sculpture. Subsutural fold on last whorl
occasionally with 1 additional thin thread in its lower part, cords below keel may number up to 4, and two
paratypes have a thin cord in 1 interspace between main cords on shell base. Also, in some paratypes, the
subsutural ramp may have numerous, rather strong, oblique growth lines.
REMARKS. — Gemmula closterion is one of the smallest species in the genus. I cannot ascertain that the
specimens examined are adult, but this is likely since shells from 3 different stations are of about the same size.
328
A. SYSOEV
Even if the type specimens are subadult, the species is nevertheless easily recognizable by its paucispiral
protoconch, a character so far unique in Gemmula s. str., which indicates that the species has non-planktotrophic
development (probably lecithotrophic). The most similar species is G. graeffei (Weinkauff, 1875) (- G. hombroni
Hedley, 1922), which differs in having a uniformly brown shell, a non-channeled suture, spiral ribs on the entire
subsutural ramp area, and a typical multispiral protoconch. A similar, paucispiral protoconch occurs in the
subgenus Kuroshioturris Shuto, 1961, which differs from the nominotypical subgenus by numerous conchological
characters.
Etymology. — From the Greek kloster , spindle; klosterion is a diminutive. It is treated as a noun in
apposition.

Type Material. — Holotype MNHN.
DIAGNOSIS. — Shell large, 87 mm high, fusiform, spire height comprising 40% of shell height, with long
and broad canal. Color of periostracum light brown, with abapically to whorl periphery a band of dark reddish-
brown rectangular blotches on axial ribs. Whorls strongly angulate, with wide concave subsutural ramp covered by
very fine spiral threads. Suture shallow. Axial ribs very strong, widely spaced, oblique, gradually weakening
towards base ol last whorl. Spiral sculpture of strong, rounded and widely spaced cords, occasionally with
additional secondary cord in interspaces. Interspaces covered by 2-4 fine spiral threads. Cords equally strong on
axial ribs and between them. Anal sinus deep, wide and rounded, deepest point just below middle of subsutural
ramp. Outer lip projecting forward below sinus.
Description (holotype). — Shell solid, elongate fusiform, with a high turreted spire consisting of 13.5
whorls strongly angulated somewhat above periphery, with a wide, concave subsutural ramp. Protoconch and first
2-3 teleoconch whorls eroded, but protoconch probably paucispiral. Suture well defined, shallow, straight. Axial
ribs very strong, rather sharp, widely spaced, opisthocline, produced adapically without forming a knob, entirely
traversing spire whorls, gradually weakening abapically, abruptly stopping on shell base; 10 on penultimate whorl
and 8 on last whorl. Subsutural ramp covered by very fine and closely set spiral threads. Spiral cords below ramp
coarse, rounded, equally strong on axial ribs and between them; interspaces broader than cord, with 2-4 coarse
threads and occasionally an additional secondary cord. Base almost flat, smoothly continuous with canal. Canal
long, proportionally very broad, and slightly curved adaxially. Inner lip of aperture weakly and rather evenly
concave, with thin, longitudinally rugose callus. Outer lip projecting moderately forward below sinus. Anal sinus
deep, wide and rounded, deepest point just below middle of subsutural ramp. Shell covered by thin, firmly attached
light brown periostracum, with abapically to whorl periphery a reddish-brown band forming distinctly darker
rectangular blotches on axial ribs, most clearly visible on wet shell.
Dimensions: height 87.1 mm, last whorl height 52.3 mm, aperture height 42.7 mm, diameter 27.5 mm.

Remarks. — The sculpture and general colour pattern resemble those of C. ilariae Bozzetti, 1991, but
Comitas rex clearly differs by having angulate whorls with stronger axial ribs and concave subsutural ramp, and
much broader canal. Another similar species is C. kaderlyi (Lischke, 1872), which, however, is characterized by
more numerous and weaker axial ribs and finer spiral sculpture.
Etymology. — From the Latin rex, king, with reference to the large size of the species. It is treated as a
noun in apposition.

MATERIAL EXAMINED. — Indonesia. Karubar, Tanimbar Islands: sin CP 84, 09°23'S, 131°09'E, 246-275 m,
1 dd (holotype).
Type Material. — Holotype MNHN.
Diagnosis. — Shell large for genus, over 120 mm high, slender, fusiform, spire rather high, comprising 35%
of shell height. Suture shallow. Spiral sculpture of narrow, granular cords in the slightly concave substural ramp,
and rather weak and widely spaced primary cords below the shoulder. Interspaces with thinner secondary cords and
thin, wavy, and closely set tertiary ones. Aperture narrow, canal long and straight. Anal sinus deep, asymmetrical,
outer lip strongly projecting forward below sinus. Colour yellowish-white, with reddish-brown primary spiral
cords.
DESCRIPTION (holotype). — Shell solid, slender, fusiform, with relatively high spire comprising 35% of shell
height. Protoconch and tip of teleoconch missing. Teleoconch consisting of 10.5 whorls, adapical 3 whorls
styloid, with very slow increase in diameter. Suture tightly adpressed, sometimes hardly distinguishable, clearly
lined on spire whorls by a narrow, strongly granular subsutural cord, which becomes rather obsolete on last
2 whorls. Subsutural ramp concave, especially on juvenile whorls, less so on adult whorls. Spiral sculpture of
spire whorls consisting of thin cords on the subsutural ramp, a broader cord bordering abapically the subsutural
ramp, and 3 (later 2) strong cords below whorl periphery. On subsequent whorls sculpture becoming more
complex. Cords in subsutural ramp fading out until only three indistinct ones remain in the middle of subsutural
ramp of last adult whorl. Secondary and wavy, closely set tertiary spiral cords appearing gradually in interspaces
between main cords. On periphery and base of last adult whorl, sculpture consisting of 4 single and 2 twinned
flattened, rather weak primary cords. No axial sculpture except numerous strong incremental lines intersecting
spiral cords, spiral cords sometimes interrupted at intersections, especially on canal. Aperture rather narrow, ovate,
smoothly continuous with long, straight canal. Inner lip covered by thin callus. Outer lip thin, strongly projecting
forward below anal sinus. Sinus deep, asymmetrical, deepest part in abapical half of subsutural ramp. Colour
yellowish-white, with reddish-brown primary spiral cords.
Dimensions: height 128.2 mm, last whorl height 83.8 mm, aperture height 71.2 mm, diameter 32.1 mm.
Remarks. — In whorl profile and type of sculpture, Nihonia maxima is most similar to the type species of
the genus, N. shimajiriensis, from the Pliocene of Okinawa. However, N. shimajiriensis is much smaller
(the incomplete holotype is 26 mm high at about 9 whorls, including 1.5 whorls of the protoconch, but the last
whorl is partly broken), lacks the styloid apical whorls with slowly increasing diameter present in N. maxima, and
has strongly angulate whorls bearing more pronounced cords. N. maxima can be easily distinguished from the two
330
A. SYSOEV
common Recent species of the genus, N. australis (Roissy, 1805) and N. mirabilis (Sowerby, 1914), by its
complex and much weaker spiral sculpture.
ETYMOLOGY. — From the Latin maximus, largest, with reference to the very large adult size.

Type Material. — Holotype and paratype MNHN.
DIAGNOSIS. — Shell biconical with cyrtoconoid spire. Protoconch of 1.5 smooth light-brown whorls,
indicating non-planktotrophic development. First teleoconch whorls angulate, with subsutural row of tubercles,
and strong, oblique, axial knobs at periphery. Last whorls with abapical portion of suture at level of undulating
peripheral keel, leaving only subsutural ramp exposed. Base of last whorl with broad Battened spiral cords separated
by narrow grooves.
Description (holotype). — Shell thin, biconical, spire cyrtoconoid. Protoconch light brown, teleoconch
white. Protoconch of 1.5 evenly convex whorls, diameter 850 pm. Teleoconch of 7.3 rapidly expanding whorls.
First 3 teleoconch whorls with broad, smooth, concave ramp with a subsutural row of pointed tubercles, and
strong peripheral keel overhanging abapical part of whorl, sculptured by broad, opisthocline axial ribs, forming
pointed knobs on periphery, and extending to abapical suture, crossed by rather indistinct, narrow, spiral cords.
After third whorl, exposed whorl height abapically of peripheral keel becomes covered by successive whorl,
gradually leaving only concave ramp exposed. On subadult and adult whorls, subsutural row of tubercles coalesced
to a wavy subsutural fold, and adapical margin of peripheral keel forming spirally striated suprasutural undulating
fold, suture impressed, undulating. Subsutural ramp broad, rather flat, with weak indistinct spiral cords, on
penultimate whorl sculptured in median area by two more distinct cords. Base of last whorl sculptured by 35 rather
strong, wide, Battened cords separated by narrow interspaces, interspaces broader on canal. Base slightly convex,
smoothly connecting to a long and straight canal. Aperture narrow, subrectangular. Inner lip covered by very thin
callus. Anal sinus deep, with rounded outline, deepest point above middle of subsutural ramp. Outer lip chipped
but, judging from growth lines, greatly projecting forward below sinus.
Dimensions: height 25.5 mm, diameter 12.2 mm, last whorl height 20.0 mm, aperture height 17.9 mm.
Remarks. — The paratype measures 36.0 x 16.0 mm for 8.5 whorls. The early whorls are decorticated, but
probably only part of the protoconch is missing. Spire whorls have the same sculpture as on the holotype In the
last two whorls there is a distinct spiral striation between abapical edge of sinus zone and peripheral keel, which is
straight, not undulating.
Clavosurcula schepmani is very similar to the type and only species of the genus, C. sibogae , from the
Mores Sea in 794 m. The latter species is, however, larger (38 mm at 8 whorls; SHUTO's [1970] measurements of
the holotype are erroneous), broader, and without peripheral knobs and subsutural tubercles, even on first
teleoconch whorls.
Etymology^ — The species is named in honor of M. M. Schepman for his pioneering work on the deep-sea
turrids of the Siboga expedition.

brownish grey periostracum, aperture of adult, live collected
specimens light orange inside. Operculum small, pyriform,
with terminal nucleus. Radular teeth large, straight, with short
rounded basal part.
DESCRIPTION (holotype). — Shell slender, fusiform, solid,
with high spire forming 41.5% of shell height. Protoconch
and early teleoconch whorls corroded. Remaining part of
teleoconch consisting of 8 convex whorls, angulate at
periphery, suture shallow, slightly channeled. Subsutural
ramp weakly convex adapically, concave abapically. Axial ribs
short, opisthocline, narrow, separated by interspaces wider
than ribs, abapically extending from angulation to suture,
evanescent on outer base; 16 ribs on penultimate whorl, 18 on
last whorl, where their vertical extension is restricted to periphery. Spiral cords rather strong, flattened, sometimes
with a narrower cord between primary ones, narrower on subsutural ramp. Interspaces between cords narrow, not
exceeding half of cord width, except on canal and adjacent portion of base, where interspaces exceed cord width.
Last whorl moderately convex, base smoothly continuous with rather long and straight canal. Aperture broad,
pyriform, evenly curved inner lip with broad callus and low pleat in adapical part of columellar edge. Outer lip
evenly curved, projecting forward below anal sinus. Sinus moderately deep, as broad as subsutural ramp, deepest
point in the middle of ramp. Shell chalky, covered with dark-brownish grey periostracum, aperture light
orange inside.

Dimensions: height 60.9 mm, last whorl height 35.6 mm, aperture height 28.7 mm, diameter 19.8 mm.
Radula of a paratype (stn CP 87, height 35.5 mm) with large, straight, narrow teeth with rounded basal part,
length 490 pm. Operculum small, pyriform, with slightly curved axis and terminal nucleus.
Remarks. — The paratypes are 35.5 to 70.5 mm high, with some variation in proportions of the last whorl
(e.g. Figs 41-42). Younger specimens (Fig. 43) have a relatively broader body whorl with axial ribs proportionally
higher, extending to shell base. In such small specimens the aperture is greyish-white inside. The importance of
columellar pleat may vary slightly, it is present in all but one specimen. Axial ribs on last whorl number 17-19.
Bor sonia jay a is very similar to B. epigona Martens, 1901 from west of Sumatra, 646-676 m, but the latter is
much smaller (up to 28 mm high), with distinctly angulate shell base, straight axial ribs, very prominent
columellar pleat, and, judging from the original illustration, without spiral sculpture in the subsutural ramp.
B-jaya also shows some similarity to the type-species of Buridrillia Olsson, 1942, Clathrodrillia (Buridrillia)
panarica Olsson, 1942 from the Pliocene of Central America. However, it has been recently shown (Emerson &
McLean, 1992) that Buridrillia has radular teeth of modified wishbone type and therefore belongs to the subfamily
Crassispirinae.
Etymology. — From the Indonesian jaya, meaning large, beautiful.
Genus HETEROTURRIS Powell, 1967
Type Species: Heteroturris sola Powell, 1967.
Remarks. Heteroturris was originally described in the subfamily Turrinae because POWELL (1967)
considered it closely allied to Lophiotoma Casey, 1904. Powell also noticed that the sculpture of the subsutural
ramp resembles that ot Microdrillia Casey, 1903, which he classified in subfamily Clavinae. Taylor et al. (1993)
have included Microdrillia in the “tomopleurid” group of genera of the subfamily Clathurellinae (Conidae). The
style and position of anal sinus in Heteroturris is rather different from the character states of Turrinae, and the
radular morphology of H. gemmuloides confirms the classification of Heteroturris in Clathurellinae.

long canal. Whorls with rather prominent bicarinate subsutural fold, concave subsutural ramp, and prominent,
tuberculate, peripheral keel. Subsutural ramp bearing numerous, regular, curved folds formed by thickened scars of
anal sinus. Abapically of keel, spiral cords strong and widely spaced, sometimes with a thinner cord in interspaces
two on exposed part of spire whorls, over 20 on base and canal of last whorl. Anal sinus deep, U-shaped, with
parallel sides. Shell chalky white under rather thick light-brown periostracum. Operculum small, vestigial, with
large central nucleus. Radula long, with more than 50 transverse rows. Radular teeth small, inflated at the base

whorls. Subsutural ramp wide, concave with rather massive, broad, flat-topped, bicarinate subsutural fold and
2 weak spiral threads in the middle, ramp bearing numerous, regular, curved folds formed by thickened scars of
anal sinus. On last whorl, cords of subsutural fold becoming strongly and irregularly granulate, and appearing like
a spirally twisted rope, due to intersection with growth lines. Peripheral keel moderately prominent, bearing
numerous rounded tubercles truncated adapically at edge of ramp, 24 tubercles on penultimate whorl, 27 on last
whorl. Spiral sculpture consisting of one abapical cord bordering suture, and one additional strong cord (missing on
apical whorls) below peripheral keel. On last whorl, periphery with 4 widely interspaced strong cords, additional
thinner cords appearing in between. Base and canal covered by ca. 26 cords, sometimes with thinner cord in
interspaces; adapical basal cords of almost same strength as those at periphery, but prominence of cords gradually
decreases towards tip of canal, where cords are obsolete. Axial sculpture consisting of strong incremental lines,
intersection with spiral cords granular. Aperture rather narrow, ovate, gradually continued by long and straight
canal. Inner lip covered by thick callus, parietal wall weakly and evenly curved. Anal sinus deep, U-shaped, with
parallel sides, occupying entire width between subsutural fold and peripheral keel. Colour chalky white under thick
light-brown periostracum.
Dimensions: height 40.5 mm, last whorl height 24.4 mm, aperture height 21.1 mm, diameter 1 1.8 mm.
Operculum (of paratype) small, 1.05 x 0.6 mm, vestigial, very thin, with large central nucleus. Radula long,
narrow, with over 50 transverse rows. Radular teeth rather small, mean length 270 pm (in specimen 38.5 mm
high), short, base strongly inflated, with proximal opening.
Remarks. — Paratypes are smaller than holotype: 38.5 x 11.3 mm and 33.0 x 9.7 mm. Specimens from
Indonesia are very similar to the holotype, except for minor variation in the strength and number of peripheral
tubercles, and width of subsutural fold, which may be slightly concave between two marginal cords. The specimen
from the Philippines (Fig. 23) has a stronger subsutural fold, and a slightly narrower subsutural ramp, especially
on last whorl, with only one thin thread in its middle. Heteroturris gemmuloides is very similar to H. sola , but
differs in attaining twice the size, with a broad, bicarinate subsutural fold, and a nodulose peripheral keel. The
shape of radular teeth is very similar to that of Typhlomangelia polythele Barnard, 1963 and T. adenica Sysoev,
1996 (Barnard, 1963, fig. 3f; Sysoev, 1996, fig. 4).
ETYMOLOGY. — Named gemmuloides because of its superficial resemblance to species of Gemmula.
Distribution. — Tanimbar Islands, Indonesia, and southwest of Luzon Island, Philippines, taken alive at
330-399 m.

discontinuity. Teleoconch consisting of 6.25 whorls. Spiral sculpture on spire whorls consisting of a thick,
overhanging subsutural fold with flattened and steeply descending surface, a strong, smooth peripheral keel, and
another cord bordering abapical suture (on last 2 spire whorls only). Axial sculpture consisting of strong
incremental folds that do not extend over main spiral cords. Subsutural fold consisting of a strong, smooth spiral
cord abapically and a much weaker crenulated adapical cord, separated by area covered by oblique incremental
wrinkles. Subsutural ramp rather narrow, concave, covered by distinct, crisp, arcuate incremental folds formed by
scars of anal sinus, and on last 3 whorls bearing a narrow cord running in the middle of ramp and forming tubercles
at intersection with axial folds. Periphery and base of last whorl with 4 strong cords with wide interspaces,
followed by 13 gradually weakening cords on canal. Canal long and straight. Aperture rather narrow, pyriform,
with a strong lira inside. Inner lip covered by thick callus, parietal side evenly curved. Outer lip chipped, but
growth lines indicating broad and shallow anal sinus. Colour yellowish-white, with a very thin periostracum.
Dimensions: height 9.5 mm, last whorl height 6.0 mm, aperture height 4.8 mm, diameter 3.4 mm.
Remarks. — Heteroturris serta differs from H. sola in having a solid and broad subsutural fold, stronger spiral
sculpture, and a protoconch with fewer whorls. It also differs from H. gemmuloides in its stronger spiral sculpture
and smooth peripheral keel. The holotype of H. serta may not be fully adult, but it is well preserved and the
species should be easily recognizable, either as a juvenile with protoconch or as a mature specimen with adult
sculpture.
Etymology. — From the Latin sertus, plaited, with reference to the very regular incremental sculpture.

Protoconch multispiral, consisting of ca. 3 diagonally cancellated whorls. Teleoconch whorls with deep, slightly
channeled suture, and very broad, slightly concave subsutural ramp, occupying most of height on spire whorls.
Strong spiral keel adjacent to abapical suture in early whorls and well below periphery in penultimate whorl. Last
whorl with 10 fine spiral cords and numerous closely set sigmoid incremental lines in subsutural ramp, and several
strong and narrow cords below keel, thin secondary and tertiary cords in interspaces. Siphonal canal short and
curved. Anal sinus moderately deep, asymmetrical, with deepest point in lower half of ramp. Colour of protoconch

slightly concave subsutural ramp. Primary sculpture consisting of spiral cords, only the strongest adapical one
exposed on early whorls, forming a suprasutural keel; penultimate whorl with one additional strong cord exposed
below keel; last whorl with 8 strong, widely spaced primary cords exposed on base below peripheral keel,
1-3 thinner secondary cords in interspaces; 9 weaker cords on canal. Subsutural ramp smooth on early whorls, on
later whorls bearing narrow spiral cords, 8 on penultimate, 10 on last whorls, the second from adapical margin and
the most abapical ones strongest. Axial sculpture of numerous, narrow sigmoid folds formed by thickened
incremental lines. Axial folds and spiral cords forming reticulate pattern in ramp, small nodules at points of
intersection. Canal rather short and curved. Aperture oval, columella thick, forming a distinct angle with parietal
part of inner lip. Anal sinus asymmetrical, moderately deep, steeply descending adapically, deepest point rounded in
abapical half of ramp. Protoconch light brown, teleoconch off-white.
Dimensions: height 1 1.8 mm, diameter 4.8 mm, body whorl height 7.0 mm, aperture height 5.2 mm.
Remarks. — In the paratypes (dimensions 12.8 x 5.1 mm, 9.3 x 3.7 mm, and 7.7 x 3.5 mm), the strength
and relative position of the main spiral keel vary a little, as do also the concavity of the subsutural ramp and the
number of cords on the ramp and in interspaces of primary spirals. One paratype has a protoconch of about
3 whorls with etched surface, but even in that specimen the earliest part is dissolved.
Cryptodaphne rugosa resembles C. affinis (Schepman, 1913), but can be easily distinguished by its
proportionally larger body whorl, differently shaped anal sinus, and details of sculpture. In fact, it is much more
similar to the fossil type-species than to any of the Recent species assigned to the genus (Powell, 1966;
Shuto, 1971). The New Zealand type species C. pseudodrillia was originally recorded from the Lower Miocene
(Powell, 1942) and later (Powell, 1966) the Upper Oligoccne, but Beu & Maxwell (1990) list it in the Early
Miocene faunal assemblage. C. rugosa is almost twice the size of the holotype of C. pseudodrillia and differs
mainly in the shape of the anal sinus, in C. pseudodrillia “descending almost vertically and then abruptly produced
forward” (Powell, 1942: 165), as well in the twisted canal, absence of “close-spaced spiral threads” covering the
entire shell surface, and presence of minute granulation.
The diagonally cancellate protoconch sculpture clearly indicates a position in Raphitominae, however C. rugosa
possesses features more frequently encountered in Clathurellinae, such as the closely spaced axial folds, formed by
thickened growth lines, well developed over the entire subsutural ramp, and the presence of minute granulation on
the shell surface.
Etymology. — Rugosus, Latin adjective meaning rough, with reference to granular microsculpture.

angulate below periphery, angulation obsolete on last adult whorl. Subsutural ramp broad, moderately to weakly
concave, without axial sculpture and with fainter spiral cords, sometimes with thickened scars of anal sinus
adapically. Axial ribs oblique, rather short, reaching abapical suture, only occupying periphery on adult whorls,
obsolete on last whorl of large adults. Spiral cords flat, separated by narrow interspaces and, sometimes, additional

narrower cords. Anal sinus broad, moderately deep, somewhat angulate. Colour reddish-violet, with lighter
subsutural band, aperture brown inside. Radular teeth straight, narrow, barbed, with narrow trilobate basal part.
Description (holotype). — Shell fusiform, thin but solid, with tall spire comprising 41.5% of shell height.
Protoconch and outer layers of apical teleoconch whorls dissolved, only traces of brown protoconch columella
remaining. Teleoconch consisting of 10 whorls, suture shallow, slightly channeled. Apical whorls angulate at
periphery, angulation weaker and situated a little below periphery in subaduit whorls, last whorl rather evenly
rounded. Whorl profile concave above angulation, slightly convex below it. Axial sculpture consisting of ribs that
extend abapically from whorl angulation to outer base, oblique, weakening abapically, 14 on penultimate whorl,
obsolete on last whorl. Spiral sculpture consisting of narrow grooves delimiting low, flat spiral bands, grooves
weaker on subsutural ramp, deeper below periphery. Base evenly convex, smoothly continuous with rather short,
straight, moderately broad canal. Aperture broad, oval, parietal side weakly concave, separated by obtuse angle from
straight columella. Inner lip a thin, broad callus, outer lip evenly curved. Anal sinus moderately deep, broad,
slightly angulate, deepest point just below middle of subsutural ramp. Colour dull reddish-violet, with a lighter
band subsuturally in part of ramp, aperture and columella orange brown. Periostracum very thin, transparent.
Dimensions: height 46.3 mm, last whorl height 27.1 mm, aperture height 21.2 mm. diameter 16.0 mm.
Last 1-1.5 protoconch whorls preserved on 2 paratypes, brown, with sculpture of spiral cords interrupted by
close set, curved axial riblets. Radular teeth of 34.2 mm high paratype straight, narrow, barbed, with narrow
trilobate basal part, mean length 170 pm (Fig. 3). No operculum.
Remarks. — The paratypes are smaller than the holotype (largest 45.5 x 16.3 mm). In smaller specimens, the
axial ribs number 14 or 15 on the last whorl and do not extend onto shell base. The adapical part of the subsutural
ramp may bear numerous, regular, thickened scars of the anal sinus.
Gymnobela ioessa resembles G. muricata , occurring sympatrically, but differs in having a more slender,
reddish-violet shell, higher axial ribs reaching suture abapically, and smaller radular teeth with narrow, trilobate
basal part. G. ioessa also attains a smaller size.
G. ioessa and G. muricata form a distinct group within the genus, which combines characters of two different
subfamilies of Conidae. The general shell outline and colouration, and the character of anal sinus are similar to
those of Clathurellinae (e.g., Borsonia and Typhlosyrinx Thiele, 1925), whereas the protoconch sculpture and the
structure of radular teeth indicate a position in the Raphitominae. These species, however, can be placed in
Gymnobela taken in a broad sense, as is frequently adopted in the current literature.
Etymology. — From the Greek ioeis (feminine ioessa ), meaning violet or dark brown, based on the ground
colour of the shell.

Description (holotype). — Shell broadly fusiform, thin but solid, with tall spire comprising 39% of total
shell height. Protoconch and apical whorls dissolved. Teleoconch consisting of 10 whorls, suture shallow. Earliest
teleoconch whorls angulate just below middle of whorl, angulation weaker on subsequent whorls, last whorl
almost evenly rounded. Whorl profile weakly concave above angulation, almost flat below. Axial ribs very short,
oblique, extending abapically from whorl angulation on earliest teleoconch whorls, forming rounded knobs just
below periphery on subadult whorls (18 ribs on penultimate whorl), obsolete on last adult whorl. Spiral sculpture
consisting of narrow, shallow, unevenly spaced grooves separating low, flat cords. Cords weaker but more regular
on subsutural ramp, stronger but uneven below whorl angulation. Last whorl rather inflated, with evenly convex
base, clearly separated from short, very broad, slightly twisted siphonal canal. Aperture broad, oval. Inner lip
covered by thin, broad, longitudinally wrinkled callus, concave parietal and columellar sides forming obtuse angle.
Outer lip evenly convex. Anal sinus moderately deep, broad, slightly angulate, deepest point in abapical part of
subsutural ramp. Colour chalky light yellowish brown.

Radular teeth of 33.3 mm high paratype weakly barbed with strong basal spur and bifurcate basal part, mean
length 275 pm (Fig. 4). No operculum.
Remarks. — The paratypes are smaller than the holotype (the largest is 52.1 x 20.6 mm). Small specimens
are dull greyish-white, with a very thin transparent periostracum, and proportionally longer and narrower canal. The
protoconch is dissolved in all specimens, but there are traces of a brown layer, suggesting that the protoconch was
of the planktotrophic type.
For differences with G. ioessa, see that species.
ETYMOLOGY. — From the Latin muricatus (adj.), meaning pointed or spiny like a murex, with reference to the
high spire and short, knob-like axial ribs.

protoconch with traces of brown, teleoconch glassy light-brown.
Dimensions: shell height 26.6 mm, diameter 8.1 mm, body whorl height 15.8 mm, aperture height 12.8 mm.
Remarks. — The paratype measures 22.0 x 7.1 mm and has 7.5 teleoconch whorls (protoconch corroded,
surface etched). Whorl angulation is approximately at periphery, which also results in a slightly broader subsutural
ramp. It also differs slightly from the holotype in the ribs being slightly more axially elongated.

Gymnobela micraulax can be easily distinguished from other Indo-Pacific species of Gymnobela by its high
spire and sculpture of narrow grooves.
ETYMOLOGY. — Micraulax, Greek (adj.) meaning with small furrows, with reference to the spiral sculpture.

(holotype), 1 dd (paratype).
Type Material. — Holotype and paratype MNHN.
Diagnosis. — Shell thin, up to 36 mm high, with high spire occupying 45% of shell height. Proto¬
conch multispiral, with diagonally cancellated sculpture. First teleoconch whorls with angular periphery,
weakly concave anal sinus occupying ca. 60% of subsural ramp, periphery with very short oblique axial ribs,
last whorls almost evenly convex. Spiral sculpture of fine spiral cords and strongly sigmoid incremental
lines, intersection irregularly reticulate. Colour white, adapical half of last whorls with very pale yellowish-white
band.
Description (holotype). — Shell consisting of 1+ protoconch and 9.5 teleoconch whorls, slender, thin but
rather solid, high, fusiform, tall spire occupying 45% of shell height, suture rather deep, slightly channeled. Tip of
protoconch dissolved, remaining whorl surface etched but remnants of sculpture typical of multispiral larval shell
with diagonally cancellated sculpture, indicating planktotrophic development. First 6 teleoconch whorls distinctly
shouldered, weakly concave sinus zone occupying about 60% of broad subsutural ramp, whorl profile almost flat
above and below strong peripheral angulation. Subsequent whorls almost evenly convex, subsutural ramp flat with
poorly defined abapical border. Axial sculpture consisting of strongly sigmoid incremental lines, forming raised
opisthocyrt riblets in sinus zone, and strongly prosocline threads below sinus; very short, broad, opisthocline ribs
on periphery of spire whorls, ca. 15 per whorl, vanishing on 6th and subsequent whorls. Spiral sculpture
consisting of cords, weakly defined and widely spaced in sinus zone, sharply defined, thin, rounded and closely
spaced on rest of the whorl, a few stronger below periphery. Intersection of incremental lines and spiral cords rather
regularly reticulate on spire whorls, more irregularly so on last whorl, due to unevenness of lines and cords.
Aperture rather broad, oval, widely open siphonal canal not distinctly set off. Inner lip with thin, polished callus
extending over convex parietal and concave columellar areas. Outer lip chipped, anal sinus (from shape of growth)
rather deep, its deepest point in middle of subsutural ramp. Colour chalky white, adapical half of last whorls with
very pale yellowish-white band.
Dimensions: height 36.2 mm, diameter 12.8 mm, last whorl height 21.3 mm, aperture height 16.7 mm.
Radular teeth (Fig. 6) straight, unbarbed, basal part subquadrate in frontal view, length 250 pm.
Remarks. — The paratype (21.6 x 8.5 mm at 2+ protoconch and 7.5 teleoconch whorls) is a damaged and
slightly eroded shell. Whorl profile and sculpture correspond to the characters of holotype at comparable size, but
whorl angulation is more pronounced than on corresponding (7th) whorl of the holotype; also, spiral cords and
growth lines are slightly coarser.
Gymnobela baruna is rather different from most other representatives of the genus. The general shell outline,
the absence of prominent axial sculpture and fine spiral cords are more characteristic of Xanthodaphne . However,
the high spire and clearly defined broad subsutural ramp, delimited by the whorl angulation in early whorls, are
features that do not fit that genus. G. baruna is most similar to the species illustrated by Matsumoto (1979,
pi. 17. fig. 3) as Daphnella proximo Kuroda. The latter, however, is a manuscript name and a nomen nudum
[ICZN Art. 13a(i)].
ETYMOLOGY. — From the name of the Indonesian research vessel "Baruna Jaya 1" which collected the
material. Baruna is used as a noun in apposition.

Type Material. — Holotype MNHN.
Diagnosis. — Shell small, about 7 mm high, short, wide, solid, with few rapidly expanding whorls.
Protoconch multispiral with diagonally cancellated sculpture. Teleoconch whorls angulate. Last whorl almost as
high as wide, completely covered by sculpture of low, wide cords, intersecting numerous, stronger but narrower
axial ribs, intersection forming axially elongated nodules. Aperture broad. Canal very short and poorly
differentiated from aperture. Anal sinus broad and shallow.
Description. — Shell small, solid, broadly biconical, with low spire and very large, inflated last whorl,
occupying 74% of total shell height. Protoconch consisting of 2+ convex whorls, protoconch I and probably about
0.5 whorl of protoconch II missing, sculpture of opisthocyrt, opisthocline axial riblets, forming diagonal
cancellation with oblique threads in abapical two-thirds. Axial riblets nearly orthocline near clearly defined
protoconch/teleoconch discontinuity. Teleoconch consisting of 3.8 rapidly expanding whorls, with sharp
angulation above periphery, subsutural ramp weakly concave. On first teleoconch whorl, two spiral cords and
a third, poorly defined one on shoulder, intersecting thinner axial riblets, intersection forming axially elongate
nodules. On 2nd and third whorls, an additional spiral cord exposed above suture, shoulder cord more distinct,
intersecting axial riblets of similar strength, intersection forming rounded beads. On last whorl, 19 spiral cords and
35 ribs; subsutural cord indistinct on broad subsutural fold, peripheral cords broad, low, separated by narrow
groove, cords on base and canal higher and separated by interspaces occupying equal width; axial ribs sharp,
stronger than cords, forming raised, prosocline, sigmoid wrinkles in subsutural zone, rather orthocline and
extending over whole whorl height below angulation, forming checkerboard pattern with spiral grooves. Aperture
broad, parietal wall convex with rather thin callus, columella almost straight with thicker callus. Canal short and
broad. Outer lip broken, but growth lines indicating very shallow sinus, with deepest point at whorl angulation.
Protoconch brown, teleoconch beige-white.
Dimensions: height 6.9 mm, diameter 4.8 mm, last whorl height 5.1 mm, aperture height 3.9 mm.
Remarks. Mioawateria asarotum is similar to the type species, M. personata, but differs in having much
lower spire and inflated body whorl. In shell outline, it is similar to M. rhomboidea (Thiele, 1925) from West
Africa, but differs in its smaller shell with curved axial ribs and very wide spiral cords. M. extensaeformis
(Schepman, 1913), which is rather common in the Indo-Pacific bathyal, has a narrower shell and much weaker
spiral sculpture.
ETYMOLOGY. Latin asarotum (noun in apposition), a floor laid in mosaic, with reference to the elongated
squares formed by intersection of axial and spiral sculpture.

Type Material. — Holotype MNHN.
Diagnosis. — Shell of medium size, 21 mm high, thin, porcellaneous, with high pagodiform spire.
Teleoconch whorls very convex, with keeled periphery. Axial ribs numerous, very short, restricted to whorl
periphery, forming narrow oblique knobs on keel. Spiral sculpture of strong cords below periphery, interspaces
rather wide. Last whorl attenuated towards moderately long, straight canal. Subsutural ramp broad, almost devoid
of sculpture, sinus rounded, deepest point in middle of ramp. Radular teeth short, straight, with bilobate basal part.
Description (holotype). — Shell thin, porcellaneous, broadly fusiform, consisting of 8.5+ very convex
teleoconch whorls (protoconch and apical teleoconch whorls dissolved) with high pagodiform spire occupying 42%
of total shell height. Suture impressed, periphery angulate, subsutural ramp broad, convex, whorl profile concave
abapically of slightly overhanging peripheral keel, base regularly convex. Outer shell layer etched on spire whorls,
details of sculpture preserved on last two whorls only. Axial sculpture consisting of numerous (28 on penultimate
and last whorls), short, opisthocline riblets, forming oblique nodules on peripheral keel and extending to abapical
concavity only; incremental lines very distinct in ramp, occasionally thickened as opisthocyrt wrinkles. Spiral
sculpture in subsutural ramp consisting of 6-8 poorly defined cords, on and below peripheral keel consisting of
strong, sharply defined cords, interspaces broader than cords, 2 stronger cords just above suture in exposed part of
spire whorls. Base convex, canal distinctly set off, long, straight, narrow. Aperture ovate, inner lip a thin glaze
over weakly convex parietal area and almost straight columella. Outer lip chipped, based from incremental lines
anal sinus occupies whole ramp, rounded, deepest point on abapical side of middle part of ramp. Colour por¬
cellaneous white, etched shell surface and interspaces between cords opaque, chalky white, ramp and cords vitreous.
Dimensions: height 21.3 mm, diameter 10.5 mm, last whorl height 13.4 mm, aperture height 11.1 mm.
Radular teeth 250 |4m long, straight, short, with a bilobed and turned out basal part (Fig. 7).
REMARKS. — Until now the genus Clinura was known only from Oligocene to Pliocene deposits in Europe,
Indonesia and New Zealand (POWELL, 1966), and C. vitrea is the first Recent record. Regrettably, however, the
protoconch of the new species is unknown, and this makes the generic placement only provisional. It is similar to
the type species from the Pliocene of Italy. Characters shared by fossil species of Clinura and C. vitrea are the
fusiform-biconic shell profile with a pagodiform spire, narrow canal, crenulate peripheral keel, and strong spiral
sculpture below whorl periphery. In C. calliope the anal sinus is rather shallow and has the apex in the upper part
of subsutural ramp but the form and position of anal sinus vary rather greatly within the genus (see BEETS, 1942)
and in some species are similar to those of C. vitrea.
ETYMOLOGY. — Latin vitreus (adjective), like glass, with reference to both the fragility of the shell and the
semi-transparent appearance.

A. SYSOEV
Type Material. — Holotype MNHN.
DIAGNOSIS. — Shell large for genus, 21 mm high, very thin and fragile, slender, with high spire. Protoconch
multispiral with oblique axial ribs. Teleoconch whorls weakly angulate at shoulder, narrow, weakly concave
subsutural ramp with regular fold-like scars of anal sinus. Sculpture finely reticulate, of numerous thin axial
riblets and thin strong spiral cords, interspaces spirally elongate. Canal moderately long, slightly twisted and
obliquely truncated. Anal sinus deep, deepest point in adapical part of ramp. Colour white.
DESCRIPTION. — Shell very thin and fragile, slender, fusiform, with high spire comprising 37% of total shell
height. Protoconch I and tip of multispiral protoconch II dissolved, only last whorl remaining, convex, sculptured
by strong, coarse, prosocline axial ribs; protoconch / teleoconch discontinuity sharp. Teleoconch consisting of
7.0 whorls, suture tightly impressed, whorls weakly angulate at shoulder, evenly convex below shoulder.
Subsutural ramp narrow, weakly concave, without spiral sculpture, with numerous regular, raised, opisthocyrt
wrinkles corresponding to scars of anal sinus. Sides finely reticulately sculptured by numerous (42 on last whorl),
prosocyrt, sharply defined, narrow axial riblets overriden by almost equally strong but narrower spiral cords,
interspaces spirally very elongate, intersection of cords and riblets spirally elongate; 3 spiral cords on first
teleoconch whorl, additional cords added at shoulder and between cords, reaching 20 on penultimate whorl, 35 on
periphery and base of last whorl, plus 13, slightly stronger, on canal. Base evenly connected to moderately long,
twisted, and obliquely truncated canal. Aperture pyriform. Inner lip strongly concave on abapical part of parietal
side, covered by thin, translucent, axially wrinkled callus. Outer lip damaged, anal sinus (based on incremental
scars) deep, deepest point in adapical part of ramp. Colour of protoconch deep brown, of teleoconch semi¬
transparent white with thin, tightly adhering beige periostracum.
Dimensions: height 21.1 mm, diameter 7.7 mm, last whorl height 13.2 mm, aperture height 10.2 mm.
Remarks. — Veprecula bandensis can be included in Veprecula on the basis of shell outline, reticulate
sculpture, and characteristic sculpture of protoconch. It is most similar to the type species, V. sykesi , but differs in
having a much larger shell with lower spire, fainter sculpture, twisted canal, and poorly prominent intersection of
axial and spiral sculpture. Other known species of the genus have a much stronger sculpture, consisting of widely
spaced ribs and cords.
The new species is also similar to Daphnella thia Melvill & Standen, 1903 (the original figure of that species
is rather inadequate, but it was recently illustrated by BOSCH et al., 1995: 167) in shell outline and sculpture, but
differs in having more curved ribs, a well differentiated subsutural ramp, and different protoconch sculpture.
Etymology. — Bandensis , an adjective based on the stem Banda (Sea), the type locality.

opisthocyrt folds formed by thickened growth lines, becoming obsolete on last whorls. Canal rather long,
columella slightly twisted.
DESCRIPTION (holotype). — Shell buccinoid, very thin, fragile, consisting of 2.1+ protoconch and
6 teleoconch whorls. Tip of protoconch broken, probably consisting of protoconch I and less than 0.5 whorl of
protoconch 11. Remaining whorls forming a rather low spire, diameter 1 .05 mm, sculptured over abapical two-
thirds by oblique reticulation, and opisthocyrt riblets on adapical third. Protoconch/teleoconch boundary sharp.
Teleoconch whorls very convex, with rather deep, impressed suture, slightly concave subsutural ramp defined only
on first 4 whorls, last two whorls very regularly convex. Sculpture fine and delicate, consisting of sigmoid
incremental lines, obsolete in last 2 whorls, strong in first 4 whorls, forming raised opisthocyrt wrinkles in
subsutural zone, and low, indistinct, prosocyrt lines below shoulder; numerous, fine, flattened spiral cords,
interspaces narrow, indistinct on first two whorls, stronger on subsequent whorls, also present in subsutural zone.
Last adult whorl strongly convex, with weak incremental lines and thin, but strong spiral cords, 4 or 5 per mm on
periphery, a little more crowded on base, more spaced on canal. Canal rather long, broad, straight. Aperture broad,
columella slightly twisted, without inner lip callus. Based on growth lines, anal sinus broad, very shallow. Colour
light-brown, protoconch brown.
Dimensions: height 31.7 mm, diameter 13.8 mm, last whorl height 22.3 mm, aperture height 17.1 mm.
Remarks. — The paratype (30.4 x 12.4 mm at 6 teleoconch whorls) has a less inflated last whorl:
diameter/height 0.41 vs. 0.435 in the holotype. Such a difference could possibly represent sexual dimorphism.
Growth lines on the last whorl are more distinctly sigmoid than in the holotype, due to more prosocyrt profile on
periphery. Radular teeth 280 pm, straight, with short but strongly expanded basal part (Fig. 8).
Xanthodaphne cladara is similar to X. subrosea (Barnard, 1963) from off Cape Point, South Africa, 2524-
2780 m, but differs in having a more slender shell, with more slowly expanding whorls, a smaller protoconch
(diameter 1.45 mm in subrosea ), and fainter spiral sculpture.
ETYMOLOGY. — From the Greek kladaros (adj.; feminine kladara), easily broken, with reference to the fragility
of the shell.

fainter spiral threads in axial interspaces. Protoconch/teleoconch boundary sharp. Teleoconch whorls evenly
convex, suture impressed, rather deep. Spiral sculpture consisting of fine, flattened cords, occasionally in last
2 whorls with thinner additional cord in interspaces, interspaces equal to or narrower than cord width, 17 on
penultimate whorl, about 75 on last whorl. Axial sculpture consisting of numerous, evenly spaced, orthocline,
thickened incremental lines, interspaces narrow. On first half teleoconch whorl, spiral cords stronger than
incremental ribs; on subsequent 2 whorls, cords and ribs of equal strength, cords a little rugose at intersection with
ribs, producing a finely reticulate sculpture; on last 2 whorls, spiral cords stronger than incremental riblets. Base
regularly convex, connected rather abruptly to rather short, straight canal. Aperture broad, columellar and parietal
areas of inner lip forming an obtuse angle, callus very narrow, outer lip partly broken, but apparently regularly
convex. No distinct anal sinus. Colour light-brown, protoconch brown. No operculum. No radula.
Dimensions: height 16.9 mm, diameter 9.4 mm, last whorl height 13.2 mm, aperture height 10.4 mm.
REMARKS. — Lusitanops dictyota is similar to L. cingulata Bouchet & Waren, 1980 from the upper abyssal of
the North-Eastern Atlantic, but differs in having a much larger shell with fainter and closely set spiral cords. This
is the first record of Lusitanops outside the North-Eastern Atlantic.
The specimen from New Caledonia is very similar to the holotype, except for being much smaller (8.6 x
5.2 mm at 3+ adult whorls), with slightly broader last whorl. Its protoconch consists of 2.5 remaining whorls,
upper ca. 1.25 whorls missing.
Etymology. — From the Greek dictyotos (adj.), reticulate, with reference to the sculpture of the teleoconch.
Distribution. — Tanimbar Islands, Indonesia, and southward of New Caledonia, taken alive at 620-1530 m.
CONOEDEA incertae sedis
Genus THELECYTHARELLA Shuto, 1969
Type Species: Agladrillia oyamai Shuto, 1965.
Among existing genera of Conoidea, the new species described below conforms rather well with
Metaclathurella Shuto, 1983 [type species: Austropusilla (Metaclathurella) crokerensis Shuto, 1983), originally
classified by Shuto as a subgenus of Austropusilla Laseron, 1954. KlLBURN (1995) has synonymized
Metaclathurella and Lioglyphostomella Shuto, 1970 with Thelycytharella [sic!], and stated that Austropusilla is
not related. This synonymization seems reasonable, with Metaclathurella only characterized by a complete absence
of axial sculpture. Within this complex, T. vitrea (Reeve, 1845) and T. kecil sp. nov., form a distinct group
characterized by a very small (5.5 mm high) pupoid shell without axial sculpture, and further research may prove
that they belong to a separate genus.
The taxonomic position of Thelecytharella is unclear. It was originally placed in the subfamily Mangeliinae, an
opinion followed by KlLBURN (1995), without an indication of reasons for such placement. However,
conchological characters alone are insufficient to allocate it to a subfamily, and even to a family. Examination of
anatomy is badly needed, but the present material is represented by a single empty shell.

DIAGNOSIS. — Shell small, 5.5 mm, but solid, subcylindrical, few-whorled, white. Protoconch multispiral,
smooth. Teleoconch whorls very weakly but evenly convex, covered by strong spiral cords, 5 on first whorl, 22 on
last whorl. Aperture narrow, canal very short. Anal sinus moderately deep, rounded, directed somewhat adapically.
DESCRIPTION (holotype). — Shell very solid, subcylindrical, consisting of 2+ protoconch and 3.1 teleoconch
whorls. Tip of protoconch dissolved, plugged by secondary callus, remaining whorls smooth, polished, with
strongly opisthocyrt incremental lines and strong basal keel partly covered by successive whorl; protoconch
diameter 850 |um, i.e. half diameter of first teleoconch whorl. Protoconch/teleoconch boundary sharp. Teleoconch
whorls rapidly growing but slowly expanding, weakly and evenly convex, suture shallow. Sculpture primarily
spiral, consisting of strong rounded cords, 5, 7 and 22 on first to third whorls respectively, two adapical cords more
widely spaced at level of sinus. Very fine spiral microsculpture in interspaces between cords. No axial sculpture
other than fine, sigmoid incremental lines. Aperture ovate, narrow, siphonal canal very short, indistinctly set off.
Inner lip evenly curved, covered by thick callus with free edge. Outer lip with thin edge but strengthened behind by
low varix, deep stromboid notch at base of siphonal canal. Anal sinus moderately deep, semi-enclosed, directed
slightly adapically. Colour white.
Dimensions: height 5.5 mm, diameter 1.6 mm, last whorl height 3.4 mm, aperture height 2.4 mm.
REMARKS. — In shell shape, the new species is very similar to T. vitrea from the Philippines (Iectotype
figured by KlLBURN, 1995, fig. 12), but clearly differs in having strong spiral sculpture.
Etymology. — From the Indonesian kecil (adj.), small, with reference to the small adult size. It is used here
as an invariable noun in apposition.
Genus ALICEIA Dautzenberg & Fischer, 1 897
TYPE Species: Aliceia aenigmatica Dautzenberg & Fischer, 1897.
Remarks. — The taxonomic position of Aliceia is rather enigmatic, and the species described below offers no
help. The anal sinus of the type species is shallow, whereas in A. simplicissima (Thiele, 1925) it is deep, rather
narrow, and distinctly peripheral. Such style of anal sinus suggests that the genus may belong to the family
Turridae, subfamily Turrinae, or to the bathytomine group of Clathurellinae (Conidae). At the same time, the
protoconch is more similar to some genera of the subfamily Raphitominae (Conidae), e.g., Pleurotomoides Bronn,
1831 and Famelica Bouchet & Waren, 1980. In shell outline, sinus character, and the absence of sculpture,
A. simplicissima resembles the turrine genus Lucerapex Iredale, 1936. However, Lucerapex has a paucispiral
globular smooth protoconch and nodules or scales on the peripheral keel.
Aliceia presently includes three species: the North Atlantic A. aenigmatica , the Indo-West Pacific
A. simplicissima , and the Hawaiian species figured by Kay (1979: 364, fig. 115 N) as “ Thatcheriasyrinx sp." and
suggested by Bouchet & Waren (1980) to be also a member of Aliceia. This genus thus appears to have a
world-wide distribution. Whereas A. aenigmatica and “ Thatcheriasyrinx sp.” are very similar to each other in shell
outline, and possess a broad and shallow anal sinus, a false umbilicus, and semi-tubular processes on the
periphery, A. simplicissima differs in having a slender shell lacking sculpture, with a rather deep and narrow anal
sinus. Nevertheless, the thin small shell without spiral cords or axial ribs, the more or less peripheral position of
the sinus, and the peculiar protoconch with axial pillars below peripheral keel are characters shared by all three
species, and it seems reasonable to include the species of Thiele in Aliceia, at least until more material, with soft
parts, comes to hand.

Type Material. — The shell collected by the "Valdivia" at the station 245 is here designated as the lectotype.
The other shell is a paralectotype. Both are deposited at the Zoologisches Museum, Berlin, no registration number.
DESCRIPTION (Karubar specimen). — Shell slender, thin, semi-transparent, consisting of 3+ protoconch and
4.7 teleoconch whorls, suture impressed, deep. Tip of protoconch (probably protoconch I and less than 0.5 whorl
of protoconch II) broken, remaining whorls smooth above periphery, sculptured by short straight axial ribs below
periphery, indistinct near protoconch/teleoconch boundary. Teleoconch whorls obtusely angulate at periphery,
angulation stronger towards adult whorls, periphery occupied by anal sinus forming a band with sharply defined
edges. Incremental lines thin, indistinct, strongly prosocyrt above and below periphery, strongly opisthocyrt in
sinus zone. No spiral sculpture. Aperture broadly subtriangular, canal moderately long and straight. Shell colour
translucent white, with one light-brown spiral band at base of exposed whorl height, encircling base of last whorl,
and a second narrower band encircling base of canal.
Remarks. — None of the shells of the Zoologisches Museum, Berlin, corresponds to measurements given by
THIELE (5x1.8 mm), but the shell from Zanzibar (apparently figured by THIELE) is better preserved and is for this
reason designated as lectotype. It has 3.5 teleoconch and 3+ protoconch whorls.

APPENDIX
Check-list of deep-water turrid gastropods from Indonesia
To estimate the richness of the turrid fauna of Indonesian waters, and to provide a basis for further research, it
seems useful to give here a check-list of deep-water turrid gastropods presently known from Indonesia. This list
includes species recorded at depths greater than 200 m, in the area within the political borders of Indonesia. A total
of 92 species are listed.
The taxonomic position of species has been re-evaluated, when possible, but brief descriptions and poor
illustrations of some species allow to allocate them only tentatively to genera, awaiting the examination of
respective type material.

INTRODUCTION
The octopod fauna of the tropical Indo-West Pacific region is still poorly known, despite many species having
high profiles in commercial and subsistence fisheries. Recent research into shallow-water octopuses of this region,
particularly the Indo-Malayan region, has encountered a diverse, largely undescribed fauna (NORMAN, 1992a,
1992b, 1993a, 1993b, 1993c, 1993d; Norman & Hochberg, 1994; Norman & Sweeney, 1997; Norman, in
press).
Octopuses from beyond the continental shelves (> 200 m) in the Indo-West Pacific have received even less
attention than shallow taxa. This is a product of the few deep-water surveys undertaken in this region and/or the
limited retention of cephalopod material on such cruises. The expeditions of the "Dana" (THORE, 1949) and
"Siboga" (Adam, 1954) are two of the few exceptions. ROBSON (1925, 1932), Voss (1967, 1988a, 1988b) and
NESIS (1987) provided reviews of deeper sea octopods of the world, collating available information on animals
found at such depths. These authors recognised that the majority of described species are based on limited (often
poorly preserved) material, from few stations. Few works have provided detailed morphological comparison of
species occurring in deeper waters [exceptions being Voss & Pearcy (1990) and Lu & Stranks (1994)].
In 1991, French-Indonesian collaboration resulted in the KARUBAR research cruise to the Banda and
Arafura Seas. A series of 91 benthic trawl stations were carried out employing the Indonesian research vessel,
"Banina Jaya /”, at depths between 100 and 1250 metres. Material collected through this cruise is lodged in the
collections of the Museum National d’Histoire Naturelle, Paris (MNHN) and the Puslitbang Oseanologi - LIPI
Jakarta (POLIPI).
In a visit to the Paris museum by the first two authors in November 1995, octopod material collected through
the Karubar cruise was examined. Benthic (incirrate) octopuses originated from 18 stations at depths ranging
between 199 and 869 metres. Finned octopods (Cirroctopoda) were also encountered at a number of stations and
this material will be treated elsewhere.
MATERIAL AND METHODOLOGY
Trawls were carried out on board the “ Baruna Jaya 1 ” from October 22 to November 5, 1 99 1 . Four gear types
were employed of which 3 captured octopods: Waren dredge, (Drague Waren, station code: DW), Beam trawl (chalut
a perche, station code: CP) and shrimp trawl (chalut a panneaux [crevettes], station code: CC). All molluscs

State of maturity is divided into 3 stages: Immature (or juvenile), Submature and Mature. In immature material
reproductive organs are not visible or tiny. Submature specimens have developed reproductive ducts (visible as
distinct terminal organ or oviducts), but lack spermatophores or a swollen ovary. Mature females possess a large
ovary, which occupies one-third or more of the mantle cavity and contains distinct individual eggs (shown for
large- or small-egg species in Fig. If).
Diagnoses and descriptions presented here are based on submature and mature specimens. Data for juvenile
material is not included as counts and relative measurements (such as sucker counts and arm lengths versus mantle
length) undergo considerable ontogenetic change in the early growth stages and can cause overlap in otherwise valid
diagnostic characters. Weights are presented for specimens preserved in 80% ethanol.
RESULTS
A total of 37 specimens of 6 species of octopods were collected from between 200 and 900 metres. Of these
species, sufficient material for 5 species was available to enable description and treatment here, including 2 new
species.
A single submature male (21.8 mm ML) of an additional species of the genus Octopus was encountered in
material from Karubar station CP 84, off the Tanimbar Islands between 246 and 275 metres. It is distinct from
the new species, Octopus pyrum, in possessing significantly shorter arms (-2 times mantle length) and a
distinctive large pink leucophore on the posterior tip of the mantle. It lacks the diagnostic band of founder
chromatophores found on the ventral mantle of O. pyrum. The submature state and poor condition of this
specimen, however, prevents identification.
Additional material of 2 species collected from the same or adjacent regions were encountered in the collections
of two Australian museums: the Northern Territory Museum in Darwin (NTM) and the Museum of Victoria
Melbourne (MV).
Species collected in the Karubar cruises and housed in the Museum National d'Histoire Naturelle, Paris and
the Puhtsbang Oseanologi, Jakarta, are presented below, with depth ranges:

REMARKS. — Adam (1954) reported four specimens of Benthoctopus from the “ Siboga ” Expedition in
Indonesian waters (in the region covered by the 1991 KARUBAR cruise), which he treated as 4 distinct undescribed
taxa (species A-D). Collection depths ranged from 304 to 1886 m. Only Adam’s Benthoctopus sp. C, a female,
shows similarities with the species described here, matching gill counts and radula dentition, and sharing similar
arm lengths (longest 2.9 times mantle length), web depths (deepest 36% of longest arm) and dark skin colouration.
Adam provides no details of funnel organ shape.
Adam’s remaining species are distinct from B. karubar. Benthoctopus sp. A (female from 304 m) possesses a
W-shaped funnel organ. Benthoctopus sp. B (male from 1886 m) has a distinctive radula with very large first
lateral teeth (ADAM, fig. 36). Benthoctopus sp. D (female from 1158 m) possesses a much lower gill count, 5-6
lamellae per demibranch. Benthoctopus sp. C, collected from 794 m at 7°24’S, 118°15.2 E, was also the only
specimen of the 4 to fall within the depth range of 400-800 m reported here for B. karubar.
As noted by NESIS (1987), the genus Benthoctopus is poorly studied. Most species are ill-defined with the pro¬
posed diagnostic characters often overlapping between taxa. Of the described species of Benthoctopus, only six
species share with B. karubar a UU-shaped funnel organ and the absence of distinctly enlarged suckers in either sex.
These taxa are compared to B. karubar in Table 3 (p. 380). The only described species close to the new species
treated here is B. levis, described from the Antarctic waters surrounding Heard Island in the southern Indian Ocean.
Benthoctopus karubar females lay large eggs (at least 14 mm long) and hence hatchlings would be benthic
with limited capacity for dispersal. The distance between records for these 2 taxa, coupled with temperature
differences between Antarctic waters and those of the Banda and Arafura Seas, are sufficient to consider these
SPCV0SS & PEARCY (1990) reviewed members of the genus Benthoctopus and described 5 new species from
the north-east Pacific Ocean. All are distinct from Benthoctopus karubar, as all possess a W-shaped tunnel organ.
The systematics of the genus Benthoctopus and its relationships with members of the genus Bathypolypus
Grimpe, 1921 require significant revision. Members of the genus Benthoctopus , as it currently stands, are
primarily grouped on the basis of a single character, the absence of a functional ink sac. It is likely that ancestral
octopuses of different shallow-water lineages have been convergent in loss of the ink sac as their ancestors shifted
to lightless depths (where an ink sac offers no selective advantage). It is possible that this genus, as it currently
stands, will prove to be polyphyletic.
ETYMOLOGY. - This species derives its names from the 1991 Karubar cruise, during which the known
specimens were collected.
DISTRIBUTION. - Benthoctopus karubar is reported here from the Arafura Sea, Indonesia (near Kai and
Tanimbar Islands). Material examined here was collected between 400 and 800 m.

Remarks. — The mature male specimen from off north-east Australia matched the Indonesian material in all
characters and is accordingly included here. This specimen is slightly distorted but still possesses the diagnostic
ligula, ventral mantle founder chromatophores, leucophores and matching sucker and gill counts.
There is only one recognised taxon which shows similarities with Octopus pyrum. The distinctive pear-shaped
ligula with the swollen basal edges (Fig. 5e) shows some similarities with that of Bathypolypus valdiviae
described by Thiele (in Chun, 1915, pi. LXXX) from 500 m on the Agulhas Banks, off South Africa. These two
taxa, however, are easily distinguished by the following characters in B. valdiviae : absence of an ink sac and crop
diverticulum; a VV-shaped funnel organ; shorter arms (twice mantle length); deeper webs (33-40% of longest arm);
larger ligula (13-18% of hectocotylized arm) and a radula with a rhachidian tooth which lacks lateral cusps.
ETYMOLOGY. — Derived from the Latin pyrum meaning "pear", which refers to the distinctive pear-shaped
ligula of this species.
DISTRIBUTION. — Octopus pyrum is reported here from the waters of the Banda and Arafura Seas, Indonesia
(from off the Kai and Tanimbar Islands) and north-east Australia (off Townsville, Queensland). Indonesian material
was trawled from between 329-389 m, while the male specimen from off Townsville, Australia was collected from
511m.

Digestive tract illustrated in Fig. 9a. Anterior salivary glands small, less than 20% of length of buccal mass.
Posterior salivary glands moderate sized (longest dimension almost equal in length with buccal mass,
approximately 40% of digestive gland length). Crop swollen, but not distinctly branched to form a diverticulum.
Stomach bipartite. Caecum coiled in single whorl, distinctly striated. Digestive gland approximately ovoid. Ink sac
and anal flaps present. Beaks illustrated in Figs 9b-d. Upper beak with a short, slightly hooked rostrum and
moderate hood (Fig. 9b). Lower beak with rounded rostrum, narrow hood and relatively parallel lateral walls
separated in posterior 15% (Figs 9c-d). Radula with 7 teeth and 2 marginal plates in each transverse row (Fig. 9e).
Rhachidian tooth with 1-2 lateral cusps, typically 1, on each side of large medial cone. Lateral cusps in
symmetrical seriation, migrating from lateral to medial position over approximately 4 transverse rows.
No males encountered in the KARUBAR cruise. A full description of male material from the Coral Sea and New
Caledonia is in preparation.
Submature female genitalia illustrated in Fig. 10a. Ihe
larger female (50.3 mm ML, MNHN 2030) was submature
with a small ovary, but possessed well-developed muscular
distal oviducts. Eggs were forming in clusters throughout the
submature ovary (Fig. 10b). These eggs are already 4 mm
long in this small ovary and would thus be large-type eggs
when mature (>10% of mantle length).
Basal colour crimson brown dorsally and pink ventrally,
formed by tiny crimson chromatophores. Skin sculptured in
numerous small rounded papillae in regular texture over all
dorsal surfaces (Figs 8a, 11c). Few slightly larger bumps
scattered over dorsal mantle. Two long papillae over each eye
(Figs 8a, 8e). Lateral ridge absent.
Remarks. — Considerable confusion surrounds a
distinctive group of mid-depth octopuses, coined here as the
Pteroctopus/Danoctopus complex, identified by the following
diagnostic characters:
- muscular animals with loose, semi-gelatinous skin
sculptured in small and regular low patches,
- distinctive narrow mantle aperture,
- VV-shapcd funnel organ with narrow limbs,
- two narrow elongate papillae over each eye,
- flared web membranes extending to the arm tips, and
- a wide head with small eye apertures.
Members of this group occur in mid-depth habitats from
around 100 to 1000 m in the Atlantic, Indian and Pacific
Oceans. Within this group are two separate subgroups, (1) those species treated under the genus Danoctopus
Joubin, 1933 (and its synonyms Berry a Hoyle, 1939 and Hapaloctopus Taki, 1962) in which the hectocotylus o
males is the third right arm; and (2) others treated under the genus Pteroctopus, where the third left arm ot males is
hectocotylised. A fifth nominal genus within this group, Sasakinella Taki, 1964 is based on a single female
specimen from this group. As no males have been connected with Taki’s type specimen, the status of this generic
name remains unresolved. NESIS (1987) recognised Danoctopus, Pteroctopus and Sasakinella as valid, though ill-
defined, genera containing equally ill-defined species.
The 3 female KARUBAR specimens reported here clearly belong within this complex but were difficult to
identify at both generic and species levels. The absence of male material prevented identification at the generic
level, using the existing generic character of the side of the hectocotylised arm. Identification of these specimens
was resolved on examination of material from comparable depths in the adjacent waters of the Coral Sea and New
Caledonia, housed in MNHN. Amongst this material were numerous specimens from this group, including

4 males, all with the third left arm hectocotylised. This attribute clearly identifies them as members of the genus
Pteroctopus and constitutes the first record of this genus from tropical Indo-West Pacific waters. This
material matched the Karubar females in counts, dimensions, skin sculpture and colour, and we consider them
conspeciftc.
Only 2 species have been coined in the genus Pteroctopus , P. tetracirrhus delle Chiaje, 1830 (described from
the Mediterranean Sea) and P. witjazi Akimushkin, 1963 (described from the Sea of Okhotsk, Russia, far northern
Pacific). NESIS (1987) considers the differences distinguishing the latter species as minor and ill-defined. As a
consequence of this lack of resolution, we have chosen to treat the taxon reported here as an indeterminate species
of the genus Pteroctopus. Material from the Coral Sea and New Caledonia is currently being worked up and species
level resolution for this taxon will be undertaken in that work.
Th^ P'eroctopus/Danoctopus complex requires extensive revision, particularly development of characters which
may aid to identify female specimens of all genera, as well as distinguish species within each member genus.
Distribution. - Karubar material was collected off the Kai Islands, Banda Sea and Tanimbar Islands
Arafura Sea, between 205 and 620 m. Additional material discussed above from the Coral Sea and New Caledonia
was collected between 383 and 600 m.

Stylets, the shell vestige of octopodids, are well developed in Eledone palari. They are keratin-like (non-
mineralised) and approximately one-third of mantle length (21 mm in 62.8 mm ML female).
The inner margin of the mantle aperture is distinct from the form common to other members of the family
Octopodidae. A well-developed flange on the posterior margin of the funnel corresponds with a matching deep fold
inside the anterior edge of the ventral mantle. This structure is reminiscent of the flap-type mantle locking
apparatus found in the pelagic octopods, Tremoctopus violaceus delle Chiaje, 1830 (Family Tremoctopodidae) and
Haliphron atlanticus (Family Alloposidae).
Sucker counts on normal arms are low. Males possess up to 50 suckers proximal to the modified glandular
tips. Females possess up to 76 suckers on the normal arms, which lack the glandular tissue found in the males.
Spermatophores are produced in low numbers (1-5 in storage sac) and are ‘•armed”. The inside of the ejaculatory
apparatus is armed with sharp inward pointing teeth (as for example in Fig. li), which would splay out on the
outer surfaces of the spermatophore on eversion. Mangold (1989) illustrated such armature in the intact and
everted spermatophores of Eledone cirrhosa (Lamarck, 1798). .
The generic status of this octopus requires review as it has a suite of morphological characters distinct from
remaining species of the genus Eledone. All other members of the genus Eledone are restricted to the Atlantic
Ocean and Mediterranean Sea.
DISTRIBUTION — Karubar material was collected from east of the Tanimbar Islands in the Arafura Sea,
between 8°S and 10°S, at depths of around 200 to 300 m. LU & STRANKS (1992) report the distribution of this
species as the continental slope of Australia, from the Great Australian Bight, South Australia north to the
southern Arafura Sea (~10°S), at depths between 1 10 and 620 m. All depth records reported by Lu & Stranks
from shallower than 200 m are from cooler latitudes, south of 26°S.

MATERIAL EXAMINED. — Karubar, Tanimbar Islands : stn CP 78. 284-295: 1 2, 73.2 mm ML (MNHN 20461.
DESCRIPTION. — Counts and measurements are provided in Table 7 (p. 382). Mantle length 73.2 ram, total
length approximately 300 mm, wet weight 165 g. Mantle round and semi-gelatinous with no constriction between
the mantle and the head (Fig. 1 le). Head broad, as wide as mantle. Eyes almost ventro-lateral m aspect. Mantle

transverse flap on funnel, locking into corresponding crease on mantle wall. Arms short, longest 1.7 ' tunes .
Arm formula unclear due to damaged arms in this specimen. Webs deep, >40% of longest arm length. Undamaged
webs of similar depths. Suckers small, 6.0% of ML, first 6 suckers forming a single row from mouth to web
margin, remaining suckers in 2 rows. At least 50 suckers on third arms, with 10-12 tiny suckers on tips. No
enlarged suckers in single specimen. Large W-shaped funnel organ, lateral limbs equal in length with medial ones
(Fig. lie). Gill count 10 in outer demibranch, 9 in smaller inner demibranch. Ink sac and rudimentary anal flaps
present with ink duct emerging anterior to opening of anus. Single female immature, reproductive tract not
developed. Colour pattern: large pink chromatophores on smooth, loose and torn skin. Specimen coated in
coagulated mucous and/or fine mud.
REMARKS. — We follow the works of KRISTENSEN & KNUDSEN (1983) and WiLLASSEN (1986) in adopting
the name Haliphron atlanticus Steenstrup, 1859 as senior synonym over the name Alloposus mollis Verrill. 1880.

ORE (1949) treated this taxon under the name A. mollis, reporting a large submature female (400 mm total
length) from the Banda Sea (05°52’S, 131°14’E), close to the collection site for the Karubar specimen
Our record is based on a single immature female, 73.2 mm in mantle length, -300 mm in total length and
weighing 165 grams. WlLLASSEN (1986) reported two much larger females from off the coast of Norway the
largest being mature at a mantle length over 450 mm and weighing over 4. 1 kg.
Little is known of the biology of this semi-gelatinous pelagic octopus. Thore discussed the funnel locking
apparauis and muscular septa within the mantle cavity of this taxon, stating that “these septa give the impression
at the power of expulsion of water from the mantle cavity must be great, thus making the animal a rather fast

The phylogenetic affinities of the mid-depth KARUBAR species are less clear. Members of the genus
Benthoctopus are reported from throughout the world’s oceans (NESIS, 1987). Benthoctopus requires extensive
revision with most species placed in this genus solely on the basis of absence of an ink sac. As discussed above, it
is premature to discuss phylogenetic affinities of Benthoctopus species.
The new species described here, Octopus pyrum , shows no affinities with any known shallow-water taxa. The
distinctive pear-shaped ligula shows superficial similarities with that of Bathypolypus valdiviae , however the two
species are distinct in a suite of other characters (see above).
As discussed above, the Pteroctopus species reported here belongs in the Pteroctopus/Danoctopus group,
with members occurring in mid-depths (100-1000 m) throughout temperate and tropical latitudes of all oceans.
The wide distribution of this group suggests an older lineage, potentially dating back to times of the circumglobal
and equatorial Tethys Sea, potentially accounting for representation of this group in all oceans at these latitudes.
The anomalous Eledone palari shares a single row of suckers with the remaining members of the genus
Eledone, all of which are restricted to the temperate and tropical waters of the Atlantic Ocean and Mediterranean
Sea. It is distinct, however, in a number of morphological characters, including a different floorplan to the male
reproductive tract, normal octopodid ligula and calamus, spongiform tissue on the modified arm tips of mature
males, deep webs and distinct skin sculpture (regular paired papillae). The generic status of this species requires
revision as it is likely to be distinct from the genuine Eledone , as represented in the Atlantic Ocean.
Eledone palari is restricted to the continental slopes surrounding the entire Australian land mass between 1 10
and 620 m. It produces large eggs (up to 15 mm) and as a consequence its hatchlings would be benthic in habit
with limited capacity for dispersal. The geological stability and isolation of the Australian land mass over the last
350 million years (as it has travelled north from the fragmenting continent of Gondwana) may explain the
distribution and unique nature of this taxon. It is possible that the ancestors of E. palari were carried north on this
migrating land mass from southern polar waters, over sufficient time that direct ancestors of this unique octopus
no longer exist. Conversely, the nearest relatives may prove to be the south polar genera Bentheledone Robson,
1932, Thaumeledone Robson, 1930 and Megaleledone Taki, 1961, all of which share a hectocotylus with well-
developed calamus. All of these genera possess a single row of suckers and occur in deep and cold polar waters
between 800 and 5300 m.
The reported circumglobal distribution of Haliphron atlanticus may reflect its pelagic habit. Nothing is known
of the origins and phytogeny of this distinct animal.
Limited octopod material has been collected from greater depths (>1000 m) in tropical latitudes of the Indo-
West Pacific region. The limited material collected from these depths includes benthic octopuses placed in the
genus Benthoctopus Grimpe, 1921 (e.g., ADAM, 1954), pelagic gelatinous octopuses such as species of Japetella
Hoyle, 1885, Eledonella Verrill, 1884 and Vitreledonella Joubin, 1918 (see THORE, 1949), and finned cirrate
octopuses, such as Grimpoteuthis pacifica (Hoyle, 1885, collected from 4465 m).
The benthic octopod faunas which exist above and below 200 m in this tropical region hence appear
phylogenetically distinct. These differences suggest that there have been no successful regional or recent descents of
shallow-water lines into these darker cooler depths, at least within this region of the Indo-Malayan Archipelago. In
order to further our knowledge of the nature and origins of these little known animals, further sampling, detailed
morphological descriptions and appropriate molecular analyses are all required.

RESUME
De nombreux specimens de Stylodactylidae ont etd rdcoltes, en 1991. aux ties Kai et Tanimbar (Moluques) lors
de la campagne franco-indon6sienne Karubar. Ce materiel renferme huit especes, dont une nouvelle du genre
Parastylodactylus. P. moluccensis. Deux especes sont signalees pour la premiere fois de la region : Parastylodactylus
richeri Cleva, 1 990, et Neostylodactylus affinis Hayashi & Miyake. 1968. Les cinq autres etaient deja connues de la faune
carcinologique indondsienne : Stylodactylus tokarensis Zarenkov, 1968, S. multidentatus Kubo, 1942, 5. libratus Chace,
1983. Parastylodactylus bimaxillaris (Bate, 1888), et Stylodactylus licinus Chace, 1983, cette demure signalec tout
rdcemment par TaKEDA et Hanamura (1994). Par ailleurs, certains specimens, tout d’abord identifies & S. libratus avec
doute et presentant des caractferes qui les rapprochent de Stylodactylus pubescens Burukovsky, 1990, nous posent un
problfeme qui n'a pas trouve de solution satisfaisante ; ils sont cites ici comme Stylodactylus sp. Stylodactylus
brevidactxlus Cleva, 1990, compte tenu de la variability observ6e chez 49 specimens de S. multidentatus Kubo, recoltes
lors de cette campagne, est mis en synonymie avec cette espfece.
Nous avons ajoutd au materiel indonesien, pour chacune des differentes especes, les spdcimens rapportes recemment
de Wallis et Futuna, du Vanuatu et de Nouvelle-Caledonie. Les espbces de ces trois demises regions qui ne figurent pas
parmi celles de la campagne Karubar, sont mentionnees & la fin de cette etude.
ABSTRACT
Crustacea Decapoda: Stylodactylidae collected in Indonesia, the Wallis and Futuna Islands
and the Vanuatu (Karubar, MUSORSTOM 7 and 8 cruises). Additional information on the
Stylodactylidae from New Caledonia.
During the French-Indonesian expedition Karubar off Kai and Tanimbar Islands (Moluccas) in 1991. eight species ot
Stylodactylidae were collected. One of these species, Parastylodactylus moluccensis was new. Two other species.

R. CLEVA
Parastylodactylus richeri Cleva, 1990, and Neostylodactylus affinis Hayashi & Miyake, 1968, are recorded from the
region for the first time and the remaining five species, Stylodactylus tokarensis Zarenkov, 1968, S. multidentatus Kubo,
1942, S. libratus Chace, 1983, Parastylodactylus bimaxillaris (Bate, 1888), and Stylodactylus licinus Chace, 1983, are
already known from the Indonesian area, the last one having been recorded recently by Takeda and Hanamura (1994)
On the other hand, some specimens, at first identified doubtfully as Stylodactylus libratus, and related to Stylodactylus
pubescens Burukovsky, 1990, have been causing trouble to us, and we have not find till now a satisfying solution : they
are mentionned here as Stylodactylus sp. Stylodactylus brevidactylus Cleva, 1990, considering the variability observed
through 49 specimens of S. multidentatus Kubo collected during this cruise, is synonymised with this species.
We added to the indonesian material, for each different species, the specimens collected recently from Wallis and
Futuna, the Vanuatu and New-Caledonia. The species from these three countries which have not been collected during the
Karubar expedition are mentionned at the end of this study.
INTRODUCTION
La campagne franco-indonesienne Karubar, effectuee au large des ties Kai et Tanimbar (Moluques) par le
navire oceanographique Baruna Jaya I ", entre 1 50 et 1 250 m de profondeur, du 2 1 octobre au 6 novembre 1 99 1 , a
rapporte de nombreux echantillons de Stylodactylidae (Crosnier, Richer de Forges & Bouchet, 1997).
D'autres recoltes de specimens appartenant a cette famille ont ete faites, depuis, au large des ties Wallis et
Futuna, lors de la campagne MUSORSTOM 7, effectuee par le navire de FORSTOM, “Alls”, jusqu’a des profondeurs
de 1300 m. du 5 mai au 4 juin 1992 (Richer de Forges & Menou, 1993) et au large de la Nouvelle-Caledonie
lors de di verses campagnes en eaux profondes, toutes faites avec 1’ “Alis” : Beryx 1 1, du 13 au 23 octobre 1992
(Lehodey et all., 1992), Smib 8, du 27 janvier au 2 fevrier 1993, Bathus l,du 10 au 19 mars 1993, Bathus 2,
du 10 au 18 mai 1993, Bathus 3, du 23 novembre au ler decembre 1993, HALIPRO 1, du 19 au 31 mars 1994,
Bathus 4, du ler au II aout 1994 (Richer de Forges & Chevillon, 1996).
A cela s’ajoutent une recolte faite, toujours en Nouvelle-Caledonie, lors de (’expedition MONTROUZIER, a une
profondeur de 52 m (BOUCHET, 1994) et, enfin, des recoltes faites au Vanuatu, lors de la campagne MUSORSTOM 8
eifectuee a bord de 1' "Alis", du 19 septembre au 14 octobre 1994, entre 100 et 1600 m de profondeur (RICHER DE
Forges etal., 1996).
Ce sont toutes ces recoltes qui sont etudiees dans la presente note.
Les specimens etudies sont deposes dans Ies collections du Museum national d’Histoire naturelle a Paris
(MNHN), au Puslitbang Oseanologi - LIPI, a Jakarta (POLIPI) et au National Museum of Natural History a
Washington (USNM).

Le,gra,nd nombre de specimens identifies ici a Stylodactylus licinus (146 au total, dont 92 indonesiens) permet
d ctendre les variations individuelles relevees lors de notre etude de 1990 (Cleva, 1990 : 88), principalement en ce
qui concerne la longueur relative du rostre, ainsi que le nombre de ses epines. C'est ainsi que, sur les 77 specimens
dont le rostre est intact, le rapport des longueurs du rostre a la carapace (LR/LC) varie de 1 ,2 a 2, 1 (moyenne =
environ 1.65), alors qu'en 1990 nous avions releve des variations comprises entre 1,5 et 2,0. On compte de 32 a
6 epines dorsales (moyenne = 38), et de 14 a 29 epines ventrales (moyenne = 20), contre respectivement 34 a 45
et 18 a 27 releves alors (un male d'Australie, etudie en 1994, presente 12 epines ventrales seulement).

Ces chiffres nous permettent de lever l'incertitude concernant l'identification d'un specimen japonais de la baie
de Tosa, prete par K.-I. HayaSHI en 1990, dont le rostre, plus court que celui des specimens que nous avions alors
examines, nous faisait douter du statut exact de cet individu (Cleva, 1990 : 90). Hayashi (1991 : 42) a de
nouveau signale S. licinus du sud de Kyushu, ou une femelle ovig^re a 6t6 capturee a 808-826 m de profondeur.
Les autres differences individuelles relevdes sont les suivantes : absence d'epines supra-orbitaires chez une jeune
femelle indonesienne de 6 mm (station CC 21), et chez un male du Vanuatu de 9 mm (station CC 1056) ; 4£me
pleuron abdominal non termine en pointe (d'un seul cote ou des deux cotes) chez une quinzaine de specimens. Ces
variations ne sont apparemment pas en relation avec la taille des animaux.
La courbure du rostre, plus ou moins accentuee, ne permet pas d'indiquer avec certitude le sexe des specimens :
on peut cependant remarquer que chez les males, et notamment les plus grands, le rostre est presque horizontal,
tandis que sa courbure vers le haut est plus prononcee chez les femelles et les jeunes males.
REMARQUES. — Takeda et Hanamura (1994) ont tout recemment signale Stylodactylus licinus de
l'lndonesie (Mer de Flores, 280 m, 1 9 ov.).
Dans le materiel qu'ils ont dtudie figure egalement un specimen male, identifie Stylodactylus sp. (1994 : 18,
fig. b-c), capture entre 558 et 593 m. II y a tout lieu de penser, a la lecture de leur description et de leurs
remarques, qu’il s'agit en fait d'un exemplaire de Stylodactylus licinus : le rostre plutot droit et plus fin doit
corresponds au fait qu’il s'agit d’un male, de taille moyenne. Un examen de ce specimen s'av&re toutefois
indispensable pour en confirmer l'identification.
Coloration. — La couleur de fond des specimens varie assez sensiblement du rose au rouge (Fig. 4 A-D).
Distribution. — Stylodactylus licinus est connu des Philippines (550-970 m), de la Nouvelle Caledonie
(580-950 m), des lies Chesterfield (650-970 m), du Vanuatu (541-990 m), des lies Fidji (494 m), des lies Wallis et
Futuna (580-900 m), du Japon (432-826 m), de l'Australie (222-1000 m) et de l'lndonesie (280-810 m). La
distribution bathymetrique de l'espece semble concentree entre 500 et 1000 m, les recoltes a des profondeurs
moindres (Australie, 222 m et Indonesie, 280 m) semblant assez exceptionnelles.

Chez les deux males en bon etat, le rapport des longueurs LR/LC est egal ou a peine superieur a 1. Les

592 m, Cleva, 1990 : 91) ; les recoltes de 1991 ont ete realisees entre 285 et 459 m. Cette espece, decrite a partir
d'un specimen male capture en mer de Chine orientale, a 820 m de profondeur, est egalement presente en
Nouvelle-Caledonie (485-850 m) et aux ties Chesterfield (500-570 m).

L'observation de ce materiel complementaire confirme. la encore, la variability intraspecifique importante de
cette espece, et nous a conduit a reconsidercr le statut de Stylodactylus brevidactylus , decrit lors de notre etude de
1990 a Part.r d'un specimen unique, aux dactyles des P3 a P5 particulierement courts par rapport a ce que I'on
observe habituellement chez Stylodactylus multidentatus. Dans les collections etudiees, deux specimens
indonesiens de la station CP 27 montrent cn effet des dactyles courts, mais dont les longueurs relatives par rapport
au propode sent mtermedia.res entre celles notees chez S. multidentatus (CLEVA, 1990 : 102) et celles indiquees
pour S. brevidactylus (Cleva, 1990 : 106) ; ce dernier peut alors etre consid6re comme le terme extreme, observe
jusqu a present pour ce caracterc chez 5. multidentatus et, avec cette hypothese. doit etre mis en synonymie avec
ui. Ceci semble dautant plus justifte que les autres caracteres retenus pour definir 5. brevidactylus (taille des
spinules de ecaille antennaire, longueur relative des pereiopodes) sont, eux aussi, sujet a des variations notables
meme s. une tendance moyenne semble se degager (un releve precis de chaque caractere conduirait de toute evidence
a une combe de Gauss). C est amsi, par exemple, que dans la tres grande majorite des cas, les spinules qui ornent le
bord de 1 ecaille antennaire sont peu nombreuses et de petite taille.

l’oeil est plus volumineux, les epines rostrales plus longues et plus robustes, les epines antennaires et
branchiosteges plus longues. Les spinules qui ornent les ecailles antennaires sont egalement plus longues.
Toutefois, lorsqu’il s’agit de specimens plus grands, les differences sont plus difficiles a apprehender : ainsi le
male 12159 Stylodactylus sp. possede des epines rostrales plus courtes que celles du male 12142 S. libratus
(Fig. 2A et 2B), ce qui contredit ce qui precede. De meme, le volume de la cornee est assez comparable chez les
plus grands specimens (Fig. 2A et 2B, 2C et 2D).
Ces specimens a rostre court ont des affinit^s certaines avec Stylodactylus pubescens Burukovsky, espece
recoltee sur les rides sous-marines de Sala-y-Gomez et de Nasca, au large du Chili, dans l’Est Pacifique, par
545-800 m de profondeur. L’auteur nous a aimablement fait don de deux specimens, un male de LC 9,5 mm et
une femelle ovigere de LC 8,5 mm. Cette espece, tout comme Stylodactylus sp., possede un rostre plus court que
la carapace, arme ventralement de 2 a 4 epines, et des epines antennaires et branchiosteges longues. Compares a
des specimens de Stylodactylus sp. de taille equivalente, ces 2 specimens montrent des epines rostrales
sensiblement plus Fines, un rostre plus recourbe vers le bas, des pereiopodes sensiblement plus longs et plus greles
(Fig. 2E et 2F).
On comprendra dans ces conditions nos hesitations a decider du statut de Stylodactylus sp.
1) Les differences observees avec certains des specimens identifies a S. libratus , les differences de profondeur de
recolte (de 439 a 950 m pour Stylodactylus sp., contre 270 it 610 m pour S. libratus ), les quelques differences
relevdes avec S. pubescens ainsi que l’eloignement des zones de recoltes, font pencher pour l'hypothese d’une
espece nouvelle.
2) Les caracteres intermediaires (et parfois contradictoires) presentes par certains specimens font pencher pour
une seconde hypothese, celle d’une seule espece, 5. libratus , qui presenterait une grande variability intraspecifique,
comme on a deja pu l’observer chez d’autres especes, a laquelle s’ajoute ici une probable variability geographique,
notre matyriel provenant d’lndonesie et de Nouvelle-Caledonie.
La seconde interrogation trouve d'autant plus sa justification que, dans notre travail de 1990, un specimen
recolte a Madagascar par 400 m de fond, identifie S. aff. libratus, n'est peut-etre qu'un exemplaire de l'espece de
CHACE, au rostre sensiblement plus long, et avec des dpines surnumeraires sous l’epine branchiostyge (Cleva,
1990 : 110).
Des informations sur la coloration des specimens, malheureusement absentes actuellement, nous permettraient
sans aucun doute de prendre une decision finale quant au statut reel de ces differents specimens.
Signalons enfin que HAYASHl (1991 : 41) a recemment fait mention d'un specimen male de Stylodactylus
libratus recolty au Japon (Kyushu-Palau Ridge).

Cet abondant materiel (40 specimens) apporte quelques donnees nouvelles sur la variability de l'espece : le
rostre, qui mesure de 1,6 a 2 fois la longueur de la carapace, porte de 18 a 35 epines dorsales (dont 6 a 8 post-
rostrales), et de 5 a 9 epines ventrales (moyennes sur les 29 specimens au rostre intact : epines dorsales : 25 ;
epines ventrales : 6). Les chiffres les plus bas releves jusqu'ici semblent etre ceux d'un specimen australien chez
qui Ton compte 17 epines dorsales et 4 ventrales (CLEVA, 1994 : 62).
II semble se confirmer, par ailleurs, que le rostre est plus incurve vers le haut chez les femelles que chez les
males.
Distribution. — Largement repandu dans l'lndo-Pacifique (Afrique du Sud, Mozambique, Madagascar,
golfe d'Aden, Philippines, Taiwan, detroit de Coree et mer de Chine orientale, Japon, Australie, Nouvelle-
Caledonie, Vanuatu), Parastylodactylus bimaxillaris etait deja connu de la region indonesienne, puisque les types
de Bate ont ete recoltes au nord de la Nouvelle-Guinee. La distribution bathymetrique de l'espece s'etend entre 106
et 608 m.

dactyle 4^6 spinules (6). Le rapport des longueurs propode/dactyle est respectivement de : P3 : 1,8 a 3,1 (2,6) ;
P4 : 2,1 a 3,7 (3,0 a 3,2) ; P5 : 4,7 a 7,4 (6,1 a 6,8).
Le rostre porte 21 a 26 epines dorsales (22 a 25 pour le materiel type) et 3 ou 4 epines ventrales (3), et le
rapport des longueurs du rostre a la carapace varie entre 1,2 et 1,55 (1,35).
COLORATION. — Elle n'est pas tres caracteristique. La teinte generale est rosatre, avec quelques taches plus
rouge ou orange. Des anneaux de couleur rougeatre s'observent sur les pereiopodes (Fig. 4 G-H).
Remarque. — Parastylodactylus richeri est tres proche d'une autre espece aux dactyles des P3 et P4

5 implantees sur le bord dorsal de la carapace, en arriere du niveau du fond de l'orbite), de taille variable et
d implantation irreguliere, et 6 fortes epines ventrales, de taille plus homogene, sensiblemcnt plus longues et plus
robustes que les epines dorsales les plus fortes. Quelques soies plumeuses s’observent a la base ou entre certaines
epines, et d'autres ont probablement du se detacher.
Carapace avec epines supra-orbitaire, antennaire (emoussee), et branchiostege.
Cinquieme pleuron abdominal arrondi, avec unc forte epine sur sa marge posterieure.

pas tout a fait l'extremite de l'ecaille antennaire ; P4 atteint le milieu de l'ecaille et P5 depasse le niveau du premier
tiers de l'ecaille.
De longues soies plumeuses ornent les articles de tous les pereiopodes.
Ischion-merus des troisiemes pereiopodes un peu plus de 2 fois plus long que le carpe (lobe distal compris),
avec une epine ventrale pres de sa base, une epine laterale sub-distale, et une petite epine distale dorsale ;
propode environ 2 fois plus long que le carpe et 4,5 fois plus long que le dactyle ; dactyle avec 3 ou 4 spinules
ventrales.
Ischion et merus des quatriemes pereiopodes completement fusionnes (pas de ligne de suture visible), plus de
2 fois plus longs que le carpe ; merus avec une epine laterale sub-distale et une petite epine dorsale distale ;

Le paratype differe de I'holotype par quelques points de detail :
— Telson avec 2 rangees de 4 et 5 epines dorsales.
— Pereiopodes un peu plus courts (par rapport a l’extremite de l'ecaille antennaire).
— Rapport des longueurs ischion-merus/carpe des trois dernieres paires de pereiopodes sensiblement plus

CONCLUSIONS
Le grand nombre de specimens de Stylodactylidae recoltes lors de ces campagnes, permettent d'apporter une
interessante contribution a la connaissance de cette famille, tout en laissant apparattre la complexity de la definition
de certains taxons. Ainsi :
— Une espece nouvelle, Parastylodactylus moluccensis, de I'lndonesie, est decrite.
— La distribution geographique de plusieurs autres est etendue ou leur presence, supposee, confirmee :
Stylodactylus licinus a Wallis et Futuna et au Vanuatu, S. multidentatus au Vanuatu, Stylodactylus macropus au
Vanuatu, Neostylodactylus affinis en Indonesie et au Vanuatu, N. amarynthis en Nouvelle-Caledonie,
Parastylodactylus bimaxillaris au Vanuatu, P. richeri en Indonesie et au Vanuatu, P. sembiatae a Wallis et Futuna
et au Vanuatu.
— La variability intraspecifique de plusieurs especes (Stylodactylus licinus, S. multidentatus, Parastylodactylus
bimaxillaris, notamment) est dysormais mieux connue, grace aux importantes series de specimens recoltees.
Cette variability apparait parfois tres importante : il suffit de voir dans quelles proportions varient, pour une
meme espece, la longueur relative du rostre ou le nombre de ses epines (pour ne citer que cet exemple facile a
observer) pour s'en convaincre. Elle nous a ainsi conduit a mettre en synonymie Stylodactylus brevidactylus
Cleva, 1990, decrit a partir d'un seul specimen aux dactyles notablement courts, avec S. multidentatus. Elle nous
conduira peut-etre, aussi, a mettre en synonymie avec 5. libratus, dont le materiel type est reduit a un specimen
unique, ou avec S. pubescens, les exemplaires identifies dans un premier temps a 5. libratus avec des reserves, et
separes provisoirement sous l'appellation Stylodactylus sp.
Dans le meme ordre d'idees, des series suffisamment importantes de specimens de differentes regions s'aveirent
indispensables pour mieux evaluer une probable variability geographique souvent seulement pressentie, et qui nous
conduira peut-etre h reconsiderer le statut de certains specimens.
— La coloration de deux especes, Neostylodactylus affinis et Parastylodactylus richeri, inconnue jusqu'a
present, est indiquee. II est vraisemblable que, compte tenu de ce qui a ete dit plus haut, beaucoup d'incertitudes et
de questions restant en suspens pourraient etre rysolues si Ton disposait d'informations sur la couleur des animaux
recoltes, particuliyrement dans les cas ou apparait un dessin caracteristique.

ABSTRACT
The lobsters collected by the Karubar cruise from Indonesia are examined. Twenty-one species are identified, ten of
which being newly recorded in Indonesia. Moreover, the Karubar cruise obtained an intact specimen of Metanephrops
arafurensis (de Man, 1905) and a re-description is given for this poorly known species. The four species groups in
Metanephrops are redefined and a revised key to the species of Metanephrops is provided.

INTRODUCTION
The Karubar cruise in 1991 collected a number of deep-sea lobster specimens from Indonesia. The material is
found to contain five species of palinurids, five species of scyllarids and 1 1 species ot nephropids. Although no
new species were found, the Karubar material extends the known distributions for many species, such as
Linuparus trigonus (von Siebold, 1824), Palinustus unicornutus Berry, 1979, Ibacus pubescens Holthuis, 1960,
I. novemdentatus Gibbes, 1850, Nephropsis acanthura Macpherson, 1990, N. holthuisi Macpherson, 1993,

N. serrata Macpherson, 1993. N. stewarti Wood-Mason, 1872, N. sulcata Macpherson, 1990, and Metanephrops
australiensis (Bruce, 1966). The most interesting finding is a complete specimen of Metanephrops arafurensis (de
Man, 1905), which was previously known only from a mutilated type. Together with the additional knowledge
gained of the characteristics of the other Metanephrops species, their relationships are discussed and a revised key
to the species of this genus is provided.
MATERIAL AND METHODS
The specimens used in the present study are deposited at the Museum national d'Histoire naturelle, Paris
(MNHN), Puslitbang Oseanologi-LIPI, Indonesia (POLiPI), National Taiwan Ocean University (NTOU), National
Museum of Natural History, Washington, D.C. (USNM), Nationaal Natuurhistorisch Museum. Leiden (RMNH)
and Zoologisch Museum, University of Amsterdam, Amsterdam (ZMA). Furthermore, the collections of the
MNHN and NTOU contain 15 of the 18 known species of Metanephrops. Only three species, namely M.
binghami from the Caribbean, M. motunauensis and M. challenger i from New Zealand have not been examined.
Their characteristics are mainly by referring to Yaldwyn (1954), HOLTHUIS (1964, 1991), JENKINS (1972) and
Takeda (1990).
The terminology used for the body parts of Nephropsis mainly follows MACPHERSON (1990), while that for
Metanephrops follows CHAN & Yu (1991). The measurements are of carapace length (cl) which is measured along
the dorsal midline from the postorbital margin to the posterior margin of the carapace. Only restricted synonymies
of Indonesian records and important works on the species are given.
In the lists of material, CP = beam trawl, CC = shrimp otter trawl, DW = Warren dredge.

Remarks. — P. unicornutus was previously thought to be restricted to the eastern coast of South Africa.
Recently, however, it was found that this species actually has a wide distribution in the Indo-West-Pacific (Chan
& YU, 1995).

Remarks. — Similar to P. unicornutus, recent finds show that this species is also widely distributed in the
Indo-West-Pacific (Chan & Yu, 1995). Nevertheless, its occurrence in Indonesia had already been suggested by
Holthuis (1991).

REMARKS. — This species is widely distributed in the Indo-West-Pacific (from 274 to 536 m deep) and has
been reported from Indonesia by HOLTHUIS (1991). The specimen from Stn CP 88 has the body spines and
pleopods exceptionally long and was collected from great depth (1 188-1178 m). Since the arrangement of the
spines on body in this specimen is very similar to those of the other juveniles of this species, it is probably still
in the very early puerulus stage.

material the number of posterolateral teeth on the carapace may be as high as 18 (12-17 in HOLTHUIS, 1985). As
mentioned by HOLTHUIS (1985), the teeth on the anterior margin of the distal antennal segment are sometimes
strongly reduced in the males. This species has been reported from the South China Sea, the Philippines,
Indonesia and New Caledonia (at depths of 186-457 m).

Remarks. — This present form differs from the typical I. ciliatus (von Siebold, 1824) by having the entire
body distinctly pubescent and slightly more posterolateral teeth on the carapace (one Karubar specimen even has
15 posterolateral teeth on one side). The typical form has a northern distribution, from Japan to the South China
Sea and northern Philippines. The pubescent form has been found in the southern range of the distribution of the
species (i.e. southern Philippines and NW Australia), but is only reported for the first time from Indonesia here
Similar to the figure provided by HOLTHUIS (1985, 1991), the posterior margin of abdominal tergite V is evenly
serrated in the Karubar material. However, all the specimens from Taiwan have the posterior margin of abdomi¬
nal tergite V provided with only three or four distinct tubercles near the lateral ends (Chan & Yu, 1993: 187-
upper photo). The figures of/, ciliatus ciliatus given by HOLTHUIS (1985, 1991) also show a similar arrangement
ol tubercles on abdominal tergite V. Thus, it seems justifiable to treat the pubescent, southern form as a distinct
species, rather than subspecies, as in the comparable situation of Metanephrops velutinus and M. andamanicus It
is interesting that material from the Philippines to Australia often has the body more pubescent.
The depth range of this species is from 151-391 m (HOLTHUIS, 1985).

REMARKS. — These two specimens are very young juveniles (probably at the very early postlarval stages). No
trace of gonopores is found and their pleopods are extremely long. The thoracic sternum has the anterior process
undeveloped (i.e. anterior end of the thoracic sternum truncate and not anteriorly protruded at all) and bears a pair of
elongate posterolateral spines. The juvenile of S. cultrifer collected by the Karubar cruise (see below) has a
similar size but the pleopods are rudimentary and the anterior extremity of the thoracic sternum already shows the
characteristic shape of the species. Thus, it is highly likely that these two small specimens are the juveniles of a
large Scyllarus species. They show some similarities to S. crenatus (WHITELEGGE, 1900), described from East
Australia, in possessing a distinct rostrum, the arborescent markings on the abdomen being indistinct (almost
absent in one specimen) and only the posterior margins of abdominal somites I to III medially incised. S. crenatus
is still known only from the types and it is also likely that WHlTELEGGE's (1900) specimens (about cl 5.2 mm)
are juveniles of other species. This situation is further complicated because the taxonomic status of many species
of Scyllarus is still unclear.

REMARKS. — S. cultrifer is unique in the genus by having both the pereiopods III and IV subchelate. This
species is widely distributed in the Indo- West- Pacific (from littoral to about 290 m deep). HOLTHUIS (1960)
assigned the southern material (i.e. from the Philippines, Indonesia and east of South Africa) to a distinct
subspecies, S. cultrifer meridionalis Holthuis, 1960. However, the KARUBAR specimen shows intermediate
characters between the typical and southern forms. Its posterior margin of abdominal tergite IV lacks a median
incision but the other characteristics all conform to the typical form. As suggested by Harada (1962) and Chan
and Yu (1993), it may not be necessary to divide this species into two subspecies. S. cultrifer has already been
reported by Bate (1888, under the name "Aractus sordidus ") from the Kai Islands.

Remarks. — Although this species is widely distributed in the Indo-West-Pacific (at depths of 720-1305 m),
it is here recorded for the first time from Indonesia. N. acanthura is distinct in having an erect basal spine on the
telson and can be distinguished from the closely related species N. occidentalis Faxon. 1893, from the eastern
Pacific by the rostrum being distinctly longer than one-half the carapace length. The size of N. acanthura is also
smaller than its eastern Pacific counterpart. However, the carapace is not granulate in the Karubar specimens and
that of the female is rather heavily pubescent. Furthermore, the carapace of the male has some post-supraorbital
spinules which are lacking in the female (see also GRIFFIN & Stoddart, 1995).

Macpherson (1990), except that the outer spine on the terminal half of the carpus of large chelipcd is absent in
one specimen and poorly developed on one side in the other. The smaller male also has the left anterior spine of
the subdorsal carina missing.

Remarks. — This species is extremely similar to N. rosea Bate, 1888, from the western Atlantic.
Macpherson (1993) only used the relative position of the gastric tubercle on the carapace to separate them. Other
than being smaller in size, the Indo-West-Pacific material appears to have the anterior margin of the abdominal
pleuron II slightly more convex and the large chelae less granulate [three specimens of N. rosea from French
Guyana (MNHN-AS 574) were compared]. Since, at present, only six specimens are known from
north-western and eastern Australia and Indonesia (at depths of 603-1105 m), more material is necessary to
determine the taxonomic status of this Indo-West-Pacific form.

Remarks. The present species is very similar to N. steward and they often occur together. Nevertheless,
M serrata differs constantly from the latter species in having some additional spines on the subdorsal carina Thus
the Stboga" specimen reported by DE Man (1916) from the Kai Islands has the subdorsal carina denticulate and
should belong to the present species instead of N. steward. The size of N. serrata is also much smaller than that of
N. steward. However, the differences in the rostral length and large chela between these two species, mentioned by
Macpherson, (1993), appear to be rather variable in N. steward.
N. hamadai Watabe & Ikeda, 1994, recently described from Japan, is very similar to N. serrata. The characters,
such as the shape of the coxae of the pereiopods and the relative distances of the orbital margin, cervical groove
and posterior margin of the carapace, used by Watabe and Ikeda to distinguish N. hamadai from N. serrata are
found to be very vanable in the Karubar and North Western Australian specimens (10 specimens in NTOU,
CSIRO in exchange). It is highly likely that N. hamadai belongs to the same species as N. serrata.

However, the previous record in Indonesia by DE MAN (1916) actually represented N. serrata. Thus, it can be
considered that N. stewarti is correctly reported from Indonesia only now. N. stewarti is probably the largest
species of the genus, the body length (excluding the rostrum) of a male collected by the Karubar cruise reaching
18.2 cm.

Remarks. — N. sulcata is widely distributed in the Indo- West-Pacific but has not been recorded in Indonesia
before. Moreover, one lot of the Karubar specimens (Stn CP 81) was collected at a depth of only 200-207 m
which is much shallower than previously thought for N. sulcata (415-1 1 1 5 m deep in MACPHERSON, 1990, 1993).
It is found that some characteristics used by MACPHERSON (1990) to separate N. sulcata from the closely
related Atlantic species N. atlantica Norman, 1882, are not very satisfactory [specimens of N. sulcata and
N. atlantica in MNHN, mentioned by MACPHERSON (1990), have been compared]. The dorsal carina on the
abdomen is also very distinct and the median groove of the rostrum may sometimes overreach the distal rostral
teeth in the material from the Atlantic. On the other hand, the distance between the post-supraorbital spine and the
gastric tubercle is often more than 0.5 (to about 0.6) times the distance between the gastric tubercle and the post-
cervical groove in the Indo-West-Pacific material. Nevertheless, the size of Indo- West-Pacific specimens appears to
be much smaller than that of the Atlantic material and the carpus of pereiopod II is always shorter than the palm.
Furthermore, the posterior border of the abdominal somite V often bears a distinct spine in the Indo-West-Pacific
specimens, but this spine is usually absent in the material from the Atlantic.

Description. — Carapace spinulose. 4-5 post-rostral teeth present. Region between post-rostral carinae only
having some spinules on posterior part. Posterior margin of hepatic groove spinulose, but that of cervical groove
lacking spines except those at anterior ends of post-cervical ridges. Three lateral, post-cervical ridges present.
Antennal spine wing-like and with outer margin somewhat crenulated. Distal segment of maxilliped III rather long
and slender. Large cheliped weakly ridged but covered with sharp tubercles, with inner margins bearing some large
spines, and outer margin of chela angular.
Abdomen with distinct dorsal carina (that of somite I with only anterior end present); raised parts naked but
depressed parts heavily pubescent; tergite I with deep, but short, lateral transverse furrows; tergites II and III with
broad but medially interrupted transverse furrows (as wide as or wider than main facade and having intermediate,
narrow, eroded, transverse carina between) and dorsally arched, lateral, longitudinal furrows, submedian notches
rudimentary but some pits may be present on raised parts near dorsal carina; sculpture on tergite IV similar, but
with main facade broader and having more (and larger) pits, while ventral end of lateral furrow recurved
anterodorsally; non-articular surface of tergite V with raised parts less than depressed parts and mainly composed of
an eroded cross at middle; tergite VI with median ridge bearing a pair of submedian spines, as well as strong spines
at both anterior and posterior ends, posterolateral spine well-developed, lateral lobe terminated posteriorly by a
strong spine and outer margin having 2-3 spines. Abdominal pleura ventrally pointed and with margins crenulated.
Telson bearing 3 spinules at middle, with pair of elongate, submedian, basal spines and 2-3 large spines on
dorsolateral ridges. Endopod of uropods covered with spinules and having a strong basal spine, exopod only with
outer part spinulose. Posterolateral spines of telson and uropods all very well-developed.
Coloration. — Body generally orange pink. Eyes dark brown. Anterior carapace somewhat pink. Large
cheliped slightly banded with pale and deep orange bands. Distal 2/3 ol fingers of large chelae and hinges of
abdominal somites whitish.
SIZE. — The two males known are cl 34 mm and 50 mm.
Distribution. — Only known near the Kai Islands in Indonesia, at depths of 443-560 m.
REMARKS. — M. arafurensis was originally described from a multilatcd specimen and no other material had
been obtained since the original description. The finding of a complete specimen (although with left large cheliped
smaller and probably regenerated) of this species by the Karubar cruise is therefore of particular importance.
The Karubar male is almost identical with the type (condition good except for original damage), except that
the right post-rostral carina bears only four teeth (actually the fifth post-rostral tooth is rather small and situated
more medially than the anterior teeth). Aside from lacking pits on the raised parts near the dorsal carina, the
sculpture of the anterior three abdominal somites of the Karubar male is very similar to that of the type.
Although no illustration was given by DE MAN (1916) of the posterior abdomen, a broken abdominal somite IV
and the left third of somite V are present in the type. They are also very similar to those of the Karubar male and
only differ in the arrangement of pits on the raised parts.
Many authors (eg. BRUCE, 1966; JENKINS, 1972; Chan & Yu, 1987; HOLTHUIS, 1991) suspected that
M. arafurensis is most similar to M. auslraliensis. Indeed the spinulation of the carapace is almost identical
between these two species, with only the spines being relatively more well-developed and the post-rostral carina
sometimes bearing one more, small tooth in M. arafurensis. However, the large cheliped and abdominal sculpture
of M. arafurensis are very different to those of M. australiensis. The presence of spinules on the exopods of the
uropods and the middle of the telson also separate the former species from the latter.
The spinulose large cheliped and complicated abdominal sculpture of M. arafurensis show close resemblance
with the fossil species M. motunauensis Jenkins, 1972, from the late Pliocene of New Zealand. The large
chelipeds appear to be almost identical in these two species. The spinulation ol the carapace and ol the tail fan are
also very similar, except that the entire posterior margin of the cervical groove is spinulose in A7. motunauensis.

T.-Y. CHAN
Although M. motunauensis seems to have fewer spinules on the posterodorsal carapace and tail fan, these spinules
may well be eroded and become indistinct in fossils. The clearest difference between M. arafurensis and
M. motunauensis is of the abdominal sculpture. Although the basic patterns of sculpture are similar [although
JENKINS (1972) mentioned a difference in the shape of the lateral longitudinal furrows actually similarly arched
dorsally in both species], the transverse furrows of M. motunauensis are narrow, as in most of the other species of
the genus. However, the transverse furrows are very broad in M. arafurensis with the abdominal tergites IV and V
having many pits and that of the latter even largely depressed. Furthermore, the median ridge of abdominal tergite
VI bears three pairs of submedian spines in M. motunauensis, but the two anterior pairs of spines are represented
by a single, large spine in M. arafurensis.
M. arafurensis seems to be very rare as only one specimen was obtained by the intensive samplings of the
Karubar cruise and the specimen was collected from almost the same location and depth as the type.

Remarks. — It is interesting that the present species was supposed to be endemic to NW Australia (at depths
of 418-500 m), but is now found in Indonesia. Although the specimen collected by the Karubar cruise is a small
juvenile, it has the typical abdominal sculpture of the species, except for lacking distinct pits. However, its
posteriormost post-rostral teeth are situated more medially and the posterior region between the post-rostral carinae
bears more spinules. Moreover, the exopods of the uropods, as well as the middle and lateral parts of the telson,
bear some spinules. These spinules are always absent in larger specimens (i.e. from cl 19.1 mm onwards). The
fingers are also slightly longer than the palm (1.1 times) in the juvenile. Nevertheless, all these different characters
in juveniles may merely represent the ancestral relationships between M. australiensis and M. neptunus.
The northward distribution of M. australiensis actually reaches as far as the Philippines. The Metanephrops
collection in the USNM has a lot of two females obtained by the "Albatross" from the Philippines (USNM
170461) very similar to the present species. The only difference between the two Philippine specimens and the
material of Australia (NTOU and RMNH) is that the lateral abdomen possess rudimentary longitudinal furrows.
These longitudinal furrows on abdominal tergites II and III are quite distinct (though very shallow) in the smaller
female (fig. 4e). Furthermore, the intermediate, eroded carinae within the transverse furrows of abdominal tergite II
are very distinct in this female and the large chelae are slightly more granulate in the Philippine specimens.
Nevertheless, since specimens from Australia sometimes also have rudimentary longitudinal furrows laterally on
the abdomen (fig. 4d) and since these furrows are intermediately developed in the other female from the
Philippines, it does not seems necessary to treat the Philippine material as a different species.
M. australiensis nonetheless mainly occurs in NW Australia. The extensive sampling in the Philippine-
Indonesian region by many large expeditions has so far only obtained three specimens of this species (i.e. one
juvenile by the Karubar cruise and two females by the "Albatross").

Remarks. M. neptunus has been reported in Indonesia by Macpherson (1990), from Makassar. As
mentioned by BRUCE (1965), the anterior transverse furrows of the abdominal tergites II and III are rather variable
in this species. These furrows can be as long as the posterior transverse furrows (i.e. in the two large specimens of
the Karubar and the Makassar specimen) or have the submedian parts variably raised and fused with the main
facades [,.e. in the types, the specimen from Tungsha Tao, the specimen from the Philippines, the small specimen
trom Karubar and some specimens from Australia (Wadley & Evens, 1991 and specimens in NTOU)]. The red
colour of the body also varies a lot in different individuals. Some have the body nearly all red (i.e. the female from
Karubar, which has only the abdominal somites I to IV whitish, fig. 5 c) while some others are mainly white
i.e. the Australian specimen in Wadley & EVANS, 1991). Half red and half white individuals can also be found
(eg. the types, specimens from Tungsha Tao, Makassar, and the Karubar male, fig. 5 d). Since no correlation is
found between colour patterns, shape of the anterior transverse furrows on the abdomen, localities, depth and sexes
they probably represent natural variations of the species.
Apart from its huge size and presence in deeper waters, the general appearance of M. neptunus rather differs
rom all the other species of the genus [eg. smaller eyes, only two lateral post-cervical ridges, large chelae with
fingers considerably longer (1.3- 1.5 times) than palm, each of abdominal tergites II to V bearing Two transverse
furrows etc.] The small juvenile obtained by the Karubar cruise already has all these "aberrant" characteristics
hus, although juveniles of M. austrahensts show some resemblances with M. neptunus. they can be readily
distinguished from each other. y
Although M neptunus ris widely distributed from the South China Sea to western Australia (at depths of 300-
m and usually more than 500 m) and has a very large size (body length reaching 25 cm in Holthuis, 1991)

REMARKS. — M. sibogae is very similar to M. boschmai (Holthuis, 1964) but is generally considered to differ
in the inner margin of the merus of the large cheliped lacking large spines (HOLTHUIS, 1964, 1991; Chan & Yu,
1987). However, 1-3 large spines are found on the merus of the large cheliped in 23 of the 32 specimens collected
by the Karubar cruise. Therefore, the use of the spinulation on the large chelipeds to separate these two species
is not at all satisfactory. Nevertheless, a direct comparison of some M. boschmai specimens from western
Australia (NTOU and 6 paratypes at RMNH) shows that several constant differences can be found between the two
species (see also Griffin & Stoddart, 1995).
The posterior margin of the hepatic groove always bears 4-6 spinules in M. boschmai, while these spinules are
lacking in all the M. sibogae specimens examined. Furthermore, there are 1-5 additional spinules present around
the dorsal postorbital spines in M. boschmai and these spinules are usually absent in M. sibogae (only two
specimens have an additional spinule on one side of the carapace). The paired spines on the dorsal post-cervical
ridge are well-separated in M. boschmai, but abutting in M. sibogae. The median ridge of abdominal tergite VI is
generally armed with a pair of submedian spines in M. boschmai, but only a single median spine in M. sibogae.
Very rarely (2/32) an additional pair of posterior submedian spinules may be present in M. sibogae (as shown in
DE MAN, 1916: pi. 6-fig. 18) though these are always smaller than the median spine. On the other hand, the
median ridge of abdominal tergite VI may occasionally lack distinct spines in both species. As mentioned by
Holthuis (1946) the distal segment of maxilliped III is more oval in M. boschmai (1.8-2.04 times as long as
broad in M. boschmai and 2. 6-3.2 times as long as broad in M. sibogae). The shape of the scaphocerite, however,
is not very different between the two species as described by HOLTHUIS (1964). The large chela is weakly ridged
and granular (sometimes rather sharp) in adults of M. sibogae, but always rounded and very finely granular in
M. boschmai. Other than inhabiting different regions (i.e. M. sibogae occurs from southern Indonesia to northern
Australia at depths of 246-320 m, while M. boschmai is restricted to western Australia at similar depths), the two
species have very different coloration (see Wadley & Evans, 1991). M. sibogae is rather uniformly orange-pink.
The colour of M. boschmai is much attractive: Its body is also orange-pink but the posterior margins of each
abdominal tergite and tailfan are whitish, while the large chela has the fixed finger red, but the movable finger
whitish. Furthermore, the postorbital margin is deep red in some small specimens of M. boschmai.
The abdomen is generally smooth in the present species. However, sometimes rudimentary, transverse, as well
as longitudinal, grooves, or rows of shallow pits, may be present on the abdomen (also present in M. boschmai,
but usually even less distinct).

Remarks. — The present species was only recently described by Chan and Yu (1991) from the Philippines
and western Australia, where it was previously mistaken for M. andamanicus (Wood-Mason, 1891). The
34 specimens collected by the Karubar cruise in southeastern Indonesia all have the raised parts of the abdomen
coarse and pubescent. The record of M. andamanicus by DE MAN (1916) from the other side of Indonesia was
suspected to represent the present species (Chan & Yu, 1991). However, a re-examination of DE Man's (1916)
specimen {"Siboga": stn 12, Java Sea, 07°15'S, 115°15.6'E, 289 m, 14.3.1899: 1 S 44.9 mm (ZMA)] revealed

that the raised parts of its abdomen are naked and smooth. The Metanephrops collection of the USNM also
contains two M. andamanicus specimens from the Java Sea [Cruise 684, Java Sea, 08°34’S, 1 14°36'E, 322 m,
22.6.1981: 1 S 34.0 mm, 1 2 50.0 mm (USNM 456448)]. Thus, it is possible that M. andamanicus has a
distribution from the Indian Ocean to the western part of Indonesia, while M. velutinus occurs from the
Philippines down to the eastern part of Indonesia and western Australia (at depths of 238-702 m). Material from
intermediate localities, such as the Flores and Banda Seas, will probably provide more insights to the exact
distribution of these two, closely related species. This species was found recently in the Torres Strait.
NOTES ON THE RELATIONSHIPS OF THE SPECIES OF METANEPHROPS
The discovery that the poorly known species M. arafurensis is very similar to the single fossil species of the
genus, M. motunauensis , along with improved knowledge of the species of Metanephrops in recent years (CHAN
& Yu, 1987, 1991, MACPHERSON, 1990), allow a brief revision of the relationships between the species of this
genus.
The number of species (including the fossil species) of Metanephrops has been increased from 14 to 18 since
its erection in 1972. Generally, members of this genus are divided into four groups (DE Man, 1916; Yaldwyn,
1954; JENKINS, 1972; Chan & Yu. 1987; Holthuis, 1991). The "japonicus" group has the carapace smooth,
abdomen conspicuously sculptured and the large chela bearing prominent, spinulated ridges. The "binghami" group
has the carapace finely granulate, abdomen smooth but the large chela with prominent spinulate ridges. The
" arafurensis " group has the carapace spinulose, abdomen with conspicuous furrows and the large chela variably
ridged. The "thornsoni" group has the carapace smooth, abdomen weakly sculptured or smooth, and the large chela
also weakly ridged to smooth.
The division of the genus into these four groups appears to be valid for the 18 species known at present:
The "japonicus" group. — M. japonicus (Tapparone-Canefri, 1873), M. andamanicus (Wood-Mason.
1891), M. sagamiensis (Parisi, 1917), M. formosanus Chan & Yu, 1987, M. mozambicus Macpherson, 1990,
M. armatus Chan & Yu, 1991, and M. velutinus Chan & Yu, 1991.
The "binghami" group. — M. rubellus (Moreira, 1903) and M. binghami (Boone, 1927).
The "arafurensis" group. — M. arafurensis (de Man, 1905), M. neptunus (Bruce, 1965), M. australiensis
(Bruce, 1966) and M. motunauensis Jenkins, 1972.
The "thornsoni" group. — M. thornsoni (Bate, 1888), M. challengeri (Balss, 1914), M. sibogae (de Man,
1916), M. boschmai (Holthuis, 1964) and M. sinensis (Bruce, 1966).
However, the spines and ridges on the large chela are rather small and weak in some species of the "japonicus"
group, such as M. velutinus and M. formosanus. The abdomens of M. mozambicus and M. formosanus lack a
distinct dorsal carina and have the sculpture rather simple (Chan & Yu. 1987, 1991). On the other hand, the large
chela in some species of the "thornsoni" group is somewhat granulate-ridged (e.g. M. sibogae) or has large spines
(e.g. M. thornsoni). Moreover, distinct transverse furrows are present on the abdomen of M. sinensis and
M. thornsoni. Within the ” arafurensis " group, the abdominal sculpture can be very complicated (e.g. M. neptunus
and M. arafurensis) or rather simple (e.g. M. australiensis) while the large chela may be heavily spinulose (e.g.
M. neptunus) or nearly smooth (e.g. M. australiensis).
The spinulation of the carapace, however, appears to be quite constant in separating the species groups of
Metanephrops. The "arafurensis" group has the carapace uniformly spinulose. The "binghami" group has the
carapace rather smooth but the entire posterior margins of both the hepatic and cervical grooves are spinulose. The
carapaces ol the "japonicus" and" thornsoni" groups are smooth, with the posterior margins of the cervical grooves
not serrated. Moreover, the ridging of the large chela appears to have two, somewhat different, forms regardless of
the degree of development of spines on it. In the "japonicus" and "binghami" groups, both the dorsolateral and
ventrolateral margins of the large chela are strongly ridged, making the outer border of the chela a flat surface (that
of the japonicus" group also has a longitudinal, medial depression). On the other hand, the outer border of the
arge che a in the "arafurensis" and "thornsoni" groups is always angular. Although there are large differences in
the complexity of the abdominal sculpture amongst the species of the ' japonicus " and "arafurensis" groups the

furrows on the abdomen are always distinctive in these two groups. Moreover, distinct longitudinal furrows are
present in the "japonicus" group, while the "arafurensis" group usually has some large pits on the abdomen (not
clear in the fossils of M. motunauensis). The abdomens of some species of the "thomsoni" group are sculptured,
but only narrow transverse furrows are present, without large pits on tergites. It should also be noted that the
uropods of the "arafurensis" group are unique in being spinulose. Thus, the definitions of the four species groups
are modified as follows:
"Arafurensis" group. — Carapace uniformly spinulose. Large chela moderately to weakly ridged and from
spinulose to finely granulate, outer border always angular. Abdomen conspicuously sculptured, with or without
deep longitudinal furrows but always bearing some large pits at least in adults (not clear in the fossil species
M. motunauensis). Dorsal surface of uropods spinulose.
"Japonicus" group. — Carapace generally smooth, only bearing some spines on anterior and dorsal parts,
posterior margin of cervical groove not serrated. Large chela ridged and sharply tuberculate to spinulose, outer
border somewhat flat, with a longitudinal medial depression. Abdomen conspicuously sculptured and with deep
longitudinal furrows. Uropods unarmed dorsally.
"Binghami" group. — Carapace generally smooth, but entire posterior margins of hepatic and cervical
grooves spinulose. Large chela ridged and spinulose, with outer border flat. Abdomen not sculptured and uropods
unarmed dorsally.
"Thomsoni" group. — Carapace generally smooth except for some spines on anterior and dorsal parts.
Large chela smooth to weakly ridged, bearing a few large spines; outer border always angular. Abdomen smooth or
bearing only narrow, transverse furrows. Uropods unarmed dorsally.
Since the distinguishing characters previously used for some species are also found to be unsatisfactory (e.g.
M. sibogae vs. M. boschmai and M. thomsoni vs. M. sinensis, etc.), a revised key to the species of
Metanephrops is provided:
1. Carapace rather uniformly spinulose; dorsal surface of uropods covered with spinules .

DEPTH AND GEOGRAPHICAL DISTRIBUTIONS OF THE SPECIES OF METANEPHROPS
Figures 3 and 4 show the known vertical and geographical distributions for the species of Metanephrops
embers of the japonicus group have the widest distribution in the Indo-West-Pacific. The "binghami" group is
PALINURIDAE, SCYLLAR1DAE AND NEPHROPIDAE FROM INDONESIA
425
restricted to the western Atlantic. Species of the "thomsoni" group mainly occur along the western periphery of
the Pacific, from Japan to New Zealand. The "arafurensis" group has a similar, but more restricted, distribution in
the Philippine-Australian region (with only the fossil species found in New Zealand). Since most ot the species
(1 1 out of 18) are present in the Indo-Malay region, the genus probably originated there. JENKINS (1972) is likely
right in suggesting that the "binghami" group originated from the Indo-Malay region and migrated to the Atlantic
through the Tethys, instead of reaching the Atlantic via southern Africa.

pIG 3. — Vertical disiribution of the extant species of Metanephrops. Thick bars represent main distribution ol the
species.
Amongst the four species groups, the "japonicus" group seems to be the most successful in terms of having
the most species and spread to the other parts of the Indo- West-Pacific. As suggested by JENKINS (1972), the
" thomsoni " group is probably the youngest, and therefore still has a limited distribution. However. I disagree with
JENKINS (1972) when he suggests that members of the "thomsoni" group, by being rather abundant, are actively
displacing species of the other groups north- and southwardly. It is now known that species of different groups are
often found in the same region, and M. australiensis, as well as all the members of the "japonicus group, also
occur in large numbers, being exploited commercially (Chan & Yu, 1987, 1991; Wadley & Evans. 1991,
HOLTHUIS, 1991). On the other hand, species of Metanephrops have rather clear vertical zonations. In the same

region, members of the "thomsoni" group are usually found in shallower waters and those of the "arafurensis"
group in deeper waters, while species of the "japonicus" group occur in between the two (CARTER et al. , 1983;
Anon., 1984; Chan & Yu, 1987, 1993; Wallner & Phillips, 1988).

Crustacea Decapoda: Hermit crabs
of the family Paguridae
from the KARUBAR Cruise in Indonesia

ABSTRACT
The French-Indonesian 1991 campagne to the islands of Kai, Aru, and Tanimbar, part of the Maluku region of
Indonesia, revealed an unexpected wealth of hermit crabs of the family Paguridae. Although only 295 specimens were
collected in depths ranging from 85 to 1024 meters, an incredible 19 genera and 36 species are represented, of which
seven genera and 26 species are described for the first time. Included are the monotypic Alainopaguroides gen. nov„
Enneopagurus gen. nov„ Enneophyllus gen. nov., lcelopagurus gen. nov., and Tarrasopagurus gen. nov., and their
respective new species. The genus Michelopagurus , gen. nov., is established for "Pagurodes" limatulus Henderson, 1888,
and one additional new species, and the genus Pseudopagurus is created for "Pagurodes" piliferus Henderson, 1888, the
last of the original trio of species initially assigned to the heterogeneous Pagurodes. A lectotype for Pagurodes inarmatus
Henderson, 1888, the type species of the now monotypic Pagurodes , is also designated. The genus Turleania is proposed
as a replacement name for Laurentia McLaughlin & Haig.
Of the new genera, three are particularly noteworthy. Not only are Enneopagurus and Enneophyllus just the second and
third genera of the Paguridae to be characterized, in part, by the absence of gills on the third maxillipeds. the latter genus
is unique, at least for the present. Its type species, E. spinirosiris sp. nov., is the first pagurid known to have a well
developed epi-rosiral spine. Alainopaguroides joins that very specialized group of genera distinguished by marked
reduction in the abdomen, accompanied by total loss of male pleopods and reduction in the number of female pleopods.
Two additional genera of this group, Solitariopagurus and Porcellanopagurus, are also represented in the Karubar
collection, each by a new species.
In addition to the new genera, new species are described in several of the less commonly reported genera, e.g.,
Caiapaguroides, Decaphyllus, Catapagurus, and Tomopaguropsis. Although Pagurus is widely represented in the colder
waters, particularly of the northern hemisphere, the discovery of three new species from the restricted geographic region
of the Karubar campagne was unexpected. A third species has been added to, and extends the distributional range of, the
recently described Bathypaguropsis from Australian and New Zealand waters. A new species described in Australerenius
has provided continuity to the heretofore disjunct distribution of this genus. Only one genus, Pylopaguropsis, was
represented entirely by known species.

The Karubar collection is also significant for its number of highly evolved genera. Specifically, development of the
male sexual tube(s) is uncommonly prevalent. In the 19 genera included in the collection, males of 13 develop a sexual
tube on one or both coxae of the fifth pereopods, or nearly two-thirds of the total genera.
All species are fully illustrated and detailed descriptions or diagnoses provided. Keys are provided for the regional
genera and species, including those reported from the Maluku area, but not included in the Karubar collection.

sources, particularly those concerning associations with rhizocephalans, e.g., the "Siboga" (van Kampen &
BOSCHMA, 1925; BOSCHMA, 1931b); MORTENSEN's Pacific Expedition (BOSCHMA, 1931a), and the Danish
Expedition to the Kei Islands (van Baal, 1937), as well as museum collections (DE Man, 1881; Lewinsohn,
1969); however, the most comprehensive report is that of Haig and Ball (1988) from the "Alpha Helix"
expedition. These authors documented the occurrence of 46 marine species (including four new and four left
undescribed); however, most were collected at depths of 20 meters or less; seven genera of the Paguridae were
represented.
It has long been postulated that the most diverse marine faunas are to be found in the tropical oceans, especially
the Indo-West Pacific, but at depths generally less than 200 meters (e.g., Ekman. 1953; BRIGGS, 1974). Within
the Paguridea (sensu FOREST, 1987), most hermit crabs inhabiting these tropical environs were thought to belong
to the family Diogenidae. The hermit crabs of the family Paguridae that were collected during the Karubar
expedition consisted of 295 specimens, all coming exclusively from depths ranging from 85 to 1024 meters. The
assemblage includes an astonishing 19 genera, of which seven are proposed herein, and 36 species, 29 of which are
reported for the first time. More than 65 percent of the species covered by this report were collected from depths in
excess of 200 meters, whereas only four species appeared restricted to more shallow depths.
Of the new genera, Michelopagurus gen. nov., with type species Pagurodes limatulus Henderson, 1888, has
been erected for one of two species originally described in the heterogeneous genus Pagurodes Henderson, 1 888,
but subsequently restricted from that genus by designation of P. inarmatus Henderson, 1888, as the type species
(DE Saint Laurent, 1969). Although the second species, Pagurodes piliferus Henderson, 1888, is not present in
the KARUBAR collection, it is in the interest of stability in nomenclature that a new genus, Pseudopagurodes gen.
nov., also be established for it.
The general terminology used in the species descriptions is that of McLaughlin (1974), with exception of the
fourth pereopods. A distinction is made herein between subehelate fourth pereopods, in which the pereopod is
developed as a prehensile structure by the folding back of the dactyl against the propodus, and semichelate fourth
pereopods, where the ventral margin of the propodus is produced beneath the dactyl to such an extent that flexion
of the dactyl becomes much more akin to the action of a dactyl against a fixed finger of a chelate appendage. Terms

Genus ENNEOPHYLLUS nov.
DIAGNOSIS. — Nine pairs of phyllobranchiate gills; arthrobranchs absent from third maxillipeds. Rostrum well
developed, strongly depressed. Ocular acicles simple. Antennal peduncle with supernumerary segmentation not
clearly evident. Third maxilliped with 1 spine on basis; ischium with crista dentata somewhat reduced, without
accessory tooth (Fig. la). Sternite of third maxillipeds unarmed. Chelipeds unequal, right appreciably larger.
Dactyls of ambulatory legs with spinose ventral margins. Sternite of third pereopods with small anterior lobe.
Fourth pereopods semichelate, with single row of scales in propodal rasp. Fifth pereopods weakly semichelate.
Sternite of fifth pereopods developed as single small lobe.
Coxa of left fifth pereopod in males with elongate, basally stout sexual tube directed exteriorly and curved
dorsally across abdomen from left to right, with few terminal setae; right fifth coxa with gonopore, no apparent
sexual tube; 3 unequally biramous unpaired left pleopods. Females not known.
Abdomen straight; uropods (Fig. Ik) only slightly asymmetrical. Telson with transverse suture very weakly
indicated; terminal margins oblique.
TYPE SPECIES. — Enneophyllus spinirostris sp. nov. Gender masculine.
ETYMOLOGY. — From the Greek ennea meaning nine, and phyllon meaning leaf, and referring to the nine
pairs of phyllobranchiate gills in this genus.
AFFINITIES. — Enneophyllus very closely resembles the other two genera of pagurids now recognized that have
only nine pairs of gills, Enneobranchus Garcia-Gomez, 1988, and Enneopagurus gen. nov. All three are
characterized by the absence of an accessory tooth on the crista dentata of the third maxilliped, an elongate left male
sexual tube, and a subtriangular telson that has the transverse suture faintly, if at all, indicated. However, the three
genera differ fundamentally in gill structure: phyllobranchiate in Enneophyllus, intermediate in Enneobranchus, and
trichobranchiate in Enneopagurus. Additional characters that distinguish the three taxa include: 1) the termination
of the left sexual tube - apparently lacking any terminal setae in Enneobranchus (cf. GARCIA-G6MEZ, 1988), with
a dense fringe of setae in Enneopagurus, but only a very few setae in Enneophyllus-, 2) a distinctive preungual
process at the base of the dactylar claw on the fourth pereopod in Enneobranchus, but lacking in both
Enneopagurus and Enneophyllus-, and 3) subequal chelipeds in both Enneobranchus and Enneopagurus, but
conspicuously unequal in Enneophyllus.
Remarks. — Enneophyllus at present is known only from a single representative of the type species,
E. spinirostris sp. nov. For this reason, no attempt has been made at this time to determine the precise structure
440
p.a. McLaughlin
of the mouthparts in this genus; however, a flagellum on the first maxilliped can be observed without dissection.
The supernumerary segment of the antennal peduncle that is usually calcified and readily apparent is, in this
specimen, represented only as a chitinous area between the third and fourth segments. A character that sets
Enneophyllus apart, not only from Enneobranchus and Enneopagurus , but all other pagurids, is its remarkable
rostral structure. The rostrum is exceptionally well developed, lobe-like, and bent downward over the ocular plate
between the ocular acicles (Fig. lb-c). At least in E. spinirostris a prominent epi-rostral spine is developed.

Color (in preservative). — Calcified integument somewhat iridescent; tint of orange on chelae and proximal
portions of fixed fingers and dactyls, distal portions white; ambulatory legs with tint of orange on dactyls and
distal halves of propodi.
Habitat. — Scaphopod shell.
Distribution. — Known only from the type locality in the Tanimbar Islands, Indonesia; 206-210 m.
Etymology. — From the Latin spina , meaning spine and rostrum , and indicating the presence of the unusual
epi-rostral spine.
Affinities. — While clearly not closely related to any known pagurid taxa, Enneophyllus spinirostris does
possess a number of convergent characters. The shared generic characters have already been discussed. At the
’Jooo C 'eVe1, the °Perculate r‘8hl chela is reminiscent of species of Catapaguroides A. Milne Edwards & Bouvier
1892 and Pylopagurus A. Milne Edwards & Bouvier, 1891. The use of a scaphopod microhabitat is also seen in
some species of Pylopagurus, Orthopagurus Stevens, 1927, occasionally Pagurus species (cf. McLaughlin &
KONISHI, 1994), and the parapagurid genus Tsunogaipagurus Osawa, 1995. The left sexual tube curving over the
abdomen is suggestive of species of Catapagurus A. Milne Edwards, 1880.
Remarks. — The phylogenetic position of this extraordinary taxon cannot be even speculated upon until the
morphology of the female is known, and until sufficient specimens become available to permit a more detailed
study of the mouthparts and "skeletal" anatomy. Nonetheless, in having both reduced gill number and well devel¬
oped sexual tube, it can be hypothesized that the rostral development reflects yet another apomorphic character

PAGURIDAE FROM THE KARUBAR EXPEDITION
443
Genus ENNEOPAGURUS nov.
DIAGNOSIS. — Nine pairs of trichobranchiate gills; arthrobranchs absent from third maxillipeds. Rostrum
moderately well developed, triangular, not deflected. Ocular acicles simple. Antennal peduncle with supernumerary
segmentation. Maxillule (Fig. 2a) with external lobe of endopod somewhat produced, not recurved, but provided
with 2 or 3 moderately long setae. Third maxilliped with at least 1 prominent spine on basis; ischium with crista
dentata moderately well developed but without accessory tooth (Fig. 2b). Chelipeds subequal, right more robust.
Dactyls of ambulatory legs with unarmed or very weakly spinulose ventral margins. Sternite of third pereopods
with subquadrate anterior lobe. Fourth pereopods semichelate; with single row of scales in propodal rasp. Fifth
pereopods semichelate. Sternite of fifth pereopods developed as single small subovate or subcircular lobe.
Coxa of left fifth pereopod in males with well developed, rather stout sexual tube (Figs 3a-b) directed exteriorly
and upward, terminally somewhat spatulate and with fringe of dense curved setae; right fifth coxa with gonopore
and occasionally vas deferens slightly protruded; 3 unequally biramous unpaired left pleopods. Females with paired
gonopores; no paired pleopods, unpaired left pleopods on somites 2 to 5.
Uropods asymmetrical. Telson with transverse suture weakly indicated; terminal margins oblique.
Type Species. — Enneopagurus garciagomezi sp. nov. Gender masculine.
ETYMOLOGY. — From the Greek ennea meaning nine, and pagouros meaning crab, and referring to the
presence on only nine pairs of gills in this genus.
Affinities. — As previously noted, Enneopagurus , Enneophyllus gen. nov. and the Atlantic genus
Enneobranchus share several generic characters, however, none are mutually exclusive. Despite our limited
knowledge of its morphology, Enneophyllus is so markedly different from the other two genera that its shared
characters must be considered convergent.
Differences in gill morphology, terminal setation of the male sexual tube, and the absence of a distinctive
preungual process at the base of the dactyl are sufficient to distinguish Enneopagurus from Enneobranchus ;
however, their overall morphological similarities suggest a generally close relationship. Nevertheless, if gill
number is not considered, Enneopagurus appears even more closely allied to the Indo-Pacific genus, Turleania
nom. nov. Species of both of these genera have trichobranchiate gills, lack an accessory tooth on the crista dentata
of the third maxilliped, and have the well developed male left sexual tube terminating in a tuft of setae (Figs 3a-d).
The two genera are separated, not only by the presence of arthrobranchs on the third maxilliped in Turleania nom.
nov., but by differences in the armature of the dactyls of the ambulatory legs and in setal development of the male
sexual tube. In all known species of Turleania nom. nov. the ventral margins of the dactyls of the ambulatory legs
are each provided with a row of well developed spines; the sexual tube is an elongate, usually somewhat spiraled
structure with rounded tip and sparse terminal tuft of straight setae. The dactyls of the ambulatory legs in
Enneopagurus, however, are either unarmed or have only a very few tiny corneous spinules; the left sexual tube is
moderately short, curved toward the exterior, with a broad, spatulate tip practically obscured by a dense fringe of
curved setae.
REMARKS. — Despite their differences, Enneopagurus and the Atlantic Enneobranchus might be considered
analog genera, set apart from most other pagurid genera chiefly by the absence of gills on the third maxillipeds.
Two additional characters shared by these genera, i.e., lack of an accessory tooth on the crista dentata, and left male
sexual tube closely align them with a second analog pair of Indo-Pacific/ Atlantic genera, Turleania nom. nov. and
Iridopagurus de Saint Laurent-Dechance, 1966a.
Garcia-G6mez (1988) related Enneobranchus to Anapagrides de Saint Laurent-Dechanc6, 1966b (sensu lato)
and Iridopagurus de Saint Laurent- Dechancd, 1966a, noting that all three genera shared the diagnostic characters of
1) a long left sexual tube and, 2) absence of an accessory tooth on the crista dentata. He also believed that they all
possessed "intermediate" type branchiae, defining his term "intermediate" by reference to LEMAlTRE's subsequently
published PhD dissertation (Lemaitre, 1989, Fig. 2I-K). Recently McLaughlin and SANDBERG (1995) showed
444
P. A. MCLAUGHLIN
that DE Saint Laurent- Dechance's (1966b) Anapagrides , as defined by its type species, A. facetus (Melin,
1939), did not correspond to the diagnosis given by its author, nor by DE Saint Laurent (1968b), and emended
Anapagrides to reflect the characters of A. facetus. Subsequently, McLaughlin and Haig (1996) proposed the
genus Laurentia, a name now found to be a junior homonym (see, p. 477) for DE Saint Laurent-Dechance's
(1966b) taxon. Garcia-GCmez's (1988) remarks now apply to Turleania nom. nov.
Enneopagurus, Turleania nom. nov., Enneobranchus, and Iridopagurus appear to form a very cohesive
phylogenetic unit in being four of only five taxa presently known that have a left male sexual tube, but lack an
accessory tooth on the crista dentata. Additionally, species of all four share, albeit not exclusively, elongate
ambulatory dactyls, propodal rasps of the fourth pereopods which consist of a single row of scales, and generally
subtriangular telsons. However, some interesting divergent pathways, both morphological and geographic, should
be noted: 1) gills in species of Turleania nom. nov. are trichobranchiate, as are those of Enneopagurus,, species of
the Atlantic Iridopagurus and Enneobranchus have intermediate gills; 2) the external lobe of the endopod of the
maxillule is well developed, but not recurved, in species of Enneopagurus and Turleania nom. nov., but obsolete
in Enneobranchus (cf. GARCIA-GOMEZ, 1988) and Iridopagurus (cf. Garcia-Gomez, 1983); 3) the rostrum is
triangular and well developed in Enneopagurus and Turleania species, in contrast to the reduced and broadly
rounded rostra of species of both Atlantic genera; 4) the transverse suture dividing the telson into anterior and
posterior lobes is weakly indicated in the Indo-Pacific genera, but apparently absent in Enneobranchus and
Iridopagurus. Although there is a suggested trend toward simplification in morphological structure from Indo-
Pacific to Atlantic in these analog genera, all are still highly complex taxa about which we still have only
fragmented knowledge.

Color (in preservative). — Calcified integument somewhat iridescent.
Habitat. — Variety of gastropod shells.
Distribution. — Kai and Tanimbar Islands; 356-552 m.
Etymology. — The species is named for Dr Julio Garci'a-GOmez, Miami-Dade Community College,
mm!, Florida, not only a friend and colleague, but the first carcinologist to document gill loss on the third
maxillipeds in pagurids.
Aff|N|TIES — Among Karubar species, Enneopagurus garciagomezi bears considerable resemblance to
species of Turleama nom. nov. However, in addition to the characters separating the two genera, E. garciagomezi

is characterized by setose, but unarmed chelae, and ambulatory legs that have little or no armature on the ventral
margins of the dactyls.
Remarks. — The sexual tube in males of this species (Figs 3a-b) tends to be moderately short to moderately
long, thick, curved outwardly and directed dorsally; the tip is spatulate and provided with a dense fringe of curved
setae. Males obviously infected with rhizocephalans still exhibit a well developed sexual tube.

from Stn DW 03: a, c, sternite and coxa of left fifth pereopods (ventral view); b, d, terminal portion of left sexual
tube. Scale equals 0.5 mm (c, d) and 1.0 mm (a, b).
Sexual dimorphism is seen in the left cheliped and in the setation of the sternite of the fifth pereopods.
Although the dactyl and fixed finger of the left chela are long, slender, and venlrally curved in both sexes, the
curvature is usually more pronounced in males where there is also a tendency for the chela to become laterally
twisted. Females have a considerably greater amount of setae on the sternite and coxae of the filth pereopods.
Genus DECAPHYLLUS de Saint Laurent, 1968
Decaphyllus de Saint Laurent, 1968a: 925; 1968b: 1100.

endopodal lobe obsolete or absent. Third maxilliped with crista dentata of ischium reduced, no accessory tooth;
merus with very strong dorsodistal spine. Sternite of third maxillipeds unarmed. Fourth pereopods simple, neither
semi- nor subchelate; without propodal rasp. Sternite of fifth pereopods entire, not divided into 2 lobes by median
groove.
Males with very long sexual tube developed on coxa of right fifth pereopod, directed from right to left across
ventral body surface and curved anteriorly. Coxa of left fifth pereopod with short or moderately short sexual tube
directed from left to right. Females with single gonopore on coxa of left third pereopod.

males. Telson without transverse suture; terminal margin entire or with minute median cleft; posterior lobes
strongly asymmetrical, each with 2 to 4 spines.
REMARKS. — In her revision of the genera Catapaguroides A. Milne Edwards & Bouvier, 1892 and
Cestopagurus Bouvier, 1897, DE SAINT LAURENT (1968a) established the genus Decaphyllus for three previously
unknown species. In that publication, de Saint Laurent presented only a brief generic diagnosis and a slightly

P. A. MCLAUGHLIN
more detailed diagnosis of its type species, D. spinicornis de Saint Laurent. In a subsequent paper she (DE SAINT
Laurent, 1968b) provided a detailed description of the general characters of Decaphyllus , gave full descriptions of
the three species, D. spinicornis, D. similis de Saint Laurent and D. junquai de Saint Laurent, and compared this
rather distinctive genus with its closest cohort, Catapaguroides. Decaphyllus spinicornis is known only from
Japan, whereas D. similis and I), junquai are reported from New Guinea and Indonesia.
Two additional species have been discovered during the course of this study, D. barunajaya sp. nov. and
D. maci sp. nov. Both of these species differ from DE SAINT Laurent's (1968a, b) taxa in having a very
prominent spine on the ventral margin of the first antennal segment. Decaphyllus barunajaya sp. nov. also differs
more notably in lacking arthrobranchs on the third maxillipeds. Gill loss in the Paguridea typically is manifest by
loss of pleurobranchs, from four being present in the Pylochelidae and some diogenids to none in some genera of
the Paguridae. Decaphyllus is only one of four pagurid genera where this total loss of pleurobranchs has been
observed. The tendency toward reduction and/or disappearance in the paired arthrobranchs of the third maxilliped,
without complete pleurobranch loss, has been reported in coenobitids and some pylochelids, but until this present
report was known in the Paguridae, only in Enneobranchus.
Although other characters can be enlisted to justify the establishment of the genera Enneobranchus,
Enneophyllus, and Enneopagurus, loss of arthrobranchs on the third maxilliped is the fundamental character. That
rationale might similarly suggest that a distinct genus be established for D. barunajaya sp. nov., were it not for the
overwhelming number of supplemental characters it shares with the other four species of Decaphyllus. These
include the broadly rounded rostrum; characteristic shape of the ocular acicles; lower ramus of antennular flagellum
with only three segments; distinctive profile of the coxal endite of the maxillule; reduced and irregular dentition of
the crista dentata; absence of an accessory tooth on the crista dentata; loss of the pleurobranch above the fourth
pereopod; uniform armature of the dorsal margins of the carpi of the second pereopods; very specialized develop¬
ment of the dactyl and propodus of the fourth pereopod; length and orientation of both the right and left sexual
tubes; male pleopod development; single female left gonopore; and unusual telson shape and armature. In view of
all these shared characters, clearly a simple emendation of Decaphyllus to accommodate D. barunajaya is the
appropriate action.

COLOR (in preservative). — Shield and cephalic appendages with faint orange hue. Chelipeds and ambulatory
legs mottled orange with white distally on most segments. Calcified integument somewhat iridescent.
Habitat. — Unknown.
Distribution. — Tanimbar and Kai Islands, Indonesia; 184 to 289 m.
ETYMOLOGY. — The species is named for the vessel "Baruna Jaya from which the specimens were
collected.
AFFINITIES. — Decaphyllus barunajaya differs from the other species of the genus in the absence of
arthrobranchs on the third maxillipeds, in having an unarmed dactyl of the right cheliped, two proximal spines on
the dorsal surfaces of the carpi of the second pereopods, and shorter right sexual tube. The slightly dilated corneae,
unarmed ventral margin of the carpus of the right cheliped, and distinctly different telson armature are additional
characters that set D. barunajaya apart from D. spinicornis. Among Indonesian species, it resembles D. similis in
having moderately long ocular peduncles with slightly dilated corneae, but differs in having shorter antennular
peduncles, a bifid dorsolateral distal angle of the second antennal segment, and two rows of spines on the carpus of
the left cheliped. Decaphyllus barunajaya is also readily distinguished from D. junquai by its longer ocular, but
shorter antennular peduncles and armature of the right cheliped. Additional characters that serve to distinguish
Decaphyllus barunajaya from D. maci sp. nov. include the anterior lobe of the sternite of the third pereopods,
which is subsemicircular in the former species, but subtriangular in the latter. The carpus of the left cheliped has
only two to four spines on the dorsolateral margin in D. barunajaya, but five or six in D. maci, and the left chela
exhibits a pronounced hiatus between the dactyl and fixed finger in the former species that is lacking in the latter.

COLOR (in preservative). — Shield and cephalic appendages with faint orange hue. Chelipeds and ambulatory
legs also with faint orange hue, appearing as indistinct bands on most segments. Calcified integument somewhat
iridescent.
Habitat. — Unknown.
Distribution. — Kai Islands, Indonesia; 111-118 m.
Etymology. — This species is named for the late E.J. "Mac" McGEORGE, whose photographs have enhanced
many pagurid reports.
AFFINITIES. — As previously indicated, all known species of Decaphyllus share a considerable number of
morphological characters. In proportions and armature of the cephalic appendages, and armature of the right

cheliped, D. maci most closely resembles D. spinicornis. Both species have relatively long ocular peduncles with
corneae showing no dilation; bifid termination of the dorsolateral distal angles of the second segments of the
antennal peduncles; and antennular peduncles that overreach the ocular peduncles by 0.50 to 0.80 length of the
ultimate segment. Similarly, the right chelipeds of both species have a single small spine on the dorsoproximal
surface of the dactyl and both dorsomesial and median longitudinal rows of spines. However, D. maci also has a
row of small spines on the clearly delimited dorsolateral margin, whereas D. spinicornis is described as having the
dorsolateral margin only weakly delimited and with few scattered spinules. Although both species also have two
rows of spines on the dorsal surface of the carpus, the ventrolateral margin is armed with a few spines in
D. spinicornis, but unarmed in D. maci. Differences are also found in the development of the telson. In D. maci a
small median cleft is sometimes apparent, but even when obscured, there is a distinct separation of right and left
lobes, each terminal margin armed with two or occasionally three small spines in addition to the spine of the
external angle. By contrast, D. spinicornis has only two spines on the terminal margin between the spinose
external angles.
From the remaining species of Decaphyllus , all occurring in Indonesian waters, D. maci is best distinguished
from D. similis by its shorter antennular peduncles, dactyl of the right cheliped having only a single spine on the
dorsal surface, and by having two rows of spines on the dorsal surface of the carpus of the left cheliped. From
D. junquai, this new species is also readily separated by the relative shortness of its antennular peduncles, less
strongly armed right chela, and more strongly armed telson. Like D. spinicornis, the telsons of both D. similis and
D. junquai have only two spines on the terminal margin between the spinose external angles. Decaphyllus maci
bears a superficial resemblance to D. barunajaya sp. nov. in having relatively long ocular and short antennular
peduncles; bifid termination of the dorsolateral distal angles of the second segments of the antennal peduncles;
strong spine on the ventrodistal margin of the first segment of the antennal peduncle; and weak median
calcification of the shield. However, the two species are easily distinguished by the armature of the chelipeds and
the carpi of the second pereopods.

Catapaguroides A. Milne Edwards & Bouvier, 1892: 211 (in part). — Bouvier, 1922: 26 (in part). — de Saint Laurent,
1968a: 927.
DIAGNOSIS. — Ten pairs of phyllobranchiate gills (no pleurobranch above arthrobranchs of fourth pereopod).
Antennal peduncle with supernumerary segmentation. Ischium of third maxilliped with crista dentata more or less
reduced, without accessory tooth. Chelipeds unequal, right appreciably stronger. Carpi of ambulatory legs with
dorsodistal spine. Fourth pereopods semichelate; propodal rasp with single row of corneous scales.
Males with sexual tube developed on coxa of right fifth pereopod, directed from right to left under thorax and
recurved anteriorly. Short tube developed on coxa of left fifth pereopod and concealed between 2 thick tufts of setae
on sternite; unpaired biramous left third to fifth pleopods. Females with single gonopore on coxa of left third
pereopod. No paired pleopods and 4 unpaired, left second to fifth biramous pleopods.
Telson with transverse suture only weakly delineated; posterior lobes not markedly asymmetrical.
Remarks. — Prior to the revisionary work of DE Saint Laurent-Dechance (1966b) and de Saint
LAURENT (1968a), the position of the male sexual tube was often the only criterion used in generic assignments.
Use of the collective possession of a right sexual tube had resulted a heterogeneous conglomerate of taxa assigned
to the genera Catapaguroides, Cestopagurus, and Catapagurus that otherwise shared few characters of phylogenetic
significance. With her redefinition of Catapaguroides (DE Saint LAURENT, 1968a), the genus was left with only
three of its formerly assigned taxa, all with Atlantic distributions. She reassigned three Indo-Pacific species, two
previously included in Cestopagurus and one in Catapagurus to Catapaguroides and described six new species. Five
of these, C. inermis de Saint Laurent, 1968a; C. cristimanus de Saint Laurent, 1968a; C. mortenseni
de Saint Laurent, 1968a; C. melini de Saint Laurent, 1968a; and C. spinulimanus de Saint Laurent. 1968a, occur
in Indonesian waters, although none were collected during the Karubar expedition.

Color. — Unknown.
Habitat. — Unknown.
Distribution. — At present known only from the Tanimbar Islands, Indonesia; 206-209 m.
ETYMOLOGY. — From the Latin declivis meaning downhill or sloping, referring to the strongly sloping
dorsolateral face of the carpus of the right chcliped.
Affinities. — Catapaguroides declivis bears some resemblance to both C. melini and C. cristimanus. From
C. melini, C. declivis differs in having shorter ocular peduncles with more dilated corneae; shorter antennal
peduncles; distinctly different armature of the right cheliped; shorter male right sexual tube; and more strongly
armed telson. Catapaguroides declivis is readily distinguished from C. cristimanus by the longer, more slender
shield of the former species and most specifically, by its narrower and differently armed right chela, which has one
or two dorsoproximal tubercles on the palm and lacks sharply crested dorsomesial and dorsolateral margins.
Catapaguroides declivis is immediately distinguished from the second species of Catapaguroides found during the
Karubar expedition by shape and armature of the carpus of the right cheliped.
REMARKS. — The spines on the dorsomesial margin of the palm of the right chela are stronger, but fewer in
number in the very small, but mature, female (0.92 mm) than in either of the larger males. In the holotype, the
right chela is more strongly twisted, and the row of spines on the dorsal surface of the carpus is composed of
numerous, but irregular, more serrate appearing spines. The characteristic proximomedial tuberculation of the right
chela is a single tubercle in both male and female paratypes, and double in the holotype.

Color. — Unknown.
Habitat. — Unknown.
Distribution. — At present known only from the type locality in the Kai Islands, Indonesia; 205-212 m.
Etymology. — The acronym for the 1991 French-Indonesian expedition to Indonesia.
Affinities. — The operculate shape of the right cheliped of C. karubar suggests a close relationship with
C. cristimanus, another species known only from the Kai Islands region of Indonesia; however the quite different
armature of both chelipeds will immediately separate to two species, as will the armature of the telsons.
Catapaguroides cristimanus has been described as having a longitudinal row of spine on the dorsal midline of the
palm ol the right cheliped and two tubercles on the dorsomesial margin of the palm of the left. The right chela of
C. karubar has only two proximal spines and one mesial marginal spine on the dorsal surface; the left chela is
entirely unarmed. The telson of C. cristimanus is reported to have three long spines on each terminal telsonal
margin, whereas, C. karubar has a single small spine on each margin. As previously noted, the shape and armature
of the carpi of the right chelipeds will immediately separate C. karubar from C. declivis. In the former, the carpus
is subtriangular and armed with very few spines, whereas in the latter species, the carpus is subrectangular and
armed with a complete row of spines on the dorsolateral margin.
Remarks. — Although this species is known from a single female, its assignment to Catapaguroides is
reasonably certain. It shares with other members of the genus, 10 pairs of phyllobranchiate gills, reduced crista
dentata lacking an accessory tooth, and single female left gonopore.

2000 meters in the Red Sea. However, both the recently described, S. triprobolus Poupin & McLaughlin, 1996,
and S. tuerkayi sp. nov. have been collected in relatively shallow depths between 1 1 1 and 400 meters.

distribution. — Presently known only from the Kai and Tanimbar Islands, Indonesia; 1 1 1-212 m.
Etymology. - This species is named for Dr Michael Turkay, Forschungsinstitut Scnckenberg, who first
recognized the distinctiveness of this genus.
Affinities. — Sohtariopagurus tuerkayi bears a strong resemblance to 5. triprobolus from French Polynesia
in the elongation of the rostrum and lateral projections and development of the lateral carapace spines, as well as
the structure of the abdomen, uropods and telson. However, the lateral projections of S. tuerkayi are generally
shorter and stouter than ,n 5. triprobolus ; the antennular peduncles of the former species are appreciably shorter.
t first of the lateral carapace projections also are much smaller in 5. tuerkayi than those of S. triprobolus There
are clear similarities in the shape of the chelipeds of the two species; however, the dorsodistal angles of the carpi
are not developed into wing-like projections in 5. tuerkayi as they are in 5. triprobolus. The dorsal surfaces of
these segments in 5. tuerkayi each have a raised median crest armed with a row of spines or tubercles set off by
one particularly prominent, tuberculate spine in midlength, whereas the median elevations of these surfaces in
5. triprobolus are slight and very weakly armed. The dactyls and propodi of the ambulatory legs of 5. tuerkayi are
approximately equal in length, in contrast to the much longer propodi of 5. triprobolus.

REMARKS. — In the original description of Porcellanopagurus tridentatus Whitelegge, 1900, the author
overlooked the first segment of the antennal peduncle, i.e., the segment upon which the antennal gland opens, and
attributed the armature of the second peduncular segment to the first. Takeda (1981, 1985) and Suzuki and
TAKEDA (1987) may, in part, have followed WHlTELEGGE's (1900) interpretation of the first segment in their
inaccurate descriptions of the segmentation and armature of the antenna of their Porcellanopagurus species. These
authors described the basal segment as having a spinule at its outer distal angle and its inner angle developed
forward as a long lobe to grasp the inner margin of second segment, when in fact it is the second segment that is
so armed, and the third segment that is produced. In P. belauensis Suzuki & Takeda, 1987, the authors further
described the "third segment twice as long as the antennal acicula." Neither the true third nor fourth segments are
illustrated as longer than the acicle (SUZUKI & TAKEDA, 1987, figs 2b-c); only the fifth (ultimate) segment agrees
with that description.
Poupin and McLaughlin (1996) noted that, among other characters, the subchelate fourth pereopods found in
species of Solitariopagurus suggested a closer relationship with Alainopagurus Lemaitre & McLaughlin, 1995,
than with Porcellanopagurus, in which the fourth pereopods are semichelate. The fourth pereopods of
P. truncatifrons Takeda, 1981, were described by the author as having "propodus widened and spatulated; its lower
border fringed with a row of horny curved spines, its distal end being prolonged only slight beyond articulation
with dactylus which is talon-like and curved dorsally." From his figure [Takeda, 1981, fig. 3 (3)], it would
appear that this appendage is inverted, thereby giving the impression of a dorsally directed dactyl; however, the
appendage appears distinctly subchelate.
Reference to the telson has been intentionally omitted in the generic diagnosis of Porcellanopagurus given here.
In most species, a typical pagurid-like telson is developed. However, in two recently described Japanese species,
P. truncatifrons and P. nihonkaiensis Takeda, 1985, telsons apparently are lacking. For P. truncatifrons, Takeda
(1981: 12) commented "It is remarkable that I failed to find the telson, but the presence of marginal hairs along the
posterior border of the penultimate segment may justify the absence of the telson." Takeda (1985) illustrated
only the sixth abdominal somite and uropods, but made no comment about the missing telson in
P. nihonkaiensis. Both of these species are known only from their respective holotypes; therefore, it is not clear
whether this ostensible telson loss reflects evolutionary change or simply injury.

FlABITAT. — Unknown.
DISTRIBUTION. — At present known only from the type locality in the Kai Islands. Indonesia; 205-212 m.
Etymology. — This species is named for Professor Jacques FOREST of the Museum national d'Histoire
Naturelle, Paris, in recognition, not only of his landmark studies of Porcellanopagurus , but his many
contributions to hermit crab systematics.
Affinities. — Porcellanopagurus jacquesi most closely resembles P. japonicus Balss, 1913, P. nihonkaiensis
Takeda, 1985, and P . belauensis Suzuki & Takeda, 1987, in having a broadly triangular rostrum, somewhat broad
and spinulose or denticulate lateral carapace lobes, and additionally with the latter two species, the laterally ridged
carpi of the ambulatory legs. Porcellanopagurus jacquesi shares with P. japonicus a small, spiniform posterior
carapace lobe; in both P. nihonkaiensis and P. belauensis this lobe is quite blunt. Like P. jacquesi, a postrostral
furrow is present in both P. japonicus and P. belauensis that is lacking in the only known specimen of
P. nihonkaiensis. The presence of a strongly acute, spiniform rostrum and absence of laterally ridged carpi of the
ambulatory legs immediately distinguishes P. japonicus from the other three species. The development, in
P. nihonkaiensis and P. belauensis, of a triangular distal lobe on the rostrum also sets these species apart from
P. jacquesi, where the rostrum terminally is subacute or rounded and slightly depressed. The width of the shield is
appreciably greater in P. belauensis than in the other three species.
In P. nihonkaiensis the ventral margins of the propodi of the ambulatory legs are described as having five
corneous spines, the dactyls seven; P. belauensis is reported to have three corneous spines on the ventrodistal angle
and a row of seven additional spines on the ventral margins of the propodi of the second pereopods, while the
spines on the third pereopods number two distally and five marginally. The dactyls of the second pereopods have
nine spines, the third, 1 1 in this species. Porcellanopagurus jacquesi is intermediate in having one or two corneous
spines on the ventrodistal angles of the propodi and three to six on the ventral margins; the ventral spines of the
dactyls range from eight to 1 1.
Iakeda (1985, figs 1 A-C) illustrated, but did not discuss the tergites of the sixth abdominal somite and
uropods in P. japonicus, P. nihonkaiensis and P. truncatifrons. For P. japonicus the sixth tergite is represented by
a rounded anterior lobe with shallow, incomplete median furrow and rectangular posterior lobe with deeper but still
incomplete median furrow. This tergite in P. nihonkaiensis and P. truncatifrons is illustrated as having a triangular
anterior lobe with central median depression; the rectangular posterior lobe has a well developed and nearly
complete longitudinal groove. As described above and illustrated in Fig. 9a, P. jacquesi has two subequal
rectangular lobes, each with a longitudinal median furrow, incomplete only on the posterior lobe. Like P. jacquesi,
the uropods of P. japonicus show only a small protuberance posteriorly from the protopod of the right uropod. In
P. nihonkaiensis the protopods of both uropods show a well developed posterior protuberance, and in
PAGUR1DAE FROM THE KARUBAR EXPEDITION
469
P. truncatifrons an even more prominent spiniform protuberance. Depicted by SUZUKI and TAKEDA (1987,
fig. 3p), but not described is a similar strong spine on the protopod of each uropod of P. belauensis ; the sixth
abdominal tergite in this species is clearly divided into four distinct, well separated lobes.
Balss (1913) did not describe the telson of P. japonicus but his figure (fig. 40) shows a reduced and
subtriangular structure. As previously mentioned, TAKEDA (1985, fig. 1B-C) illustrates P. rtihonkaiensis and
P. truncatifrons without telsons. His specimen of P. japonicus is depicted with an elongate telson, lacking both
transverse suture and median cleft. The telson of P. belauensis, as illustrated by SUZUKI and TAKEDA (1987), has
the anterior and posterior lobes divided by a complete transverse suture, and the posterior lobes by a longitudinal
median groove over their entire length. Porcellanopagurus jacquesi has a well developed telson with transverse
suture weakly marked and with a small median cleft separating the posterior lobes.
Rather abundant setation was illustrated by BALSS (1913, fig. 40) for P. japonicus. Both in the description and
figures (SUZUKI & TAKEDA, 1987) P. belauensis is characterized as having abundant setation on the carapace and
all appendages. In contrast, setation was described by TAKEDA (1985) as being sparse in P. nihonkaiensis. Very
sparse setation is also characteristic of P. jacquesi.
Remarks. — Although the specimen selected as the holotype is the smaller of the two, it is the only
specimen with all appendages still attached. The carapaces of both specimens were damaged in collection; however,
that of the paratype had been severed in such a way that it has been possible to reconstruct it accurately (Fig. 9a).
The abdomen of this specimen is in excellent condition, whereas that of the holotype is badly shriveled and the
telson is missing.
WHITELEGGE (1900), in his original description of Porcellanopagurus tridentatus, described the coxae of the
fifth pereopods as having a "tubular prolongation, directed inwards and downwards, and their margins are fringed
with long setae". His statement could apply equally well to the coxae of P. jacquesi, although there is no doubt
that the two are distinct taxa. When discussing the relationship of Solitariopagurus with Porcellanopagurus,
TURKAY (1986), called attention to WHITELEGGE’s (1900) report, but commented that he could detect no sexual
tubes in the male syntype of this species that he examined. Close inspection of the coxae of both males of
P. jacquesi similarly does not support the supposition that these elongations represent sexual tubes.
Genus ALAINOPAG UR OIDES nov.
DIAGNOSIS. — Eleven pairs of phyllobranchiate gills. Anterior carapace vaulted and generally well calcified,
with anterolateral regions slightly depressed. Linea transversalis as calcified rod, posterior carapace membraneous or
with slight calcification. Ocular acicles simple. Antennal peduncle with supernumerary segmentation. Maxillule
with external endopodal lobe obsolete or absent. Third maxilliped with crista dentata of ischium (Fig. 10a)
somewhat reduced, but with 1 accessory tooth. Sternite of third maxillipeds with anterior margin rounded on either
side of median concavity. Sternite of second pereopods subdivided into broad lateral lobes by deep longitudinal
median groove. Sternite of third pereopods (Fig. 10b) with narrow, transverse anterior lobe and broad posterior lobe
divided by deep median groove. Fourth pereopods weakly semichelate, propodal rasp rudimentary; with prominent
tubular preungual process (Fig. 10c) at base of claw.
Abdomen reduced; tergal plate of first somite chitinous; tergal plates of second through fifth somites
sometimes very faintly delineated; tergite of sixth somite (Fig. lOd) weakly calcified, subdivided into narrow to
moderately broad anterior lobe, and posterior pair of broad plates separated by distinct median groove. Uropods
generally symmetrical. Telson with transverse suture; posterior lobes usually separated by shallow median cleft.
Males with moderately long and stout sexual tube on coxa of right fifth pereopod (Fig. lOe), left often with
very short tube; no paired or unpaired pleopods. Female with paired gonopores; no paired pleopods; unpaired left
biramous pleopods on abdominal somites 2 to 4 (Fig. lOf).
Type Species. — Alainopaguroides lemaitrei, sp. nov. Gender masculine.
Etymology. — This genus is named for Alain CROSNIER, marine biologist of ORSTOM, in recognition of
his many contributions to our knowledge of the decapod fauna of the Indo-Pacific.

p. a. McLaughlin
AFFINITIES. — Although Alainopaguroides shares a number of important characters with several other genera,
no precise phylogenetic relationships can yet be determined. In reduction of the abdomen, total absence of paired or
unpaired pleopods in males and lack of the left fifth pleopod in females, Alainopaguroides, Porcellanopagurus,
Ostraconotus A. Milne Edwards, 1 880, Solitariopagurus, and Alainopagurus conceivably might all be considered
sister taxa. However, 11 pairs of phyllobranchiate gills are common to species of Porcellanopagurus,
Alainopagurus and Alainopaguroides, while Ostraconotus and Solitariopagurus species have only 10. The rostrum
is very strongly produced and broadly triangular in species of Solitariopagurus and some species of
Porcellanopagurus, developed as a prominent slender spiniform projection in Alainopagurus, but broad and bluntly
truncated in other species of Porcellanopagurus or upturned in Ostraconotus and Alainopaguroides. The lateral
regions of the anterior carapace are drawn out into spinose lobes in Porcellanopagurus and Solitariopagurus, or
simply globular in Alainopagurus, whereas only spinulose margins are seen in Ostraconotus, and simply rounded
margins in Alainopaguroides. Varying areas of weak calcification are observed on the posterior carapaces of species
of four of the genera; yet, only in Ostraconotus is there nearly complete calcification of the posterior carapace. The
second through fifth abdominal tergites of Solitariopagurus and Alainopagurus are chitinized or calcified to some
extent, while those of the other three genera are only faintly indicated.
Quite different specializations in the fourth pereopods are seen among the five genera. With the one exception
previously mentioned, in Porcellanopagurus species the fourth pereopod is semichelate; the propodal rasp consists
of a single row of very small spinules. The semichelae of Alainopagurus and Alainopaguroides are similar in
having the ventrodistal portion of the propodus very weakly produced; the propodal rasp consists of a single row of
small spines in Alainopagurus, but only two or three distal scales or corneous spines in Alainopaguroides. The
fourth pereopods of Solitariopagurus species are distinctly subchelate, allowing the dactyl to articulate against the
ventral margin of the propodus; the propodal rasp consists of a row of bulbous scales. Major structural differences
and sexual dimorphism are seen in the fourth pereopods of Ostraconotus. Females of the only known species,
Ostraconotus spatulipes A. Milne Edwards, 1880, have an extremely paddle-shaped propodus and simple
articulating dactyl; the propodus of the male is approximately half the breadth of the female, but the dactyl is
similar. Rather typical pagurid type, minutely chelate, fifth pereopods are found in Ostraconotus,
Porcellanopagurus and Alainopaguroides, but subchelate in Solitariopagurus and in Alainopagurus. Species of
Porcellanopagurus, Alainopagurus and one species of Solitariopagurus are known to utilize bivalve shells as their
microhabitat; nothing is known for the others.
Extensions of the vas deferens as sexual tubes are present in all of the aforementioned genera except
Porcellanopagurus. Species of this latter genus occasionally show a posterior elongation of one or both coxae, but
no tubular structure arises from a gonopore. In contrast, males of Alainopagurus and Solitariopagurus have short,
equal or unequal sexual tubes produced from the gonopores of both fifth pereopods. Males of Ostraconotus have a
single right sexual tube, whereas Alainopaguroides has an elongate right sexual tube and usually a very short left,
although it may only resemble a small protuberance in smaller specimens. While females of all five genera have
no paired pleopods and only left unpaired egg-bearing pleopods (left second through fourth), paired gonopores occur
in Porcellanopagurus, Ostraconotus, and Alainopaguroides, but only single left gonopores are found in females of
Solitariopagurus and Alainopagurus.
Until Turkay's (1986) account of Solitariopagurus, Ostraconotus and Porcellanopagurus had been considered
the prime examples of carcinization in the Paguridae (e.g., BORRADAILE, 1916; Wolff. 1961). The recent
discovery of Alainopagurus, and now Alainopaguroides, brings to five the candidates for this distinction. As may
be seen from the foregoing brief review of major characters in these genera, no clearly defined evolutionary
pathway can yet be observed.

COLOR. — Unknown.
Habitat. — One specimen found occupying gastropod shell well covered by anemone.
Distribution. — Presently known only from the Kai and Tanimbar Islands, Indonesia; 210 - 502 m.
Etymology. — This species is named for Dr. Rafael Lemaitre, National Museum of Natural History,
Smithsonian Institution in recognition of his continuing contributions to pagurid systematics.
AFFINITIES. — The generic discussion previously presented pertains directly to A. lemaitrei as it is the only
known representative of the genus. However, the elongation of the right sexual tube and its right-to-left direction
over the dorsal part of the abdomen in this genus is more reminiscent of sexual tube development in Catapagurus
than in any of the other previously discussed genera. Alainopaguroides also shares with Catapagurus such charac¬
ters as short and stout ocular peduncles with dilated corneae and moderate to long ocular acicles, although these are
also seen in Ostraconotus spatulipes. The general structure and armature of the chelipeds and ambulatory legs, as
well as the specialized preungual process on the fourth pereopod, also resemble those of Catapagurus species.
REMARKS. — Contrary to the typical relationship of shield length to animal size in the majority of pagurids,
this is not the case in A. lemaitrei. In this species, there is a marked increase in shield breadth in proportion to
length with increased animal size. However, as width increases, so does the general convexity of the shield,
making accurate linear width measurements impossible.

As indicated in the description, there is a tendency in some males for the length of the left cheliped to
noticeably exceed that of the right; however, this phenomenon does not appear to necessarily be a function of size.
In the holotype, which was the largest male examined, the left cheliped was shorter than the right, as it was in all
females. In two of the slightly smaller males, the left cheliped overreached the right by a quarter to a half the
length of the left dactyl.

2 spines on ventrodistal margins and 2 or 3 widely-spaced and smaller spinules on ventral surface. Carpi each with
minute spinule on dorsodistal margin. Sternite of third pereopods with subsemicircular unarmed anterior lobe
(Fig. Ilf).
Telson (Fig. 1 1 g) with terminal margins of posterior lobes horizontal to slightly oblique, armed with 4 and
7 small spines, lateral margins with serrate marginal plate.
Color (in preservative). — Only remaining color: left cheliped faint orange with tips of dactyl and fixed finger
white, distal margin of carpus darker orange and light orange band distally on merus.
Habitat. — Unknown.
Distribution. — Known only from one locality in the Kai Islands, Indonesia; 205-212 m.
Remarks. — This specimen has been referred to Anapagrides because of its considerable similarity to ,4. reesei
(McLaughlin, 1986), a species known only from subtidal Pocillopora rubble at Kahe Point, Oahu, in the Hawaiian
Islands. Anapagrides reesei , like the Karubar specimen, is very small, with females ovigerous in very much the
same size range (1.2- 1.4 mm). The armature of the left cheliped is nearly identical in the two species, as is that of
the right chela. Like A. reesei, the anterior lobe of the sternite of the KARUBAR specimen is subsemicircular; the
terminal margins of the telsons of both taxa are slightly oblique and armed with a few spines, the lateral margins
carry a serrate chitinous plate. The latter species differs from the Hawaiian taxon in having slightly longer antennal
peduncles, a row of tiny spines on the dorsolateral margin of the carpus of the right cheliped, and minute spinules
on the dorsodistal margins of each of the ambulatory legs.
There is also an affinity, albeit less striking, between the Karubar specimen and A. facetus (Melin, 1939),
particularly in the relative proportions of the cephalic appendages; however the rostrum of A facetus is stronger
than the lateral projections. In A. facetus at least the dactyl of the third left pereopod has a row of corneous spines
on the mesial face (cf. McLaughlin & Sandberg, 1995). Similar armature of the mesial faces of the dactyls of
the third pereopods can be observed in the Karubar specimen. Differences in the female of /l. facetus include
having a pair of strong spines on the dorsal surface of the carpus of the right cheliped, whereas the Karubar
specimen has a lateral row of small spines. The anterior lobe of the telson of A. facetus is subrectangular.
In the absence of male characters, a female specimen having a single left gonopore and no paired first pleopods
modified as gonopods also conceivably might represent a species of Trichopagurus de Saint Laurent, 1970b or
Pagurixus. However, the gills are intermediate in the monotypic Trichopagurus, but unquestionably phyllobranch
in the Karubar specimen. The occurrence of an unpaired left gonopore in species of Pagurixus is variable; but in
all species, the rostrum is usually well developed and the lateral projections weak or obsolete. A reversed condition
is seen in the Karubar specimen. Additionally, all of the 13 species of Pagurixus now recognized (cf. Morgan,
1993; Komai & Asakura, 1995) are described as having a subrectangular or subquadrate anterior lobe developed
on the sternite of the third pereopods.
Tan asopagurus rostrodenticulatus gen. nov., sp. nov., and 1 Anapagrides sp. also share common characters such
as the armature of the chelipeds and spination of the ambulatory legs. Females of the two taxa are readily
distinguished, T. rostrodenticulatus by the presence of paired gonopores and first pleopods, ? Anapagrides sp. by a
single left gonopore and the absence of paired first pleopods. If assignment of the Karubar specimen to
Anapagrides is correct, males would correspondingly be easily distinguished by sexual tube development, i.e., left
in T. rostrodenticulatus, right in Anapagrides sp. Although these two taxa occurred sympatrically at Stn DW 18,
the intermediate type gills of the two presumably juvenile male specimens assigned to T. rostrodenticulatus
immediately distinguished them from l Anapagrides sp., despite their lack of sexual tubes and denticulate rostra.

DIAGNOSIS. — Eleven pairs of trichobranchiate gills. Rostrum narrowly triangular. Ocular acicles simple or
multifid. Antennal peduncle with supernumerary segmentation. Maxillule with external lobe of endopod somewhat
produced, not recurved. Crista dentata of ischium of third maxilliped without accessory tooth. Dactyls of
ambulatory legs with armed ventral margins. Chelipeds unequal or subequal, right appreciably stouter. Fourth
pereopods semichelate; with single row of scales in propodal rasp. Sternite of fifth pereopods developed as single
small subovate or subquadrate lobe.
Coxa of left fifth pereopod in males (Fig. 3c) with moderately long or long, often weakly spiraled, sexual tube
provided with sparse terminal tuft of stiff setae (Fig. 3d); right fifth coxa with gonopore, occasionally vas deferens
slightly produced, but not developed as distinct sexual tube; 3 uniramous or unequally biramous unpaired left
pleopods. Females with paired gonopores; no paired pleopods, unpaired left pleopods on somites 2 to 5.
Telson with transverse suture only weakly indicated; terminal margins oblique.
Remarks. — Laurentia McLaughlin & Haig, 1996 has proved to be a junior homonym of Laurentia Ragonot,
1888, a lepidopteran genus (cf. Fletcher & Nye, 1984: 80), and as such must be replaced. McLaughlin
and HAIG chose the name Laurentia in recognition of the work of M. DE SAINT LAURENT. In propos¬
ing the replacement name Turleania, an anagram (from Laurentia), the dedication remains unchanged; gender
feminine.
All four originally described species, type species T. albatrossae McLaughlin & Haig, 1966, T. balli
McLaughlin & Haig, 1996, T. sibogae McLaughlin & Haig, 1996, and T. senticosa McLaughlin & Haig, 1996,
were collected in Indonesian waters; however, only T. senticosa is represented in the KARUBAR material.
The generic diagnosis has been broadened to include a fifth species. Turleania multispina sp. nov. is the first

cheliped with faint spot of orange near the tip of fixed finger and larger patch proximally. Left cheliped with band
ol light orange proximally on dorsal surfaces of dactyl and fixed finger. Band of light orange present distally on
dactyls of ambulatory legs.
Habitat. — Unknown.
Distribution. — Seram, Kai and Tanimbar Islands, Indonesia; 85-186 m.
Affinities. — McLaughlin and Haig (1996), discussed the similarities between T. senticosa and
T albalrossae- Turleania multispina similarly resembles T. senticosa in having the dorsal surfaces of the chelae
armed with small spines or spinules. The other species, T. balli and T. sibogae both have unarmed chelae. The
specimens of T. senticosa collected during the Karubar expedition all have the spines of the dorsomesial region
of the palm of the right cheliped more strongly developed than in the type series. With that exception, two males
r°m lhe Kai Islands agree exceptionally well with the holotype; the specimens from Tanimbar Islands do not
exhibit the hiatus between the dactyl and fixed finger.

Remarks. — Antennal flagella were missing from the type specimens described by McLaughlin and Haig
(1996). They have been included in the diagnosis presented based upon the present material. The Karubar speci¬
mens of T. senticosa , while agreeing with the type material from Scram Island in most characters, do exhibit some
variations not noted by McLaughlin and Haig. As previously indicated not all of the present specimens have a
hiatus between the dactyl and fixed finger of the right cheliped; in one specimen, the spine on the ventromesial
distal angle of the merus is absent. Similarly, the left cheliped of one specimen has one rather than two spines on
the ventrolateral distal angle. The most noteworthy variation is seen in the telson. In all of present specimens the
posterior lobes are clearly asymmetrical; the oblique margins are armed with two or three spines (Figs 1 Ib-d).

Coxae of fifth pereopods in males (Fig. 13b) symmetrical; right, left, or both with short sexual tube;
3 unequally biramous unpaired left pleopods. Females with paired gonopores; paired first pleopods modified as
gonopods, unpaired left pleopods on somites 2 to 5.
Telson with transverse suture; posterior lobes separated by distinct median cleft; terminal margins rounded;
lateral margins, at least left, with corneous plate.
ETYMOLOGY. — The genus is named for Michele de Saint Laurent, who first recognized that
Henderson's (1888) Pagurodes consisted of three distinct taxa.
Type Species. — Pagurodes limatulus Henderson, 1888. Gender masculine.
Remarks. — Henderson (1888) described the genus Pagurodes for three superficially similar Indo-Pacific
species collected during the "Challenger" expedition. Pagurodes inarmatus was based upon eight syntypes;
P. piliferus and P. limatulus were each represented by single specimens, although a second small, poorly preserved
specimen was "doubtfully" referred to P. piliferus. HENDERSON indicated that while the trichobranchiate gills,
presumably, possessed by all three species suggested a relationship with Parapagurus Smith, 1879, Pagurodes was
distinct because males had sexual tubes rather than paired first and second pleopods, modified as gonopods.
When DE Saint Laurent (1969) erected the genus Acanthopagurus de Saint Laurent, she expressed her belief
that HENDERSON'S (1888) species of Pagurodes actually represented three distinct genera. She designated
Pagurodes inarmatus as the type species of HENDERSON'S taxon, thus restricting Pagurodes, and indicated that
P. piliferus and P. limatulus would be separated in a later publication. That separation was never formalized.
Having now reexamined five of HENDERSON'S syntypes of P. inarmatus, including the male specimen from
"Challenger" station 168 upon which he based his description, as well as all "syntypes" of the two other species, it
is clear that DE Saint Laurent (1969) was correct in her evaluation. Pagurodes, as defined by the characters of
the examined syntypes of P. inarmatus, is a plainly identifiable taxon. Although P. inarmatus is not represented in
the Karubar material, it is in the interest of stability in nomenclature that Henderson's (1888) described male
(NHM 88.33) (Figs 15d, 35b-e) be designated as the lectotype of P. inarmatus.
Alcock (1905b) redescribed P. limatulus, pointing out that his female specimen(s) possessed paired first
pleopods modified as gonopods; however, he did not propose a distinct genus for this species. Instead he simply
noted in his generic description that paired first pleopods were present in females of at least one species. When
BouviER (1922) assigned two new abyssal Atlantic species to Pagurodes sensu lato, he remarked that since his
species were both represented by only single specimens, he could not be sure that all characters of the genus were
present. As previously indicated, DE SAINT LAURENT (1969) noted that neither P. limatulus nor P. piliferus were
congeners of P. inarmatus. Of P. limatulus she commented that this species would be assigned to a new taxon,
together with BOUVIER'S (1922) species, Pagurodes richardi Bouvier and Pagurodes atlanticus Bouvier. That
publication was never completed. In his comprehensive treatment of Atlantic pagurids, INGLE (1993) retained
P. richardi and P. atlanticus in Pagurodes (sensu Bouvier, 1922), noting that until DE Saint Laurent's (1969)
opinions could be reevaluated through a thorough study of Henderson's (1888) Indo-Pacific species, the generic
placement of the Atlantic species was uncertain.
McLaughlin (1988) considered the possible relationship of "Pagurodes" limatulus with the Atlantic
Pagurus" piercei Wass, 1963, unlikely, when she proposed the genus Goreopagurus for the latter taxon. The
recent discovery of a second species of Goreopagurus from the eastern Pacific (McLaughlin & Haig, 1995)
confirms the distinctive characters of this genus that set it apart from Henderson's (1888) species.
Pagurodes limatulus is herein reassigned to Michelopagurus gen. nov. as its type species; Pagurodes richardi and
Pagurodes atlanticus are also, provisionally, reassigned to this genus.

sternite of the third pereopods. The two Indo-Pacific species are separated by the shorter and more stout ocular
peduncles of M. limatulus and its more elongate and slender chelipeds.
Remarks. — In addition to the species of Henderson (1888) and Bouvier (1922) now assigned to
Michelopagurus , de Saint Laurent (1969) indicated that she had seen three undescribed species among the
Albatross and Siboga collections. As indicated above, one additional species assignable to this genus is present
in the Karubar material, but it is unknown whether it is one of the three seen by DE Saint Laurent.

Color. — Unknown.
Habitat. — Unknown.
Distribution. — Kai Islands, Indonesia; 264-425 m.
ETYMOLOGY. — Dedicated to Dr Fenner A. CHACE, Zoologist Emeritus of the Division of Crustacea,
National Museum of Natural History, Smithsonian Institution, who, during a continuing long and active career
has contributed so much to decapod systematics.
Affinities. — As previously noted, Michelopagurus chacei bears a considerable resemblance to M. limatulus,
particularly in the structure of the anterior lobe of the sternite of the third pereopods and development of the telson
armature. In addition to the distinguishing characters of M. limatulus mentioned above, the shield of M. chacei
tends to be slightly broader and the antennular flagella longer than seen in M. limatulus ; however, these characters
may well be subject to intraspecific variation when large samples are available for examination. The ambulatory
legs appear to provide the best characters for separating the two species. A row of spinules or tubercles is present
on the ventral margins of the meri of the second pereopods of M. limatulus, and the ventral margins of the dactyls
are provided with 11 to 19 corneous spines. In M. chacei , the meri of the second pereopods have only one or two
distal spinules on the ventral margins; the ventral margins of the dactyls are armed with nine to 1 1 corneous
spines.
Genus PSEUDOPAGURODES nov.
Pagurodes Henderson, 1888: 94 (in part). — ALCOCK, 1901: 224; 1905b: 106 (in part). — Gordan, 1956: 324 (in part;
lit.). — de Saint Laurent, 1969: 740 (in part).
DIAGNOSIS. — Eleven pairs of intermediate type gills. Rostrum reduced and rounded. Ocular acicles small,
widely separated. Maxillule with external lobe of endopod well developed, not recurved. Third maxilliped with well
developed crista dentata and 1 accessory tooth. Chelipeds subequal. Dactyls of ambulatory legs without corneous
spinules on ventral margins. Fourth pereopods semichelate; propodal rasp with single row of scales; no preungual
process at base of dactylar claw. Fifth pereopods chelate.
Male unknown. Female with paired gonopores, no paired pleopods on first abdominal somite, and 4 unequally
biramous left pleopods on somites 2 to 5.
Asymmetrical uropods. Telson with transverse suture, subtriangular posterior lobes separated by median cleft.
ETYMOLOGY. — From the Greek pseudes meaning false, and pagouros meaning crab, reflecting the deceptive
similarities between this genus and Pagurodes sensu stricto.
Type Species. — Pagurodes piliferus Henderson, 1888. Gender masculine.
REMARKS. — With the restriction of Pagurodes to taxa exhibiting the characters manifest by P. inarmatus and
the establishment of Michelopagurus gen. nov. for P. limatulus , Pagurodes piliferus is left in a systematic limbo.
The damaged male specimen from the Arafura Sea that HENDERSON (1888) doubtfully assigned to P. piliferus was
subsequently redetermined to be Pagurus compressipes Miers, 1884, by M. de Saint Laurent (unpublished).
I concur with her identification. The remaining, and true type specimen of Pagurodes piliferus (NHM 88.33) is a
female (Figs 13e-f, 37a-b) with intermediate gills, thus clearly not allied to Pagurodes sensu stricto, nor to

Michelopagurus gen. nov. In gill structure Pseudopagurodes approaches Tarrasopagurus gen. nov., but differs from
that genus in having subcqual, elongate chelipeds and ambulatory legs, while lacking paired first pleopods. No
specimens of Pseudopagurodes were found during the KARUBAR expedition.
Genus ICELOPAGURUS nov.
Diagnosis. — Eleven pairs of phyllobranchiate gills. Rostrum triangular. Ocular acicles triangular, elongate.
Antennal peduncle with supernumerary segmentation. Maxillule (Fig. 15a) with external lobe of endopod
rudimentary or vestigial. Crista dentata of third maxilliped somewhat reduced, but with accessory tooth. Chelipeds
elongate, subequal, right stouter. Sternal plate of third pereopods broad, with weak longitudinal groove. Fourth
pereopods semichelate; with single row of spiniform scales in propodal rasp; dactyl with tubular preungual process
(Fig. 15b).
Coxae of fifth pereopods in males (Fig. 15c) symmetrical, right with stout, relatively short sexual tube directed
posteriorly and externally, left usually with very short sexual tube; 3 unequally biramous unpaired left pleopods.
Females with paired gonopores; without paired first pleopods modified as gonopods, unpaired left pleopods on
somites 2 to 5.
Telson with transverse suture; rounded posterior lobes separated by distinct median cleft with nearly
perpendicular margins, terminal margins armed; lateral margins with very narrow chitinous plate.
Type Species. — Icelopagurus crosnieri sp. nov. Gender masculine.
Etymology. — From the Greek ikelos meaning like or resembling, and pagouros meaning crab, and referring
to the similarities shared with another pagurid genus, namely, Catapagurus.
Remarks. — As indicated in the derivation ol its name, Icelopagurus is superficially very similar to
Catapagurus. Both genera are characterized by unusually elongate ocular acicles, rudimentary or vestigial external
endopodal lobe on the maxillule, more or less reduced crista dentata with one accessory tooth, distinctive tubular
preungual process on the dactyl of the fourth pereopod, well developed right male sexual tube, and females lacking
specialized secondary sexual characters. However, Icelopagurus is readily separated from Catapagurus by the
shortness of the male sexual tube that does not curve up over the dorsal surface of the body and by the very
distinctive development of the telson.
Icelopagurus is also ostensibly quite similar to Pagurodes sensu stricto. As presently known, both taxa are
monotypic, and their type species share such immediately observable characters as elongate chelipeds and
ambulatory legs, well calcified shields that tend to be somewhat vaulted, long antennal acicles, triangular rostra,
very short, stout ocular peduncles provided with low protuberances and tufts of setae, and males with a short sexual
tube arising from the coxa of the right fifth pereopod and an even shorter tube from the left (Figs 15c-d). However,
upon closer inspection, the ocular acicles of Pagurodes inarmatus (Fig. 35b) are short, reaching only to the basal
portion of the peduncles; the external lobe of the maxillulary endopod is completely absent; the gills are
trichobranchiate; the dactyl of the fourth pereopod lacks a preungual process; and the posterior lobes of the telson
are acutely subtriangular with strongly oblique terminal margins armed with 3 or 4 small spines. In contrast,
/. crosnieri sp. nov. has very long ocular acicles (fig. 38b), reaching to or beyond the bases of the corneae; the
external lobe of the maxillulary endopod is vestigial; the gills are phyllobranchiate; the dactyl of the fourth
pereopod is provided with a large tubular preungual process; and the posterior lobes of the telson are broadly
rounded, with convex terminal margins armed with 4 or 5 widely-spaced long corneous spines.

PAGURIDAE FROM THE KARUBAR EXPEDITION
491
Distribution. — Tanimbar Islands, Indonesia; 884-891 m.
Etymology. — Dedicated to Alain Crosnier, marine biologist of ORSTOM, who made the collection
available for study.
AFFINITIES. — Icelopagurus crosnieri most closely resembles Catapagurus oculocrassus sp. nov. in overall
morphology, but is immediately distinguished from that species by the major differences in the telsons of the
two species. As noted in the remarks for the genus, /. crosnieri also shares several general characters with
Pagurodes inarmatus , but differs significantly from the latter species in the spination of the chelipeds, as well as
in the numerous characters cited above.
Genus TARRASOPAGURUS nov.
DIAGNOSIS. — Eleven pairs of intermediate gills. Rostrum obtusely triangular or broadly rounded, with 1 or
more marginal spinules. Ocular acicles triangular. Antennal peduncle with supernumerary segmentation. Maxillule
(Fig. 16a) with external lobe of endopod moderately well developed, not recurved. Crista dentata well developed,
1 accessory tooth. Chelipeds markedly unequal, right considerably longer and stronger. Fourth pereopods
semichelate; with single row of scales in propodal rasp.
Coxae of fifth pereopods in males (Fig. 16b) generally symmetrical, left with short sexual tube directed
anteriorly or posteriorly, right sometimes also with short tube developed, sometimes with vas deferens only
slightly protruded; 3 unpaired, unequally biramous pleopods. Females with paired gonopores; paired first pleopods
modified as gonopods, unpaired left pleopods on somites 2 to 5.
Telson with transverse suture; posterior lobes subequal, terminal margins oblique.
ETYMOLOGY. — From the Greek tarraso meaning confused, and pagouros meaning crab, and referring to the
characters of this genus shared with several other pagurid genera.
Type Species. — Tarrasopagurus rostrodenticulatus sp. nov. Gender masculine.
REMARKS. — As its etymology indicates, Tarrasopagurus shares a number of characters with several other
pagurid genera. In having intermediate type gills (Fig. 16c), markedly unequal chelipeds and relatively short
ambulatory legs, it agrees with Cestopagurus as redefined by DE Saint Laurent (1968c). It is distinguished from
species of Cestopagurus by the presence in the latter genus of an elongate right sexual tube, which is directed from
right to left across the ventral part of the body and a very short left sexual tube that may or may not be developed.
Intermediate gills are also a character that Tarrasopagurus shares with Pseudopagurodes, but females of that genus
lack the paired first pleopods found in Tarrasopagurus species; males of Pseudopagurus are not presently known.
Short paired male sexual tubes is a character that Tarrasopagurus shares with Parapagurodes McLaughlin & Haig,
1973; but again, females of this latter genus lack paired first pleopods modified as gonopods. A character that
Tarrasopagurus shares with Michelopagurus nov. gen., in addition to short or very short male sexual tubes, is
paired female first pleopods. However, the gills in Michelopagurus are clearly trichobranchiate in structure,
whereas those of Tarrasopagurus are intermediate. The chelipeds in this genus are grossly unequal; the ambulatory
legs are relatively short, overreaching the outstretched right cheliped little if at all. In contrast, the chelipeds of
Michelopagurus species are elongate and subequal; the ambulatory legs are long and slender, and considerably
overreach the outstretched chelipeds.

ventrolateral margin, ventromesial margin with 3 or 4 widely-spaced small spines or spinules. Ischium unarmed.
Ambulatory legs (Figs 1 6i-j) similar from left to right. Dactyls equal to or only very slightly longer than
propodi; very slightly curved, not twisted; dorsal surfaces each with row of sparse tufts of setae; ventral margins
each with row of 6 to 9 strong corneous spines. Propodi with tufts of short setae on dorsal surfaces; ventrodistal
angles each with corneous spine, ventral surfaces each with row of widely-spaced corneous spinules. Carpi each
with tiny spinule at dorsodistal angle, dorsal surfaces with few tufts of setae. Meri and ischia unarmed. Sternite of
3rd pereopods with large semicircular anterior lobe, unarmed but with marginal row of setae. Fourth pereopod with
moderately elongate dactyl (Fig. 16k). Fifth pereopods chelate.
Coxae of fifth pereopods in males (Fig. 16b) with short left and frequently also short right sexual tube.
Telson (Fig. 161) with prominent transverse suture; posterior lobes with chitinous lateral margins, median cleft
prominent; terminal margins oblique, with 4 or 5 spines, largest usually at outer angle.
COLOR (in preservative). — Ocular peduncles with orange tint, darker basally. Ambulatory legs with distal
halves of dactyls and propodi white, proximal halves orange; carpi each with longitudinal orange stripe dorsally and
laterally; meri each with faint orange band on lateral face distally.
Habitat. — Gastropod shells.
Distribution. — Kai Islands, Indonesia; 205-425 m.
Etymology. — The specific epithet reflects the unusual denticulate rostral margin of this species.
Affinities. — At first glance, the small size and general shape and armature of the chelipeds and ambulatory
legs of Tarrasopagurus rostrodenticulatus might suggest a relationship with species of Pagurixus Melin, 1939.
However, where males of Pagurixus species have the right gonopore masked by a mesially directed tuft of stiff
setae, males of Tarrasopagurus have developed sexual tubes, albeit quite short; females possess paired first
pleopods modified as gonopods. Females of Pagurixus have no special sexual modifications, although not
uncommonly only one gonopore develops. The denticulate rostral margin of T. rostrodenticulatus immediately sets
it apart from all other known species.
Remarks. — Two very small specimens (0.8, 1.0 mm) (POLIPI) from Stn DW 18, appeared to be juvenile
males ot this species, but neither had either sexual tube developed, nor could any denticulations be seen on the
rounded rostra. Neither are considered paratypes. Within the size range of 1.0 to 1.5 mm (shield length),
denticulations on the rostral margin are very tiny and difficult to observe; however, with increased animal size
these denticulations become quite obvious.

Males with right sexual tube orientated toward exterior then recurved over anterior part of abdomen; 2 (pleopods
3 and 4) or 3 (pleopods 3-5) unpaired, usually uniramous pleopods. Females with paired gonopores; without paired
first pleopods modified as gonopods, with pleopods 2 to 4 biramous, pleopod 5 similarly present or absent.
Telson with transverse suture; posterior lobes subtriangular; terminal margins oblique.
Remarks. — In her revision of Catapaguroides and Cestopagurus, DE Saint Laurent (1968a) transferred
three species from Catapagurus to other existing genera, including C. vallatus Melin, 1939, to Nematppagurus.
However, she did not consider Catapagurus australis Henderson, 1888. Despite HENDERSON'S correct diagnosis of
the generic characters of Catapagurus, a recent rexamination of the syntypes of C. australis (NHM 1888.33) have
shown that the structure of the sexual tubes and the weak development of the ocular acicles provide convincing
evidence that this species too should have been assigned to Nematopagurus.
Even with the transfer of the three species aforementioned from Catapagurus, Forest and DE Saint Laurent
(1968) and de Saint Laurent (1970a) indicated that the genus still included about ten Indo-Pacific species,
of which several remained to be described. It is unfortunate that the revision promised by de Saint Laurent
(1970a) was never completed. Not only there are serious inconsistencies in the diagnoses that have been presented
by several authors cited in the above synonymy, but major problems in species interpretations prevail as well,
which are beyond the scope of the KARUBAR study. HAIG and BALL (1988) reported the occurrence of a
species they believed to represent Catapagurus ensifer Henderson, 1893, and a second "probably ... undescribed"
species from the Maluku area, noting that the lack of an up-to-date revision of the genus made identification
difficult. The new species described herein are assigned to Catapagurus as defined by Forest and DE Saint
Laurent (1968) and DE Saint Laurent (1970a), until such time as a thorough review of the genus can be
completed.

COLOR (in preservative). — Some specimens in alcohol for four years retain an orange tint on chelipeds,
particularly carpi and meri.
HABITAT. — Gastropod shells frequently covered by bryozoans.
Distribution. — Known only from the Kai and Tanimbar Islands, Indonesia; 466-809 m.
ETYMOLOGY. — From the Latin oculus meaning eye, and crassus meaning stout, indicating the stout ocular
peduncles characteristic of this species.
Affinities. — At first glance, C. oculocrassus bears a more striking similarity to Icelopagurus crosnieri than
to other species of Catapagurus. Both C. oculocrassus and I. crosnieri have noticeably setose shields, very short,
stout ocular peduncles, long and moderately broad ocular acicles, elongate antennular peduncles, relatively slender
subequal chelipeds, comparable tubular preungual process at the base of the claw of the dactyl of the fourth
pereopod, and a right male sexual tube. Differences of cheliped armature are species distinctive, but it is the
subtriangular, relatively weakly armed posterior telsonal lobes of C. oculocrassus that provides the most
convincing generic distinction.
The species of Catapagurus described herein are morphologically very closely allied, in that none have the
blade-like ambulatory dactyls seen in Catapagurus ensifer and the figured, but unnamed species reported by Haig
and Ball (1988) from the Banda and Arafura regions of Indonesia. Catapagurus oculocrassus is most reliably
distinguished from the following new species by the posterior lobes of the telson which have oblique terminal
margins armed with one to four small spines. In all of the other known species, including C. ensifer and Haig and
Ball's species, the perpendicular terminal margins are unarmed or provided only with very short stiff bristles; the
posterior lobes are separated by a very broad and deep median cleft. Until further study of Catapagurus is
completed, its actual generic limits remain uncertain.

Color. — Unknown.
Habitat. — One specimen occupied a shell of Natica sp.
DISTRIBUTION. — Known from the Kai and Tanimbar Islands, Indonesia; 184-301 m.
ETYMOLOGY. — Named for the Tanimbar Islands of Indonesia.
AFFINITIES. — Catapagurus tanimbarensis and the following new species share many general morphological
attributes, but can be distinguished by the shapes of their telsons, as is the case of other Indo-Pacific species of the
genus (Haig & Ball, 1988). Additionally, neither of the other new species described herein have the mesial faces
of the ambulatory dactyls armed with a ventral row of spines. The shorter antennular peduncles, but longer
antennal acicles distinguish C. tanimbarensis from C. holthuisi sp. nov., while the more strongly dilated corneae
and more slender ocular acicles immediately separate C. tanimbarensis from C. oculocrassus.
Remarks. — Particularly in the holotype, but also to a lesser extent in both paratypes, the setae on the dorsal
margins of the dactyls of the ambulatory legs have been broken off. All that remains to indicate their original
presence is a row of distinct sockets (Fig. 18e).
Two additional ovigerous females, both with shield lengths of 1.5 mm, are assigned to C. tanimbarensis based
on the shape of the telson and armature of the ambulatory dactyls; but because of their conditions, neither are
considered paratypes. The specimen from station DW 50 (POLIPI), collected at a depth of 184 to 186 m, is
missing both third pereopods and chelipeds; the specimen from station DW 03 (MNHN), collected at a depth of
278-301 m, is missing both chelipeds. However, both are included in the geographical and depth distributions of
the species.

COLOR. — Unknown.
Habitat. — One specimen occupied shell of Natica sp.
Distribution. — Known from the Kai and Tanimbar Islands, Indonesia; 223-352 m.
ETYMOLOGY. — This species is dedicated to Dr Lipke B. Holthuis, Nationaal Natuurhistorisch Museum,
Leiden, one of the world’s foremost carcinologists and always a willing advisor.
AFFINITIES. — As previously indicated, C. holthuisi appears quite closely allied to C. tatiimbarensis
particularly in the shape and armature of the chelipeds. The two species are immediately distinguished by the
armature of the ambulatory dactyls; fringed with long setae dorsally and ventromesially in C. holthuisi, but
provided with a mesioventral row of corneous spines in C. tanimbarensis. In the absence of the ambulatory legs,
or in instances where the setae have been broken off, the broad subrectangular median cleft and perpendicularly-
sided terminal margins of the posterior telsonal lobes of C. holthuisi readily separate this species from both
C. tanimbarensis and C. oculocrassus in which the median cleft is V-shaped and the terminal margins oblique.

REMARKS. — As previously mentioned, personal examination of the type specimens of Calapagurus australis
Henderson, 1888, has shown that this species correctly belongs in Nematopagurus and is herein formally
transferred. The specimen upon which HENDERSON (1888) based his description was from "Challenger" station 188
in the Arufura Sea. He stated that the abdomen was missing from that particular specimen, but that the carapace
measured 4.8 mm and the ocular peduncle 2.5 mm. The second specimen, from the reefs at Levuku, Fiji Islands,
was reported to be a "very imperfect specimen”. Catapagurus australis is represented by two syntypes (NHM
1888.33), a male with a shield length of 1.5 mm and carapace length of 2.8 mm, lacking an attached abdomen,
although a somewhat damaged abdomen is present, and a second slightly larger male with attached abdomen, and
shield and carapace lengths of 2.1 and 3.5 mm respectively. The ocular peduncles of neither specimen approach the
2.5 mm given by HENDERSON. The smaller specimen, from "Challenger" station 188 is better preserved, as
Henderson noted, and is accompanied by detached right and left chclipeds and right third pereopod. The syntype
from the Fiji Islands has only a right cheliped and both third pereopods, all detached and poorly calcified. Since
both specimens agree well with HENDERSON'S description, there is no need to designate a lectotype at this time.
With the inclusion of HENDERSON'S taxon, 12 species are currently assigned to Nematopagurus , of which
1 1 are found in the Indo-Pacific region. Three additional new species are described herein. Two others species are
represented in the KARUBAR collection, but their identities both are questionable. One is tentatively assigned to
Nematopagurus indicus Alcock, 1905b; the other most closely resembles N. gardineri Alcock, 1905a, b, but its
conspecificity with this taxon is doubtful. When the host of additional new species of this genus awaiting
description (J. FOREST, personal communication; personal observations) have been fully studied. Nematopagurus
will be one of the most speciose genera in the entire region. In the interim, specimen assignments to known taxa,
particularly of those species exhibiting a median longitudinal row of spines on the dorsal surface of each chela,
must be considered conditional, at best.

Distribution. — Tanimbar Islands, Indonesia; 210-226 m. ?Off Nicobar Islands and Travancore and Cochin
coasts of India; approximately 185-433 m.
Remarks. — Despite the short right sexual tube and lack of a left, the Karubar specimen certainly appears
to belong to Nematopagurus. Whether it is correctly assigned to N. indicus is less certain. At present only
N. indicus and N. gardineri Alcock, 1905a (repeated practically verbatim by ALCOCK, 1905b with the same
illustration), have been described with a median longitudinal row of spines on the palms of the chelae; however,
one new species reported herein is also similarly armed. Neither of the former species is described in much detail,
although ALCOCK (1905a, b) stated that N. gardineri was the more pilose of the two. Except for its pilosity and
armature of the ambulatory legs, the present Karubar specimen agrees more closely with N. indicus than with
N. gardineri. The diagnosis given above is based on the KARUBAR specimen; differences with ALCOCK's
description are discussed below.
The only reports of N. indicus are those of ALCOCK (1905b), BalSS (1912), and KEMP and SEWELL (1912).
Alcock (1905b)'s description was rather general, dealing more with length ratios than specific diagnostic
characters; his figure, if accurate, provides some additional information. Balss (1912) gave no information on his
specimen other than to note that its capture southwest of Great Nicobar in the Nicobar Islands represented an
extension of the range of the species. KEMP and SEWELL (1912) remarked that their male and female specimens
agreed with ALCOCK's (1905b) description and type specimens in all characters except the eyes, which were
distinctly stouter and reached only to the proximal third of the ultimate peduncular segment of the antennule. In
this regard, the KARUBAR specimen agrees more closely with those reported by KEMP and SEWELL (1912).
ALCOCK (1905b) contrasted N. indicus with N. gardineri by "regularly disposed tufts of setae on the hepatic and
gastric regions" of the carapace in the former species and a "smooth carapace" in the latter. In his figure (ALCOCK,
1905b, pi. 12, fig. 4), the carapace setae are shown in two longitudinal rows on the shield. As noted in the
diagnosis, tufts of setae in the single Karubar specimen occur laterally and anteriorly on the shield. The rostrum
of N. indicus was described by ALCOCK as being "very broadly triangular"; it is broadly rounded in the present
specimen. He specified that the ocular peduncles reached beyond the middle of the ultimate segment of the
antennular peduncle. As previously indicated, the ocular peduncles of the Karubar specimen reach only to the
middle; however, minor variations in this length ratio are to be expected. Similarly, the length of the dactyl of the
right cheliped was reported to be shorter than the palm in the Indian specimens, whereas the ratio would be
approximately 1 : 1 if the tip of the dactyl were not broken in the Karubar specimen.
Alcock (1905b) remarked that the dactyls of the ambulatory legs were stout, compressed and curved, with the
third pair slightly longer than the second. In the Karubar specimen, the third pereopods also are longer than the
second, but whether the peg-like development of the dactyl of the left third (Fig. 40c) is characteristic of the
Karubar taxon or is attributable to injury cannot be determined from this single specimen. Only a spine at the
dorsodistal margin of the carpus of each ambulatory leg was reported in the description, but his figure (ALCOCK,
1905b, pi. 12, fig. 4) shows a proximal spine on the left second. Two proximal spines are present on the second
pereopods and one on the third in the Karubar specimen, as were illustrated, but not described, by ALCOCK
(1905a, pi. 68, fig. 3; 1905b, pi. 12, fig. 2) for N. gardineri.
The right sexual tube was described for N. indicus as a stout tube ending in a very long, lax, curly filament, the
left was short and blunt. In the Karubar specimen, the right is not particularly stout, but quite short, not
reaching to the coxa of the left fifth pereopod. However, it is possible that the more filamentous terminal portion
had been broken off. Variation in the development of the left sexual tube in species of Nematopagurus is not
uncommon, thus the absence of a left tube in the Karubar specimen would not, of itself, exclude the specimen
from N. indicus.

Rostrum broadly rounded, reaching level of lateral projections. Lateral projections each with marginal spinule.
Ocular peduncles moderately stout; slightly longer than antennal peduncles but reaching only to distal 0.75 of
ultimate segment of fully extended antennular peduncles, with tuft of stiff setae dorsally at base of dilated corneae.
Ocular acicles moderately small, terminating subacutely and with strong laterally produced submarginal spine,
giving bifid appearance (Fig. 20c). Antennal acicle somewhat arcuate, with terminal spine and stiff setae mesially,
reaching distal half of ultimate peduncular segment; flagellum long, with 1 or 2 short setae every 2 to 4 articles.
Chelipeds similar in form, sculpture and length; right (Fig. 40d) stouter; with numerous long fine setae,
particularly dorsally but not obscuring surface armature. Palm of right cheliped longer than broad and
approximately equal to length of dactyl; dorsomesial margin with row of spines, dorsal surface with median row of
spines not extending onto fixed finger; dorsolateral margin with row of spines extending only to proximal half of
fixed finger; ventral surfaces of dactyl, palm and fixed finger with moderately long setae. Carpus about as long as
merus and palm; dorsomesial margin with row of spines, dorsal surface with second longitudinal row of somewhat
smaller spines laterally; 1 spine on dorsodistal margin. Merus with 1 small spine on each ventral margin distally;
ventral surface with scattered low protuberances and few setae.
Left cheliped (Fig. 40e) with palm slightly shorter than dactyl; similar in armature and setation to that of right.
Carpus with dorsomesial and dorsolateral row of spines; 1 spine at dorsodistal margin. Merus with 3 widely-spaced
spinules on ventromesial margin; ventrolateral margin with 1 small spine distally.

several small spines, strongest near outer angles.
COLOR (based on N. gardineri sensu Haig & Ball, 1988). — Carapace with scattered red and white
chromatophores on semi-transparent background. Antennules light reddish brown distally. Antennae reddish brown.
Meri and carpi of chelipeds with large red spots on semi-transparent background. Carpi, propodi and dactyls of
ambulatory legs with reddish brown longitudinal stripes on semi-transparent background.
Habitat. — Questionably, gastropod shells with associated anemones.
Distribution. — Kai Islands and ? Arafura Sea, Indonesia; 758-212 m.
REMARKS. — Although the KARUBAR specimen is a small female, lacking paired first pleopods, it agrees well
with the general morphology of species of Nematopagurus. The sternal region of the fifth pereopods and anterior
portion of the abdomen are damaged; however, upon close inspection, two openings in the ventral integument,
corresponding in position to those of first pleopods can be seen. There is little doubt that it is correctly assigned to
this genus, and it bears certain similarities to ALCOCK's (1905a, b) N. gardineri , particularly in the seemingly bifid
structure of the ocular acicles. The acicles are not truly bifid, but the well developed submarginal spine is mesial in
position and clearly visible dorsally (Fig. 20b, c) giving the impression of a bifid acicle. Additionally, ALCOCK
specified that the ocular peduncles were equal in length to the anterior margin of the carapace, longer than the
antennal peduncles and reaching to the distal fourth of the ultimate segment of the antennular peduncles. The
KARUBAR specimen agrees in the ratios of ocular peduncle length to anterior shield margin and antennal peduncle,
but not antennular. In contrast, ALCOCK described and illustrated the corneae as not dilated. The ocular peduncles of
the Karubar specimen arc much stouter than ALCOCK illustrated for N. gardineri, and the corneae are clearly
dilated. His description of N. gardineri specifies a single spine at the dorsodistal marginal of the carpi of the
ambulatory legs, but his figure (ALCOCK, 1905a, pi. 68, fig. 3; 1905b, pi. 12, fig. 2) shows two and one
proximal spines on the denuded left second and third pereopods respectively; only a dorsodistal spine is present in
the Karubar specimen. Although the chelipeds are provided with an abundance of long fine setae in the KARUBAR
specimen, this pilosity does not begin to approach the density of the other Karubar specimen tentatively
assigned to N. indicus. This disparity is in marked disagreement with ALCOCK's (1905a, b) observations.

p. a. McLaughlin
Very few additional accounts of N. gardineri have been published. The first appears to have been KENSLEY's
(1969) report of the species from the International Indian Ocean Expedition's (IIOE) "Anton Briiun" Stn 390
(29°35'S, 31°42'E). KENSLEY gave only a cryptic account of his male specimen, but his figure (KENSLEY, 1969,
fig. 6e-h) illustrated a species agreeing, at least in armature of the chelipcds, with ALCOCK's description. However,
KENSLEY illustrated a specimen with ocular peduncles broadly expanded distally and with dilated comeae. Although
the type locality for N. gardineri in the Maidive Islands is in relatively close geographic proximity to KENSLEY's
IIOE station, conspecificity of his and ALCOCK's (1905b) specimens can not be confirmed at this point.
MlYAKE (1978) subsequently identified a species from Japanese waters as N. gardineri. While his single male
specimen from Sagami Bay agreed generally with most of the segmental ratios given by ALCOCK (1905a, b), it
apparently differed substantively in having unequal chelipeds. Miyake (1978) reported that the right was "vastly
larger" than the left. The ambulatory legs of MlYAKE's specimen were reported to have three spines "basally"
(presumably intended to mean proximally) on the carpi of the second pair, and 11 or 12 spines on the ventral
margins of the dactyls. It is very unlikely that MlYAKE's and ALCOCK's specimens are assignable to the same
taxon, nor that either is conspecific with the Karubar specimen.
Although Haig and Ball (1988) indicated that their three specimens, collected in the Arafura Sea during the
"Alpha Helix" expedition, agreed with the original ALCOCK (1905a, b) descriptions in most characters, they too
found exception in the shape of the ocular peduncles. Like the KARUBAR specimen, HAIG and BALL (1988) de¬
scribed their specimens as having peduncles "markedly expanded at the cornea." These authors also commented on
Miyake's (1978) record, noting that he did not mention the form of the ocular peduncles. Apparently they over¬
looked his reference to grossly unequal chelipeds. Since Haig and Ball's (1988) description was limited to notes
on living color and the comments on the ocular peduncles referred to previously, it is not possible to ascertain
whether or not their specimens and the KARUBAR female belong to the same taxon but, given the close proximity
of the collection sites, it is probable. It is doubtful that either are conspecific with ALCOCK’s (1905a, b) species.

Habitat. — Unknown.
Distribution. — Hawaiian Islands, Japan, Maldives, Indonesia; east coast of South Africa; 180 to 250 m.
AFFINITIES. — In having the dorsal surfaces of the chelae armed with numerous well-developed spines,
N. spinulosensoris superficially resembles N. muricatus. However, neither N. muricatus nor any other known
species of this genus are provided with the tear-drop sensory structures so characteristic of the spines of
N. spinulosensoris.
Remarks. — Turkay (1986) reported that he had examined the specimens identified as N. muricatus by
Thompson (1943) from the "John Murray" Expedition and by Miyake (1978) from Tosa Bay, Japan, and had
found these to actually represent N. spinulosensoris. Apparently neither of these latter authors noticed the
distinctive spines apparently unique to N. spinulosensoris.

(Figs 21g-h) with posterior lobes slightly asymmetrical, nearly subsemicircular; separated by deep median cleft;
terminal margins rounded, each with 1 or more rows of acute spines; lateral margins oblique, each (or at least left)
with row of small subacute spines increasing in size toward outer angle; dorsal surface frequently spinulose near
terminal margins.
COLOR (in preservative). — Spines and margins of scutes of chelipeds with faint pinkish orange tint; scutal
setae usually weakly iridescent.
FIabitat. — Not known.
Distribution. — Kai and Tanimbar Islands, Indonesia; 271-349 m.
ETYMOLOGY. — From the Latin scutella meaning small flat dish, and forma meaning shape, and referring to
the scute-like form of the ornamentation of the chelipeds.
AFFINITIES. — Nematopagurus scutelliformis sp. nov. shares several morphological peculiarities with
N. scutellichelis Alcock, 1905b, most notably in having the chelae and carpi ornamented with broad, Hat,
imbricating scutes; however, the two species are readily distinguished by the spination of the chelae and
ambulatory legs. Each chela of Nematopagurus scutelliformis has a row of spines on dorsolateral margin of the
palm distally and fixed finger proximally, that is absent in N. scutellichelis. Additionally, the dorsal surfaces of the
carpi of both ambulatory legs of N. scutellichelis are provided with a row of spines; the propodi are "ringed or
scutellated, the squames and scutes being nude and polished" (ALCOCK, 1905b: 113). The carpi of these appendages
in N. scutelliformis , although having numerous tufts of stiff setae, have only a dorsodistal spine and occasionally
one proximal spine on the second right pereopod; the propodi have short transverse setiferous ridges dorsally that
extend onto the lateral surfaces of the segments only slightly.
Remarks. Although N. scutelliformis is ostensibly very similar in appearance to N. scutellichelis, a
species reported only from very deep water (in excess of 1500 m) off the Maidive Islands in the Indian Ocean, there
is no doubt that the two taxa are distinct. Despite the fact that in some of the larger KARUBAR specimens, the
spines of the right cheliped tend to be obscured by stiff setae, those of the left are very distinct in individuals of
any size. It is improbable that ALCOCK (1905b) would have failed to observe such spines on the left chela in his
specimen(s), which, from the carapace measurement given, appear to be in the size range of the Karubar
specimens. However, even if he had, the differences in armature and ornamentation of the ambulatory legs provide
additional differentiating characters.

with few setae dorsally and ventrally. Anterior lobe of sternite of third pereopods (Fig. 23h) roundly
subrectangular, with long marginal setae. Fifth pereopods chelate.
Males unknown. Telson (Fig. 23i) with posterior lobes slightly asymmetrical, nearly subsemicircular;
separated by moderately deep median cleft; terminal margins rounded or slightly oblique, each with 2 to 4 large and
2 smaller spines; lateral margins slightly oblique.
COLOR (in preservative). — Segments of chelipeds and few spines retain faint small spots or patches of light
orange; bristle-like setae with yellowish tint.
DISTRIBUTION. — Known only from the type locality in Kai Islands, Indonesia; 85-124 m.
Etymology. — This species is named for A. Alcock, noted carcinologist of the Indian Museum, whose
monographic work on Indian Paguridea is still the cornerstone for regional studies.
AFFINITIES. — Nematopagurus alcocki appears most closely allied with N. australis , particularly in having
long, stiff irridescent setae on the mesial and lateral faces of the carpi of both chelae, and a covering of short setae
on the dorsal surfaces of the palms and fixed fingers. The ocular peduncles of Henderson's (1888) specimen from
the Arafura Sea are a little more slender than seen in the specimens of N. alcocki , and the corneae only slightly
dilated; however the peduncles of syntype from the Fiji Islands more closely approach those of the Karubar
species. Nonetheless, the two species are immediately distinguished by the dactyls of the chelipeds. The
dorsomesial margins of both dactyls are provided with a row of spines in N. australis, whereas they are completely
unarmed or may have one very small spine proximally in N. alcocki. Other differences include the spination of the
dorsal surface of the palm of N. australis that is lacking in N. alcocki, and the longer ocular peduncles of the
former species. HENDERSON described the carpi of the ambulatory legs as slightly spinulose. Only a dorsodistal
spine is actually present on each of these appendages, whereas the carpi of N. alcocki have one or two small spines
proximally on the dorsal margins, in addition to the dorsodistal spine.
Remarks. — Although this species is described from only female specimens, there can be little doubt as to
the accuracy of its assignment to Nematopagurus. In addition to well developed paired first pleopods modified as
gonopods in the holotype, N. alcocki has such additional generic characters as the small, deeply grooved ocular
acicles, reduced, rounded rostrum and clearly exposed interocular lobes, subequal chelipeds, and elongate ambulatory
legs with ventrally armed dactyls.
The paratype is an immature female, as the gonopores are quite small and the gonopods minute; only a
rudimentary left second pleopod is apparent. The chelipeds of this specimen have similar patterns of spination to
that described for the holotype; however, the spines are appreciably stronger. In contrast, the dorsal surfaces of the
chelae are not as abundantly provided with short setae and the characteristic bristle-like longer setae are weaker and
more sparse on both the chelipeds and ambulatory legs.
One additional female specimen (1.7 mm) (POLIPI) of Nematopagurus was found at stn DW 22, and probably
also represents N. alcocki; however, it is missing the chelipeds, left ambulatory legs, including the coxa of the
third, the coxae and sternite of the fifth pereopods, and the abdomen. This specimen is not considered a paratype,
even though the carpi of both right ambulatory legs have a very small proximal spine on the dorsal margin, and
the second has a tiny spine on the ventral margin of the merus.

segmentation. Maxillule with external lobe of endopod well developed, not recurved. Third maxilliped with well
developed crista dentata and very strong accessory tooth.
Right cheliped often not appreciably larger than left. Chela of right subrectangular to subtriangular; dorsal
surface of palm circumscribed by row of dorsomesial, dorsoproximal and dorsolateral marginal spines; angle of
propodal-carpal articulation approximately 15° from horizontal plane. Left chela with variable propodal-carpal angle
of articulation; dactyl elongate and considerably narrower than fixed finger; dorsolateral margin of chela elevated, at
least proximally, and frequently expanded. Fourth pereopods semichelate; propodal rasp consisting of single row of
corneous scales.
Males without paired pleopods or sexual tubes; with 3 unpaired, unequally biramous left pleopods. Females
with paired first pleopods modified as gonopods, with 4 unpaired biramous pleopods, second to fourth with both
rami well developed, fifth with endopod reduced.
Abdomen frequently straight or only weakly flexed. Uropods symmetrical or asymmetrical. Telson with
transverse suture, sometimes only weakly indicated; posterior lobes symmetrical or subequal, terminal margins
straight, oblique or rounded, armed; lateral margins each with undifferentiated, usually weakly calcified or chitinous
plate.
REMARKS. — McLaughlin (1981a) chose the generic epithet in the belief that species of the genus all were
endemic to the Southern Ocean. In their subsequent review of Australeremus, McLaughlin and GUNN (1992)
reassigned Eupagurus triserratus Ortmann, 1892, and Pylopagurus serpulophilus Miyake, 1978 (as a junior
synonym) from Japan to the genus, thus giving it a broad, but disjunct distribution. The discovery, not only of
A. triserratus, but of an additional new species in the Maluku region of Indonesia suggests that Australeremus
may be far more ubiquitous than previously believed and simply overlooked by collectors. At least several species
occupy habitats not routinely sampled, such as bryozoan and serpulid worm tubes.

Diagnosis. — Shield (Fig. 24a) slightly to considerably longer than broad. Rostrum acutely triangular. Ocular
peduncles slightly shorter than antennular peduncles. Ocular acicles acutely triangular, with strong submarginal
spine.
Right cheliped (Fig. 24c) with row of spines on dorsomesial margin of dactyl, dorsal surface with scattered low
or spinulose tubercles. Dorsomesial, dorsoproximal and dorsolateral margins of palm each with row of acute spines
entirely circumscribing palm and fixed finger; dorsal surface slightly convex and with numerous blunt or spinulose

P. A. MCLAUGHLIN
Ambulatory legs generally similar. Dactyls each with 7 to 1 1 corneous spines on ventral margin; propodi with
low protuberances on dorsal surfaces. Carpi each with 1 spine at dorsodistal angle, second often also with
1 additional spine on dorsal surface proximally. Sternite of third pereopods with subsemiovate anterior lobe.
Uropods symmetrical. Telson (Fig. 24g) with terminal margins of posterior lobes straight or slightly oblique,
armed with 2 to 4 strong spines and occasionally 1 or 2 small spines; lateral plates reduced.
Color (in preservative). — Ground color of body and legs light red-brown. Carapace with pair of dark
red-brown spots in front and behind cervical groove. Antennal flagellum with light and dark red-brown segments
alternatively. Chela and carpus dark red-brown; mcrus light red-brown with three dark colored cross-bands. Walking
legs light red-brown; meri and dactyls each with two dark colored cross-bands; carpi and propodi each with one dark
colored cross-band (after MIYAKE, 1978, pi. 4, fig. 4).
Habitat. — Serpulid worm tubes, at least in part.
Distribution. — Sagami Bay, Tanabe Bay, Amakusa, Japan; East China Sea; Bonin Islands; South China
Sea; Tanimbar Islands, Indonesia; 60 - 400 m.
Affinities. — Based upon the armature of the chelipeds and carpi of the ambulatory legs, McLaughlin and
Gunn (1992) suggested a possible relationship among the species, A. triserratus, A. steward (Filhol, 1883), and
A. eltaninae McLaughlin & Gunn, 1992. However, a much closer kinship now appears to exist with
A. indonesiensis sp. nov., as is discussed under that taxon.
Remarks. — The diagnosis given is here for the species in general, not just as characterized by the very small
Karubar specimen. This report of A. triserratus represents a considerable extension of the southern range of this
species. McLaughlin and Gunn (1992) earlier had documented its occurrence only as far south as the South
China Sea southwest of Kaohsiuhg, Taiwan. Despite its small size and the absence of the left cheliped, the single
specimen in the Karubar collection unquestionably represents A. triserratus. The right palm has the marginal
encirclement of spines characteristic of Australeremus and the median row of spines on the dorsal surface indicative
of A. triserratus.

ETYMOLOGY. — The specific name, indonesiensis, reflects the general geographic environs of this species,
only the second to be described from outside the "Southern" Ocean.
AFFINITIES. — As previously indicated, A. indonesiensis is morphologically most similar to A. triserratus.
Both species are characterized by the lack of armature on the dorsal margins of the segments of the ambulatory
legs. The lack of a median row of large spines on the dorsal surface of the right chela will immediately distinguish
A. indonesiensis from A. triserratus.

DIAGNOSIS. — Eleven pairs of phyllobranchiate gills. Rostrum variable. Ocular acicles simple, bifid or
multifid. Crista dentata well developed, with 1 or more accessory teeth. Sternite of third maxillipeds unarmed or
armed. Chelipeds generally grossly unequal, right usually appreciably larger. Dactyls of ambulatory legs
commonly with spinose ventral margins. Sternite of third pereopods variable. Fourth pereopods usually
semichelate, with 1 to several rows of scales in propodal rasp. Sternite of fifth pereopods variable.
Coxae of fifth pereopods generally symmetrical in both sexes. Males with paired gonopores; no paired
pleopods, usually with 3 or 4 unpaired left pleopods, rarely without unpaired pleopods. Females usually with
paired gonopores; no paired pleopods, usually 4 unpaired left pleopods, rarely only 3.
Abdomen usually spirally twisted, rarely straight. Uropods most commonly asymmetrical, occasionally
symmetrical. Telson typically with transverse suture; posterior lobes frequently separated by well developed median
cleft; terminal margins rounded, straight or oblique.
Remarks. — Pagurus is the "catch-all" genus for any hermit crab having 1 1 pairs of phyllobranchiate gills,
but lacking secondary sexual modifications or similar exclusive characters, and as such is the most specious, albeit
heterogeneous, of all pagurid genera. However, despite the widespread occurrence of more than 150 species
throughout the world's oceans, fewer than one quarter of those have been reported from the tropical Indo-Pacific.
In addition to the KARUBAR specimens, five species of Pagurus are known specifically from the Maluku area.
A small male of Pagurus cornpressipes (Miers, 1884) was the specimen from the Arafura Sea that HENDERSON
(1888) tentatively assigned to his "Pagurodes" piliferus. Although BuiTENDlJK (1937) published only on the
Diogenidae of the "Snellius" expedition, she did identify some of the Paguridae from that collection, among them a
specimen of P. hirtirnanus (Miers, 1880) from Wotap Island ("Tenimber Islands"), now part of the collection of
the National Museum of Natural History (USNM 122050). Haig and Ball (1988) reported P. hirtirnanus and
P. moluccensis Haig & Ball, 1988, from the Banda Islands, P. hedleyi Grant & McCulloch, 1906, from the
Arafura Sea, and P. pergranulatus (Henderson, 1896) from Seram.

COLOR (in preservative). — Distal halves of ocular peduncles and penultimate segments of antennular
peduncles orange. Chelipeds with overall faint orange tint, appreciably faded on chelae, but darker on carpi and
meri; meri also with splotches of white. Ambulatory legs each with longitudinal stripe of orange on lateral face of

Habitat. — Unknown.
Distribution. — Kai Islands, Indonesia; 210-268 m.
ETYMOLOGY. — The specific epithet is derived from the Kai Islands, the type locality of this species.
AFFINITIES. — Pagurus kaiensis does not appear closely allied to any of the other regional Pagurus species. In
small specimens, the general shape of the left chela approaches that of P. hirtimanus, but without the dense
setation of that species. In having long ambulatory dactyls and a single row of scales in the propodal rasp,
P. kaiensis resembles P. compressipes, but the two are immediately distinguished by the markedly different
armatures of the chelipeds (Figs 42g-h) and telson (Fig. 251) of the latter species.

Females unknown. Males with 4 unpaired left pleopods; second small and uniramous in holotype, all 4
unequally biramous in paratype; exopods moderately well developed, endopods absent or rudimentary. Uropods

COLOR (in preservative). — Ocular peduncles with patch or band of orange on dorsal surface proximally and
partial orange stripe on ventral surface. Ambulatory legs with orange at distal margins of meri, proximal and distal
margins of carpi and propodi and proximal margins of dactyls; distal tips of dactyls white.
Habitat. — Unknown.
Distribution. — Collected only in Tanimbar Islands, 184-210 m.
Etymology. — From the Latin capsula, meaning a case or box, and reflecting the presence of central
capsulate structures on many of the tubercles and spines on the dorsal surfaces of both chelae.
Affinities. — The shape of left chela in P. capsularis and the presence of four unpaired male pleopods is very
reminiscent of two other species found in the Maluku region, P. hirtimanus and P. pergramilatus (Haig & Ball,
1988). Pagurus capsularis is readily differentiated from P. hirtimanus by the lack of a dense covering of setae on
the chelae that is seen in the latter species. This new species is immediately distinguished from P. pergranulatus
by marked differences in the ventromesial margin of the merus of the right cheliped. This margin in
P. pergranulatus is developed into a distinct somewhat wing-like ventrally produced lobe and provided with a dense
tuft of setae; no such development of this margin occurs in P. capsularis. Differences in the shape and armature of
the right chelae in the two species, while also distinct, are less dramatic. In P. capsularis , the dorsodistal angle is
armed with spines, but not noticeably produced as a subacute lobe; the dorsal surface is armed with numerous
small spines and tubercles, with a somewhat irregular, more prominent row in the longitudinal midline. In
contrast, P. pergranulatus has the dorsodistal angle of the palm produced as a subacute lobe (cf. ALCOCK &
ANDERSON, 1897, pi. 31, fig. 1); the dorsal surface is provided with a series of granules each having what has
been described as an anterior concavity or central depression (HENDERSON, 1896). No reference has been made by
previous authors (e.g., Henderson, 1896; Alcock, 1905b; Haig & Ball, 1988) to distinctive capsulate
structures on the tubercles of the chelae of P. pergranulatus-, however, in the single specimen available for
examination (" Soela " station T 17/43, 19°47.4'S, 1 16°31.4'E, 56-57 m; MNT) structures similar to those described
for P. capsularis were observed. While the residual color patterns of the "Soela" specimen agree with those given
by Haig and Ball (1988) for P. pergranulatus, both clearly differ from the remnants of color in the specimens of
P. capsularis.

The presence of a median row of spines on the dorsal surface of the right chela and three irregular rows of
spines on the carpus of P. capsularis suggests a similarity with P. samoensis (Ortmann, 1892), but the Karubar
species differs from ORTMANN's in having the dorsal surface of the right chela strongly convex, and having much
shorter antennal acicles, but longer dactyls of the ambulatory legs.
REMARKS. — The capsules occupying the central surface of the tubercles of the chelae in both P. capsularis
and P. pergranulatus are reminiscent of the structures seen in Nematopagurus spinulosensoris. However, those of
the former two species have a more ball-like base and elongate, slender and drawn-out distal portion, whereas the
capsules of N. spinulosensoris are stouter and have a more tear-drop appearance. Since P. capsularis is known only
from the holotype and single paratype, no attempt has been made to determine the internal structure of these
capsules; nevertheless, a subterminal opening, similar to that observed in N. spinulosensoris, does appear to be
present. The capsules of that species were shown to be highly complex structures (MCLAUGHLIN & LANE, 1975).

Makarov, 1938. Like P. haigae, both of these species have strongly spinose and setose chelae; the carpi of the
ambulatory legs each carry a row of spines on the dorsal surface. Other characters shared by P. haigae and
P. brachiomastus include a pair of large tubercles on the ventral surface of the merus of the right cheliped, usually
densely setose lateral faces of the dactyl and propodus of the third left pereopod, and light or white colored band on
the distal portion of the meri of the chelipeds and ambulatory legs. However, the shortness of the dactyls and
spinose upper margins of the propodi of the ambulatory legs of P. brachiomastus, as well as its longer more
slender ocular peduncles, will immediately distinguish this species from P. haigae. As indicated by Miyake
(1978 : 98, text-fig. 37c) the dense setation on the lateral faces of the dactyl and propodus of the third left pereopod
is a character restricted to females of P. brachiomastus. No sexual dimorphism in this character was noted in the
Karubar specimens of P. haigae.
It is with P. yokoyai that P. haigae shares the greatest morphological likeness, and it would be impossible to
distinguish the two taxa based on the descriptions of Yokoya (1933) (as Eupagurus gracilipes Yokoya not
E gracilipes Stimpson, 1858) or Makarov (1938, 1962). Miyake's (1978) description provides much greater
detail, but only on the basis of color patterns and the illustrated telson (Text-fig. 45b) would differentiation be
teasible. Having compared the Karubar specimens of P. haigae with three male specimens of P. yokoyai there is
no doubt that the taxa are distinct. In addition to differences in the telson armature of the two species (Figs 27g-i),
the right cheliped of the latter species lacks the strong tubercuiate spines on the ventromesial margin of the merus,
the carpus is longer and narrower, and the spines of the dorsal surface of the chela are stronger. The left chela of
P. yokoyai is usually narrower and has fewer but stronger spines; the carpus is also narrower and the dorsomesial
margin more weakly armed. The second pereopods have five to eight corneous spines on the distal halves of the
ventral margins of the dactyls, and a double row of corneous spines on the mesial face dorsally.

Remarks. — Yokoya's (1933) description of Eupagurus gracilipes consisted of little more than a few
illustrations and remarks on its differences from Pagurus pectinatus (Stimpson, 1858). Makarov (1938, 1962)
noted, in a footnote to his diagnosis of Stimpson's (1858) P. gracilipes that, Yokoya's (1933) name was
preoccupied, and proposed that the species be called P. yokoyai. Makarov (1938, 1962) did suggest that
P. yokoyai was probably more closely related to P. brachiomastus than to P. pectinatus, which, in fact is the
case. Pagurus haigae, like P. brachiomastus and P. yokoyai, shares numerous characters with P. pectinatus, such
as strongly spinose and setose chelae; however, the much more elongate ocular peduncles and stronger rostrum of
the latter species clearly set it apart from the former three species.
Miyake's (1978, Text-fig. 44) illustration of P. yokoyai is indicated as a female, but with only three unpaired
left pleopods. This is either an illustrator's error or the sex of the illustrated specimen is incorrect, as it is most
unlikely that the second left pleopod would be absent in this Pagurus species. One of the three specimens
examined [d (8.5 mm) from Kushimoto, Wakayama, Japan] had well developed male gonopores, but four unpaired
pleopods. However, there was no indication of rhizocephalan infestation that might have attributed to this apparent
feminization.

Color. — Unknown.
Habitat. — Unknown.
DISTRIBUTION. — Known only from the type locality in the Kai Islands, Indonesia; 245-246 m.
ETYMOLOGY. — This species is named for Dr D. L. RAHAYU, Indonesian Institute of Sciences, in recognition
of her contributions to our knowledge of the regional hermit crab fauna.
AFFINITIES. — Bathypaguropsis rahayuae sp. nov. is the third species of this genus to be recognized, and
despite the overall morphological similarities among the three taxa, it is most closely allied to B. yaldwyni
McLaughlin, 1994. Although the ocular peduncles are shorter and the antennal acicles longer in B. yaldwyni , the
general armature of the chelae and carpi of the chelipeds would be comparable if intraspecific variability in
B. rahayuae was to approach that of B. yaldwyni. The terminal margins of the telson of B. rahayuae are armed
with spinules as they are in B. yaldwyni , although the number in the single specimen of B. rahayuae is smaller.
Nevertheless, the two species can be easily distinguished by the spines on the ventral margins of the ambulatory
dactyls, 15 to 31 in B. yaldwyni , but only 7 to 10 in B. rahayuae. The smaller number of dactylar spines is similar
to that of B. marionensis McLaughlin, 1994 (8 to 14); however, the strongly produced dorsomesial distal angle and
more numerous marginal spines of the right chela, as well as the armed ventromesial margin of the left, clearly
distinguish this species from B. rahayuae.

P. A. MCLAUGHLIN
Remarks. — McLaughlin (1994) noted that one adult specimen of B. yaldwyni was parasitized by an
unidentified rhizocephalan, and while female appearing pleopods were present, neither male nor female gonopores
could be detected. The holotype of B. rahayuae similarly had been infected by an unidentified rhizocephalan, but no
evidence of structural alteration nor feminization has been observed. Only normal male gonopores are present.

Remarks. — Haig and Ball (1988) reported two undescribed species of Pylopaguropsis from the
Alpha Helix expedition. Although both species, P. lewinsohni McLaughlin & Haig, 1989 and P. fimbriata
McLaughlin & Haig, 1989, had been recognized much earlier, their actual publication had been unavoidably
delayed. Neither species is represented in the Karubar material.

peduncles cream; acicles with margins accentuated in orange. Antennular peduncles cream, with faint
yellowish brown in distal third of ultimate segment. Antennal peduncles with orange stripe on ultimate
segment dorsally and on mesial face ventrally; fourth segment orange and white striped dorsally and white
ventrally; acicle with broad orange longitudinal stripe on dorsal surface. Right cheliped with chela faint orange or
cream-colored; carpus generally with faint orange hue, mesial, lateral and dorsal surfaces orange with white stripe
proximally. Merus orange and white striped dorsally and on dorsal halves of mesial and lateral faces, ventral surface
with faint orange hue. Left cheliped with chela very faint orange; carpus and merus with orange and white
longitudinal stripes. Second and third pereopods with orange and white longitudinal stripes (McLaughlin &
Haig, 1989).
Habitat. — Unknown.
Distribution. — Okinawa and Indonesia; 3-125 m.
Remarks. — Pylopaguropsis laevispinosa was described from two females collected in Okinawa, Ryukyu
Islands. The present diagnosis has been modified to reflect the variations exhibited by large males of this species.
The presence of P. laevispinosa in the Kai and Tanimbar Islands of Indonesia represents a major southern extension
of the range of this species.

Genus TOMOPAGUROPSIS Alcock, 1905
Tomopaguropsis Alcock, 1905b: 136.
DIAGNOSIS. — Thirteen pairs of trichobranchiate gills. Shield with well developed rostrum. Ocular acicles
triangular. Antennal peduncle with supernumerary segmentation. Maxillule with external lobe of endopod well
developed, recurved. Third maxilliped with well developed crista dentata and 1 accessory tooth. Sternite of third
maxillipeds with prominent spine on either side of midline.
Chelipeds subequal; right usually somewhat more robust. Ambulatory legs similar from left to right; carpus
with or without dorsodistal spine. Fourth pereopod semichelate; propodal rasp with several rows of corneous
scales. Fifth pereopods chelate.
Males with coxae of Fifth pereopods symmetrical; paired gonopores; with or without paired first pleopods
modified as gonopods, 4 unpaired unequally biramous left pleopods. Females with paired gonopores; no paired
pleopods, 4 unpaired pleopods, second to fourth usually with both rami well developed, fifth reduced. Telson with
transverse suture; posterior lobes separated by median cleft; terminal margins spinose.
TYPE Species herein selected. — Tomopaguropsis lantana Alcock, 1905b.
REMARKS. — ALCOCK (1905b) established Tomopaguropsis to accommodate his new species Tomopaguropsis
lantana , and Eupagurus Iproblematicus A. Milne Edwards & Bouvier, 1893, an Atlantic species. In his original
diagnosis of Tomopaguropsis , ALCOCK (1905b) reported that males were provided with a small pair of pleopods on
the first abdominal somite. Although no mention was made of paired male pleopods in the original description of
E. Iproblematicus , ALCOCK's assignment of this taxon to Tomopaguropsis presumably was based on
MILNE Edwards and Bouvier's (1893: 153) subsequent remark: "Cette espece se distingue des Eupagurus par
ses panes anterieures, dont les doigts sont mobiles dans un plan oblique, et par ses lamelles branchiales qui sont
profondement bifides a l'extremite. Ces deux caracteres, et la plupart des autres, la rapprochent des Parapagurus, et
Ton trouve meme chez le male deux fausses pattes sexuelles anterieures, reduites a l'etat de bourgeons tres courts,
ainsi que la trace d'une fausse patte sexuelle de la 2^me paire".
The presence of paired first pleopods modified as gonopods in Tomopaguropsis was the character that
Alcock (1905b) likened to the condition reported by Milne Edwards and Bouvier (1893) for their genus
Tomopagurus A. Milne Edwards & Bouvier, 1893. However, PROVENZANO (in FOREST & DE SAINT LAURENT,
1968) noted that normal males of Tomopagurus lacked paired first pleopods, and proposed that the presence of
paired first pleopods in the holotype of Tomopagurus rubropunctatus A. Milne Edwards & Bouvier, 1 893, was due
to the feminizing effect of a rhizocephalan of the genus Peltogaster; females of Tomopagurus were known to have
paired first pleopods. DE Saint Laurent (1970b) suggested that variation in the presence of paired pleopods in
both sexes probably occurred not only in Tomopagurus but in Tomopaguropsis as well. To demonstrate this
variation in Tomopaguropsis , she referred to an undescribed species which lacked male gonopods; in Tomopagurus
she cited the notation by Provenzano (in Forest & de Saint Laurent, 1968). McLaughlin's (1981a)
description of the new species, Tomopagurus wassi McLaughlin, a species lacking female paired first pleopods,
and her (MCLAUGHLIN, 1981b) description of feminization in a male of Rhodochirus McLaughlin, 1981a,
supported DE SAINT Laurent's suggestion for Tomopagurus. I have not reviewed the holotype of
Tomopaguropsis problematica , but I have examined four male specimens (UMML 4975, 4978-80); all lack paired
first pleopods. Similarly, males of T. crinita sp. nov. lack paired pleopods. In all other respects, males of both
species clearly are assignable to Tomopaguropsis.
ALCOCK (1905b) did not designate a type species for Tomopaguropsis , and the only other report of T. lantana
is that of Kemp and Sewell (1912) who noted the collection of one additional specimen during the 1910-1911
cruise of R.I.M.S.S. "Investigator". Although T. problematica was listed first in ALCOCK's (1905b) remarks, and
has been reported more frequently (e.g., Williams, 1984; Abele & KlM, 1986) it is probable that his generic-
diagnosis was based principally on the Indian taxon. Tomopaguropsis lantana, therefore, is herein selected as the
type species. Whether or not paired first pleopods in males of Tomopaguropsis is a normally variable condition
will only be determined when several males of T. lantana have been examined.

Color. — Unknown.
Habitat. — Unknown.
Distribution. — At present known only from the islands of Kai and Tanimbar, Indonesia; 1 1 1 - 346 m.
ETYMOLOGY. — From the Latin crinitus meaning long-haired, and referring to the very long setae of the
antennal acicles, ocular peduncles, chelipeds and ambulatory legs of this species.
AFFINITIES. — In having quite dense setation on the chelipeds and ambulatory legs, as well as elongate and
very prominent ocular acicles, T. crinita agrees with the description given by ALCOCK (1905b) for T. lantana.
However, T. crinita lacks the rows of spinules on the chelae reported for T. lantana. ALCOCK's (1905b, pi. 13,
fig. 4) depicts a dorsodistal spine on the carpus of each ambulatory leg of T. lantana-, T. crinita lacks any carpal
spine. In his generic diagnosis, ALCOCK attributed paired first pleopods modified as gonopods to males of
Tomopaguropsis, and these are depicted for T. lantana (ALCOCK, 1905b, pi. 13, fig. 4a). As previously noted,
male gonopods are not present in T. crinita, nor in the Atlantic species, T. problematica.

Male not known. Females with very unequally biramous pleopods. Posterior margin of sixth abdominal somite
with lateral angles rounded. Telson (Fig. 32h) with prominent transverse suture; posterior lobes nearly
symmetrical, separated by V-shaped median cleft; terminal margins rounded, each armed with 5 acute, corneous-
tipped and 2 very small spines on left, 5 on right, lateral margins not distinctly delimited.
Color. — Unknown.
Habitat. — Unknown.
DISTRIBUTION. — At present known only from the type locality in the Kai Islands of Indonesia; 390 - 502 in.
ETYMOLOGY. — This species is dedicated to the eminent Japanese carcinologist, Dr. Sadayoshi MIYAKE, in
recognition of his many contributions to our knowledge of the pagurid fauna of Japan.
Affinities. — Tomopaguropsis miyakei appears more comparable to T. lantana than to T. crinita. The dorsal
surfaces of the chelae of both T. miyakei and T. lantana are spinulose, while those of T. crinita are marked by
transverse rows of setae. However, there are very few spinules on the right chela of T. miyakei , in contrast to the
rows of spinules described by ALCOCK (1905b) for T. lantana. Two other differences between the two species are
apparent. For T. lantana the ocular acicles are reported to be long and stout, perhaps similar to the ocular acicles of
T. crinita. The ocular acicles of T. miyakei are neither long nor particularly stout. ALCOCK (1905b: 137) described
the chelipeds and ambulatory legs as being "very hairy, but not so thickly so as to entirely conceal the surface
sculpture". Although the chelipeds and ambulatory legs of T. miyakei are furnished with numerous sparse tufts of
long setae, the setation could not be considered analogous to that described and illustrated for T. lantana (ALCOCK,
1905b, pi. 13, fig. 4).
AC KNO WLEDGEMENTS
I am deeply indebted to Alain CROSNIER and Bertrand RICHER DE FORGES, both from ORSTOM, for providing
me with the opportunity to study this extremely significant collection. It was fortunate that two scientists more
specially involved in hermit crabs, Jacques FOREST of the Museum national d'Histoire naturelle, Paris, and Dwi
Listyo Rahayu of the Pulitsbang Oseanologi-LIPI from Ambon, were on board during the Karubar Cruise. It is
a testiment to their expertise that I have had such an excellent collection with which to work. Type materials from
the "Challenger" and "Alert" were graciously loaned by Paul CLARK, Natural History Museum, London. Valuable
comparative materials were provided by A. J. BRUCE, formerly of the Museums and Art Galleries of the Northern
Territory, Darwin, Australia, Michio IMAFUKU, Kyoto University, Kyoto, and Tomoyuki Komai, Natural History
Museum & Institute, Chiba, Japan, Rafael LEMAITRE, National Museum of Natural History, Smithsonian
Institution, and Nancy VOSS, Rosenstiel School of Marine and Atmospheric Sciences, University of Miami,
Miami, Florida. Technical assistance was provided by Janet ARMBRUST, Mt. Vernon, Washington. Photos are the
work of E. J. McGEORGE and Denis SERRETTE, Museum national d'Histoire naturelle, Paris. Mrs M. Joan
Thorne, Editorial Manager, Zoological Record, called my attention to a possible case of homonymy. To all I am
most grateful. This is a scientific contribution from the Shannon Point Marine Center, Western Washington

ABSTRACT
During the French-Indonesian Karubar campaign, ten species and a megalopal stage of deep-water hermit crabs of
the family Parapaguridae, were collected. Two of the species found in the collection are undescribed, Oncopagurus
glebosus sp. nov., and Paragiopagurus insolitus sp. nov.. and are characterized by several unusual or unique characters.
One previously described species, Oncopagurus orientalis (de Saint Laurent, 1972), was found to be insufficiently defined.
These three species are described or diagnosed, and illustrated. Another species, Parapagurus latimanus Henderson. 1888.
is reported for the first time from Indonesia. Two megalopal stage specimens of a parapagurid species cannot be assigned
with certainty based on current knowledge, to any species; they are also illustrated and discussed. A list of all
15 parapagurid species currently known from Indonesian waters is presented, including references where diagnoses and
illustrations can be found.

Descriptions de deux especes nouvelles.
Durant la campagne franco-indonesienne Karubar, 10 especes et un stade megalope de pagures d’eau profonde de la
famille des Parapaguridae ont 6t6 recoils. Deux de ces especes sont nouvelles: Oncopagurus glebosus et Paragiopagurus
insolitus et se distinguent par plusieurs caractires inhabituels ou uniques. Une espece decrite precedemment, Oncopagurus
orientalis (de Saint Laurent, 1972) s'est reveUe mal definie. Ces trois especes sont done l'objet d'une description ou d'une
diagnose et sont illustrees. Une autre espece, Parapagurus latimanus Henderson, 1888. est signalee pour la premiere fois
d' Indonesie. Deux megalopes de Parapaguridae ne peuvent etre rattachees avec certitude h aucune espece connue; elles sont
egalement illustrees et discuses. Une lisle des 15 especes de Parapaguridae, connues des eaux indonesiennes, est etablie,
accompagnee de references oil des diagnoses et des illustrations les concemant peuvent etre trouvdes.

R. LEMAITRE
INTRODUCTION
The family Parapaguridae Smith, 1882, redefined by DE Saint Laurent (1972), in recent years has been the
subject of revisionary studies that have established new generic boundaries and proposed a number of new genera
(Lemaitre, 1989, 1993, 1996; Osawa, 1995). As result, ten genera are now recognized, five of which are
monotypic: Probeebei Boone, 1926, Tylaspis Henderson, 1885, Typhlopagurus de Saint Laurent, 1972,
Bivalvopagurus Lemaitre, 1993, and Tsunogaipagurus Osawa, 1995; five others contain the remainder of the
species: Parapagurus Smith, 1879, Sympagurus Smith, 1883, Strobopagurus Lemaitre, 1989, Oncopagurus
Lemaitre, 1996, and Paragiopagunis Lemaitre, 1996.
The parapagurid fauna from Indonesia is known largely from collections obtained in earlier expeditions such as
the U.S. “Albatross" (late 1800's to early 1900's), Dutch Siboga Expedition (1899-1900), the Danish
Th. Mortensen’s Pacific Expedition (1914-1916), and the Danish Galathea (1950-1952). Based on these
collections, 12 species of parapagurids have been reported from various Indonesian localities (DE SAINT LAURENT,
1972; Lemaitre, 1994, 1996).
During the recent French-Indonesian deep-water sampling campaign known as Karubar, conducted from
October to November of 1991 on board the " Baruna Jaya I", seven of the 12 species known to occur in the
Indonesian region were obtained. In addition, the Karubar material was found to contain two distinctive new
species, Oncopagurus glebosus sp. nov., and Paragiopagunis insolitus sp. nov., described herein. One species,
Parapagurus latimanus Henderson, 1888, had not been previously reported from this region. Another species in
this material, previously included in the genus Sympagurus, S. orientalis (de Saint Laurent, 1972), but recently
assigned by Lemaitre (1996) to the genus Oncopagurus, was found to be insufficiently defined. It is illustrated
and diagnosed. Also reported and discussed are two megalopal stage specimens of an undetermined species of
parapagurid. Although based on current knowledge these postlarvae cannot be assigned to any species, they are of
interest because of the paucity of information on the larval development of parapagurids (Lemaitre &
McLaughlin, 1992).
The Karubar material remains deposited in the Museum national d’Histoire naturelle, Paris (MNHN), except
lor some duplicates deposited in the National Museum of Natural History, Smithsonian Institution, Washington
D C- (USNM). For comparative purposes, paratypic material of Oncopagurus orientalis (de Saint Laurent),
borrowed from the Zoologisch Museum, Amsterdam (ZMA), and Zoologisk Museum, Copenhagen (ZMK), was
examined.
In the material examined section, the length of the shield (to the nearest 0.1 mm), indicated in parentheses, is
measured from the tip ol the rostrum to the midpoint of the posterior margin of the shield. Measurements included
for the megalopae are carapace length (CL), measured from the tip of the rostrum to the posterior midpoint of the
carapace; and total length (TL), measured from the tip of the rostrum to the midpoint of the telson, excluding the
telsonal setae. Abbreviations used are: unmat. , immature (sex indetermined); ovig., ovigerous; Stn, station.
The Karubar campaign was named for the islands of Kai, Aru, and Tanimbar.
The general terminology employed follows McLaughlin (1974). In the descriptive text, the term
semichelate to describe the condition of the fourth and fifth pereopods, is used following McLaughlin’s (1997:
435) definition, i.e. "where the ventral margin of the propodus is produced beneath the dactyl to such an extent that
flexion of the dactyl becomes more akin to the action of a dactyl against a fixed finger of a chelate appendage”.
This is in contrast with the "subchelate” condition, "in which the pereopod is developed as a prehensile structure
by the folding back of the dactyl against the propodus”.

Distribution. — Indo-Pacific: Madagascar; Indonesia: and Australia. Depth: 205 to 960 m.
Remarks. — As pointed out by Lemaitre (1996), this species is very similar to S. dofleini (Balss, 1912).
Females of S. papposus can be separated from males or females of S. dofleini by the armature of the anterior lobes
of the telson. The left anterior lobe of the telson, and sometimes also the right anterior lobe, are armed
ventrolaterally with a fringe or cluster of slender corneous spines mixed with bristle-like setae in S. papposus. The
anterior lobes have in both sexes at most a row of setae in S. dofleini. Males of the two species, however, can
only be separated using a number of subtle differences. The anterolateral projections of the shield are broadly
rounded, often obsolete, in 5. papposus-, the projections are broadly triangular, often terminating acutely in
S. dofleini. The spines on the antennal scales are stronger, and more broadly spaced in S. papposus than in
5. dofleini. The distal lobe of the male first gonopod is broader in S. papposus than in S. dofleini. The two
species also seem to utilize different habitats or symbiotic associations. S. papposus has been found living
exclusively in large zoanthids ( Epizoanthus sp.) whereas 5. dofleini is most frequently found living in large
actinians ( Stylobates sp.).

posterior lobes separated by shallow U-shaped median cleft, right lobe weakly developed (frequently obsolete),
terminal margins armed with often strongly curved corneous spines. Male lacking first gonopods; second gonopods
(Fig. lh) vestigial or rudimentary, unsegmented, usually paired, asymmetrical, or sometimes with unpaired left.
Females with vestigial right second pleopod.
Habitat and symbiotic Associations. — The Karubar specimens were found living in coarse-textured
zoanthids. Other specimens have been found in gastropod shells.
Distribution. — Indo-Pacific: Philippines; Moluccas; Indonesia. Depth: 300 to 575 m.
Remarks. — Oncopagurus orientalis is one of four Oncopagurus species in which males lack first gonopods
and the second gonopods are vestigial or rudimentary. The others are O. haigae de Saint Laurent, 1972, O. tuamotu
Lemaitre, 1994, and O. cidaris Lemaitre, 1996. The multifid condition of the ocular acicles in O. orientalis is the
most obvious character that immediately distinguishes this species from the other three. Although the four species
are otherwise superficially similar, they differ in such characters as the shape and armature of the right cheliped;
relative length of dactyls of ambulatory legs; presence or absence of sexual dimorphism in the dactyl of the fourth
pereopod; and in males, degree of development of the second gonopods.
The right palm of O. orientalis shows some degree of variability in length, and also in armature of the ventral
face. As expected, such variabilty is related to size and sex of the individuals. The palm of the male holotype, for
example, is longer than broad (Fig. 2a), whereas in Karubar females the palm is broader than long (Fig. 2c). The
armature of the ventral face can consist of scattered small tubercles (Fig. 2b), or scattered small tubercles and
moderately large tubercles often arranged in an oblique row (Fig. 2d).

Remarks. — Oncopagurus glebosus sp. nov. is distinguished not only from all its congeners but from all
other parapagurids, by the unique condition of the ocular acicles. This is the only species in the family known to
have ocular acicles with a submarginal spine. The ocular acicles in all other parapagurids (except the highly
specialized Tylaspis anomala Henderson, 1885, which lacks acicles), terminate in a simple to multifid marginal
spine.
The distinct armature of the ventral surface of the right palm also distinguishes O. glebosus sp. nov. from
other Oncopagurus species. The ventral surface has numerous irregularly arranged tubercles, some of which
frequently form a prominent cluster medially (Fig. 3d). The cluster is usually markedly raised above the surface; in
586
R. LEMAITRE
small individuals (SL < 1 .5 mm) it is not as prominent, and the tubercles may be smaller and wider apart than in
large individuals. The presence of prominent armature in the form of spines or variously shaped tubercles on the
ventral face of the right chela is a condition present in three other parapagurid species, Paragiopagurus boletifer (de
Saint Laurent, 1972), P. rugosus (de Saint Laurent, 1972), and Tsunogaipagurus chuni (Balss, 191 1).

Habitat. — Unknown (probably gastropod shells).
Distribution. — Known so far only from the Kai Islands, Indonesia. Depth: 448 to 467 m.
Etymology. — The specific name is from the Latin insolitus, unusual. The name is given for the unusual
condition of the ocular acicles, epistome, maxillipeds, and fourth pereopods.
REMARKS. — Paragiopagurus insolitus sp. nov. is a singularly distinctive species. The shape or conformation
of the ocular acicles, mouthparts, epistome, and dactyl of the fourth pereopod, are unusual or unique among
parapagurids. The relative length of the terminal spine of the ocular acicles is the longest known for any
parapagurid, and usually reaches nearly to midlength of the ocular peduncles. The incisor process of the mandible is
unusual in that it consists of several irregularly-shaped teeth (Fig, 8a), rather than having a single small median
tooth as in all other parapagurids for which the mandibles have been described. The second and third maxillipeds
each have a very long and slender exopod that is nearly 10 times as long as broad (Fig. 8e-f); in other parapagurids
the exopod is at most six times as long as broad. The epistome is strongly produced anteriorly, forming a
somewhat pyramid-shaped process with a concave ventral face (Fig. 7c); in other parapagurids the epistome is
evenly rounded.
The specialized setal arrangement seen on the dactyl of the fourth pereopod of P. insolitus sp. nov., is unique
among parapagurids (Fig. 10a). The claw of the dactyl is almost entirely masked by long plumose setae that arise
near the base and all around the claw. Although the function of this setal arrangement is unknown, it bears some
similarity with that reported by DE Saint Laurent (1968a, b) and McLaughlin (1997) for species of the
pagurid genus Decaphyllus de Saint Laurent, 1968.

Remarks. — Although the two megalopal stage specimens reported herein evidently belong to the
Parapaguridae, they cannot be assigned with certainty at the present time to any particular species. The complete
larval rearing for any parapagurid species has not been achieved beyond the second zoeal stage (WILLIAMSON &
von Levetzow, 1967; Provenzano unpublished). The two Karubar specimens are identical morphologically,
and appear to be of the same species.
Of the two Karubar stations where parapagurid megalopae were obtained, no adult parapagurid stages were
found at Stn CP 59. Adult specimens of Parapagurus latimanus and Oncopagurus minutus were obtained at
Stn CP 87; conceivably the megalopae might be of one of these two species. However, O. minutus is a species
whose adult individuals are small, growing rarely to the size of the Karubar megalopae. Based on station co¬
occurrence and size, it is more likely that the megalopae are of P. latimanus, a species whose individuals can grow
to a size considerably larger than these postlarvae.
The Karubar specimens show similarities with the megalopae assigned by Lemaitre & McLaughlin
(1992: 754, Figs 6-7) to Sympagurus dimorphus (Sluder, 1883), but clearly differ at least in the cephalic shield,
development of the rostrum, and armature of the chelipeds. The shield in the Karubar megalopae (Fig. 1 la) has
a more pronounced and longer median longitudinal ridge on the anterior half than in S. dimorplius. The rostrum is
terminally rounded in both the Karubar and S. dimorphus megalopae; however, in the former, the rostrum has
a membranous ventral extension (Fig. 1 la-b) that is more developed than in the latter. The right and left chelipeds
of the Karubar specimens have spines or small tubercles on the dorsomesial margins of the palm and dactyl, and
on the dorsal margin of the carpus (Fig. 1 lc-d); the chelipeds are unarmed in the megalopae assigned to
S. dimorphus.

GENERAL REMARKS AND LIST OF INDONESIAN PARAPAGURIDS
Recent studies based largely on specimens obtained during the Karubar campaign indicate that the Indonesian
region harbors a previously unrecognized impressive diversity of hermit crabs of the family Paguridae
(McLaughlin, 1997). The Indonesian parapagurid fauna contains a total of 15 species, or about 25% of the
59 species of the family currently known worldwide, and evidently does not approach the species richness of the
Paguridae from the region. However, the discovery of two new species, Oncopagurus glebosus and Paragiopagurus
insolitus, characterized by unusual or unique conditions previously unknown in the family, are indicative of the
broad range of morphological diversity that exists in the Parapaguridae.
The following is a list of the 15 species and megalopa of Parapaguridae currently known from Indonesian
waters, including references where diagnoses and illustrations can be found. An asterisk indicates that the species
was not obtained during the Karubar campaign.

ABSTRACT
Twenty six species of galaiheid crustaceans belonging to the genera Agononida Baba & de Saint Laurent, 1995 and
Munida Leach. 1820, were caught off the Molucca archipelago, during the Karubar Cruise (October-November, 1991).
Three species are described as new: A. emphereia, M. compacta and M. punctata.
RESUME
Crustacea Decapoda : Especes des genres Agononida Baba & de Saint Laurent, 1995 et Munida
Leach, 1820 (Galatheidae) recoltees lors de la campagne KARUBAR.
Les espfeces des genres Agononida Baba & de Saint Laurent. 1995, et Munida Leach, 1820, recoltdes dans 1 archipel
des Moluques sont au nombre de 26. Trois espbces (A. emphereia, M. compacta et M. punctata) sont nouvelles.
A. emphereia, proche de A. soelae (Baba, 1986) et de A. incerta (Henderson, 1888) se differencie facilement par
l'armature de la carapace. M. compacta est proche de M. rhodonia Macpherson, 1994, mais se differencie par la forme et
l'armature des chelipcdes. M. punctata se distingue de M. rubrodigitalis Baba, 1994, par la forme du rostre.
INTRODUCTION
The genera Agononida Baba & de Saint Laurent, 1995 and Munida Leach, 1820 are represented in Indonesian
waters by more than 15 species (Baba, 1988; Baba & de Saint Laurent, 1995; Macpherson, 1993, 1994;
MACPHERSON & Baba, 1993). During a recent cruise (Karubar) carried out in October-November

1991 to the Molucca Archipelago (Kai and Tanimbar islands) (see CROSNIER et all., 1997), numerous
representatives of these genera were collected. The aim of this paper is to study this interesting collection.
The types of the new species and other material have been deposited in the collections of the Museum national
d'Histoire naturelle, Paris (MNHN), the Puslitbang Oseanologi-LIPI, Jakarta (POLIPI) and the National Museum
of Natural History, Washington. When no information on the depository is provided, the material is held by the
MNHN, Paris. Measurements given are of carapace length excluding rostrum, and the terminology used mainly
follows previous papers (MACPHERSON & de SAINT Laurent, 1991). In order to avoid repetitious descriptions,
only distinctive characters have been included in the text.

SYSTEMATIC ACCOUNT
Genus AGONONIDA Baba & de Saint Laurent, 1995
Agononida emphereia sp. nov.
Fig. 1
Material EXAMINED. — Indonesia. Karubar: stn 21, 688-694 m: 1 $ 18,5 mm (MNHN-Ga 3947); 3d 18.2 to
21.4 mm; 1 ov. 2 20.5 mm (MNHN-Ga 3948).
TYPES. — The male of 18.5 mm from the Stn 21 (MNHN-Ga 3947) has been selected as holotype, the other
specimens are paratypes.
ETYMOLOGY. — From the Greek, emphereia, likeness (considered here as a substantive in apposition), in
reference to the similarity between the new species and other closely related species.
DESCRIPTION. — Carapace with numerous secondary striae and scales. One protogastric spine behind each
epigastric spine (practically absent in one specimen). One small spine on hepatic region, usually on each side.
Three or four spines in a row on each branchiocardiac boundary, anteriormost postcervical, larger than remainder.

E. MACPHERSON
Cardiac region with 1-2 spines (absent in one specimen). Posterior border of carapace unarmed. Anterolateral spine
pronounced, situated at anterolateral angle of carapace. Branchial margins with 4 spines. Fourth to seventh thoracic
sternites with numerous short arcuate striae. Second, third and fourth abdominal segments each with 4 spines on
anterior transverse ridge; posterior ridge of fourth segment with strong median spine. Eye moderately large,
maximum corneal diameter about 1/3 length of anterior border of carapace between bases of external orbital spines.
Basal antennular segment (distal spines excluded) not exceeding eye, distolateral spine shorter than distomesial.
Distomesial prolongation of first antennal segment well developed, reaching rostral tip; second segment with
2 strong distal spines, distomesial spine slightly overreaching third segment, 1-2 spines on mesial border; third
segment unarmed. Flexor margin of merus of third maxilliped with median spine, extensor border with distal
spine. Fingers of cheliped unarmed, fixed finger bifid distally. First walking leg about 3 times carapace length.
Dactylus of walking legs about 2/3 propodus length, armed with small spine-like setae on median third of ventral
border.
Remarks. — The new species is closely related to A. soelae (Baba, 1986) from North-West Australia,
New Caledonia and Indonesia and A. incerta (Henderson, 1888) (see below) in the general spination of the
carapace. The three species have spines on the anterior and posterior ridges of the fourth abdominal. The new
species differs from A. soelae in the following aspects:
— The carapace and sternal plastron are less rugose in A. soelae than in the new species.
— The distomesial prolongation of the first antennal segment is short in A. soelae , reaching the end of the
second segment of the antennal peduncle; this prolongation is very long in the new species, clearly overreaching
the antennal peduncle and reaching rostral tip.
— The posterior border of the carapace is unarmed in the new species, whereas A. soelae has 4-6 spines.
The extensor border of the merus of the third maxilliped is armed with one distal spine in A. emphereia,
unarmed in A. soelae.
The new species is distinguished from A. incerta by the following characters:
— Two protogastric spines in the new species, absent in A. incerta.
One small hepatic spine, usually on each side, is present in A. emphereia , absent in A. incerta.
The cardiac spines are always absent in A. incerta , whereas in A. emphereia they are usually present.
Distribution. — Indonesia, between 688 and 694 m.

Remarks. — Agononida similis is closely related to A. squamosa Henderson. 1885 (see below). Both species
can be distinguishable by the shape of the rostrum and the mesiodistal spine of the first segment of the antennal
peduncle (Baba, 1988). The specimens examined here always have the posterior border of the carapace without
spines, whereas in all other specimens of A. squamosa examined two spines are present. Although Baba (1988)
showed certain variations in the presence of these spines, the constancy here observed suggests that this character
may have a specific value.

Remarks. — The specimens examined are not well preserved and the antennular peduncles of many specimens
are broken. Therefore, one of the important specific characters (the length of the distal spines) is often unknown.
Most of the morphological characters agree quite well with the description of M. agave. However, the number of
spines along the anterior border of the second abdominal segment is variable (0 to 6) and in one specimen the
thoracic sternites are squamate (smooth in M. agave). As it was pointed out in the original description,
probably more than one species are included in this complex. Therefore, in view of the difficulties in the
correct identification, the present material is provisionally referred to M. agave until more specimens become
available.

ETYMOLOGY. — From the Latin, compactus , thick, in reference to the shape of the carapace.
Description. — Carapace with numerous secondary striae. Intestinal region with numerous scales.
Anterolateral spine well developed, situated at anterolateral angle. Branchial margins with 5 well developed
spines. Fourth thoracic sternite with a few short arcuate striae; fifth to seventh without striae. Abdominal
segments with numerous transverse striae; second segment with 9-11 spines on anterior ridge. Eye large,
maximum corneal diameter about 2/5 length of anterior border of carapace between bases of anterolateral spines of
carapace. Basal segment of antennule (distal spines excluded) ending at same level of cornea, distal spines
subequal. First segment of antennal peduncle with distomesial spine nearly reaching end of second segment;
distomesial spine of second segment exceeding third segment, usually with accompanying small spine proximally.
Extensor margin of merus of third maxilliped unarmed. Distomesial spine of cheliped merus well developed,
reaching midpoint of carpus. Fixed finger with one distal spine; movable finger with basal spine. First walking leg

about twice carapace length; dactylus as long as propodus, with spine-like setae reaching distal part of ventral
margin.
Remarks. — Munida compacta is closely related to M. curvirostris Henderson, 1885 (see below). Both species
have five spines on the lateral margins of the carapace behind the cervical groove, the front margins are transverse,
the eyes are large, the abdominal segments have spines along the anterior ridge of the second tergite, the lateral
portions of the posterior thoracic sternites have no granules, the distal spines on the basal antennular segment are
subequal and the extensor margin of the merus of the third maxilliped is unarmed. However, the species are easily
differentiable in several regards. The new species has numerous secondary striae and scales on the carapace and
abdominal segments (more than 5 secondary striae on the second abdominal segment). These striae and scales are
practically absent in M. curvirostris (less than 5 secondary striae on the second abdominal segment). Furthermore,
in M. compacta the dactylus of the walking legs is as long as the propodus, whereas in M. curvirostris the
dactylus is clearly shorter than the propodus.
The new species also resembles Munida rhodonia Macpherson, 1994, from New Caledonia, Loyalty and
Chesterfield Islands (Macpherson, 1994).
However, they can be distinguished by several differences:
— The chelipeds are clearly different. They are more massive in M. rhodonia than in the new species and
the spines on the dorsal side of the palm are very small in M. rhodonia , whereas they are well developed in the
new species. Moreover, in the new species, the distomesial spine of the merus of the cheliped reaches or
overreaches the midlength of the carpus; in M. rhodonia , this spine usually does not reach the midlength of this
article.
— In M. rhodonia the dactylus of the first walking leg is clearly shorter than the propodus. In the new species
the dactylus is as long as the propodus.
Distribution. — Indonesia, between 246 and 694 m.

Remarks. — The specimens examined agree quite well with the type material. However, in some the movable
finger of the chelipeds has some spines along the mesial border (only one basal spine in the types). Furthermore,
the dactylus of the walking legs in the specimens from Stn 14 are unarmed on the tetminal third ot the ventral
margin (armed with movable spines along the whole border in the types). These differences suggest the existence
of several forms or species (see also MACPHERSON, 1995). Munida leptitis was described from only two
specimens collected in New Caledonia and Loyalty Islands, therefore the discovery of additional topotypic
specimens would be desirable in order to determine the variability of the species and to confirm the identity of the
present material.
Distribution. — New Caledonia and Loyalty Islands, between 21 and 440 m (Macpherson, 1994), Wallis
and Futuna area (MACPHERSON, 1995). The specimens from Indonesia were collected between 206 and 299 m.

b. rostrum, lateral view; c. sternal plastron; d. ventral view of cephalic region, showing antennular and antennal
peduncles; e, right third maxilliped. proximal segments of endopod, lateral view; f. right cheliped. dorsal view;
g, right first walking leg, lateral view; h. dactylus of right first walking leg, lateral view.
ETYMOLOGY. — From the Latin, puncta , point, puncture, in reference to the red point near the rostrum lip.
DESCRIPTION. — Carapace with numerous secondary striae. Intestinal region with some median scales.
Rostrum spiniform, not laterally compressed. Anterolateral spine moderately short, situated at anterolateral angle.

not reaching level of sinus between rostrum and supraocular spine. Branchial margins with 5 small spines.
Thoracic sternites with numerous short arcuate striae. Second abdominal segment with 8-9 spines along anterior
transverse ridge. Second and third segments each with some transverse striae. Males with two gonopods on first
and second abdominal segments. Eye large, maximum corneal diameter about 1/2 length of anterior border of
carapace between bases of external orbital spines. Basal segment of antennule (distal spines excluded) ending at
level of cornea, distal spines subequal. First segment of antennal peduncle with short distomesial spine, clearly'not
reaching end of second segment; distomesial spine of second segment long, barely exceeding antennal peduncle.
Extensor margin of merus of third maxilliped unarmed. Distomesial spine of cheliped merus well developed,
though not reaching midpoint of carpus. Movable finger of chelipeds with basal spine, fixed finger with terminal
spine. First walking leg about twice carapace length. Dactyli of walking legs slightly shorter or as long as
propodus, with spinules along entire ventral margin.
Remarks. — The new species resembles Munida rubrodigitalis Baba. 1994, from northeastern Australia, New
Caledonia, Loyalty Islands and Indonesia (Baba, 1994; Macpherson, 1994, see also below). Both species have
five spines on the branchial margin, the second abdominal segment armed with spines along the anterior ridge, the
distal spines on the basal antennular segment subequal, short chelipeds and a red, distal mark on the rostrum
(specimens in preservative). However, they can be easily distinguished by the shape of the rostrum, which is
laterally compressed in M. rubrodigitalis, whereas in the new species it is clearly spiniform.
Distribution. — Indonesia, between 336 and 502 m.

INTRODUCTION
This report is based on the collections taken during a Franco-Indonesian expedition in Indonesia (Karubar,
1991), and two French expeditions at Wallis and Futuna Islands (MUSORSTOM 7, 1992) and off New Caledonia
(Bathus 3, 1993).
Eleven species, belonging to 3 genera, have been identified, of which one genus and 5 species are described as
new, and 3 species (marked with an asterisk in the accompanying list) are reported for the first time from
Indonesia.

SYSTEMATIC ACCOUNT
Subfamily ETHUSINAE Guinol, 1977
Genus PARETHUSA nov.
DIAGNOSIS. — Carapace longer than broad, swollen, dorsal and ventral surfaces smooth. Grooves and regions
very indistinct. Front thin, separated into 2 broadly triangular teeth (the external side of the two median frontal;
teeth is angled, suggestive of the beginning of a tooth) by a large, V-shaped notch. Basal segment of antennules
not swollen, eyes located on ventral surface, eye-stalks short, stout and movable. Last two legs short and small,
dactyli talon shaped.
TYPE species. — Parethusa glabra sp. nov. by present designation.
Gender. — Feminine.
ETYMOLOGY. — The name is formed by a combination of the Greek word par (near) and the feminine name
Ethusa.
Remarks. — This new genus is closely related to Ethusa and Ethusina. but may be distinguished from them
by the following:

The new genus is characterized by the presence of talon-shaped dactyli on the last two legs, the long and slender
second pleopods and the teeth of the front (2 broadly triangular ones). I am inclined to consider Parethusa as a
primitive member of the Ethusinae.

produced at distal 1/7, and both borders of distal end with some spines. Male second pleopods slender, tip sharp.
Etymology. — The name is formed by a combination of the Latin dilatus (expanded) and dens (tooth), in
reference to the shape of the exorbital teeth.
Remarks. — The new species is similar to Etlwsa sexdentata (Stimpson, 1858) in ihe shape of the carapace,
but can easily be distinguished from it by the exorbital teeth being broader than long, its outer border converging
inwards, the symmetrical male chelipeds, and the form of ihe male first pleopod. Ethusa dilatidens is also similar
10 E- obliquidens Chen, 1993, bul differs from the latter in having the exorbital teeth longer than broad ; the telson
of male abdomen broadly triangular or semi-circular ; the first segment 1.5 times longer than the second; and the
distal end of first pleopods blunty rounded.

ABSTRACT
F.chinodermata Crinoidea: Pentacrinidae collected during the Karubar Cruise in Indonesia.
The stalked crinoids collected during the Karubar cruise (Kai and Taninibar Islands: Indonesia) belong to the genus
Saracrinus (Pentacrinidae). Three species in this genus are described, one of which, S. moosai, is new. The samples come trom
depths between 210 and 430 m. This pentacrinid fauna is abundant (165 specimens) but less diverse than the rich launa
collected elsewhere in Indonesia (Sulu Sea, Celebes Sea, Timor Sea, Banda Sea, Java Sea). Twelve species ol pentacnmd were
sampled by previous cruises: Saracrinus angulalus, S. suluensis, S. aculus , S. cingulatus, S. murrayu S. batheri, S.nobilis,
S. superbus, S. varians, Metacrinus serraius, Diplocrinus sibogae, Hypalocrinus naresianus. Data on morphological features,
biometry, arm branching and ossicle articulations are given for each species collected during the Karubar cruise. Stalk, arm
and pinnular joints were observed using scanning electron microscopy with regard to their taxonomic importance. As
numerous individuals of each species were collected, it was possible to study the variation of crown and stem characters. It
appears that the stems and arms of these species, and especially for S. angulatus, exhibit intraspecific polymorphism. One ot
the consequences of these studies is a reduction of the number of recognised species. Some of these forms are interpreted as a
consequence of ecophenotypic or geographical variations. Thus, for example. 5. suluensis, S. aculus, S. cingulatus and
5. batheri are synonyms of S. angulatus, while S. superbus and S. varians are synonyms of 5. nobilis.

INTRODUCTION
Les differentes expeditions du siecle dernier [celles du "Challenger", 1873-1876 (P.H. Carpenter, 1884) et de
la "Siboga", 1899-1900 (L. DODERLEIN, 1907, A.H. Clark, 1908a)] et la campagne oceanographique danoise de
1922 (Th. MORTENSEN, 1923) ont permis de recolter, pour la premiere fois, un materiel assez abondant de
crinoi'des pedoncules dans les eaux indonesiennes. Parmi ce materiel, le genre Saracrinus , autrefois ddcrit sous le
nom de Metacrinus, dtait particulierement bien represente. L’extreme variabilite de ces organismes avait conduit
les auteurs k une multiplication du nombre des especes. Des travaux recents (Roux, 1981 ; Bourseau & Roux,
1989 ; AMEZIANE-COMINARDI. 1991) nous conduisent a regrouper le materiel recolte lors du siecle dernier en trois
especes (tabl. 1).

campagnes du siecle dernier.
Une campagne rdeente (octobre 1991), KARUBAR, s'est deroulee au large des ties Kai, Tanimbar et Aru. Un
abondant materiel (165 specimens recoltes dont 158 mesures) de crinoi'des pedoncules a ete recueilli entre 210 et
430 m de profondeur (fig. 1). Cette faune comporte un seul genre de Pentacrine ( Saracrinus ), reparti en trois
espbees dont une est nouvelle pour la science. L’etude de cette faune est coni^ue comme directement
complementaire de celle des faunes du sud-ouest Pacifique et une comparaison sera dtablie entre les populations
de Saracrinus provenant des differentes regions du Pacifique occidental (fig. 2). Grace au grand nombre de
specimens recoltes, l’analyse quantitative des variations des principaux caracteres morphologiques du pedoncule
et de la couronne a pu etre realisee. Une telle demarche permet ainsi de cerner la variabilite intraspecifique qui

ETUDE SYSTEMATIQUE
Genre SARACRINUS A H. Clark, 1923
Rappelons rapidement les principals caracteristiques du genre Saracrinus, avant d'entreprendre une analyse
plus ddtaillee des differentes esp&ces : la premiere division des bras se situe, le plus frequemment, au niveau de la
quatriemc brachiale (I Br 4 ax), il s’ensuit que le nombre de primibrachiales (I Br) est toujours inferieur a 6 ; les
synostoses (articulations non fonctionnelles) des primibrachiales sont localises au niveau de la premiere et de
deuxieme primibrachiale (I Br 1+2).

PENTACRINES DE LA CAMPAGNE KARUBAR EN INDONESIE
633
Lors d'un precedent travail (AMEZIANE-COMINARDI. 1991), je signalais que Saracrinus angulatus etait une
espece polymorphe. De nombreuses especes telles que Saracrinus aculus , S. cingulatus, S. batheri, S. suluensis ,
especes typologiques, exprimaient cette variabilite, raison pour laquelle J.-P. Bourseau & M. ROUX (1989)
integraient tous ces taxons au sein de S. angulatus. Le faible nombre de specimens recoltes alors, restreignait notre
champ d’ investigation, l'apport de quelques specimens nouveaux m'avait permis de mettre en evidence les points
suivants :
- 1’ espece S. tuberosus correspond egalemcnt a un variant de S. angulatus ;
- la grande variabilite de S. angulatus s’exprime aussi bien au niveau des caracteres morphologiques externes
qu’au niveau des articulations ;
- enfin, bien que les diverses populations de S. angulatus du Pacifique occidental soient tres proches, elles se
differencient les unes par rapport aux autres par au moins une caracteristique. II semblerait qu’il existe une
Evolution des caracteres morphologiques en fonction de la localite geographiquc.
Les soixante et un specimens de S. angulatus prelev£s au large des ties Kai et Tanimbar vont permettre de
fournir un complement appreciable a la comprehension de cette espece.
DESCRIPTION DE LA MORPHOLOGIE EXTERNE. — Les specimens indonesiens de Saracrinus angulatus tendent a
etre robustes (fig. 12 A) et leurs principaux caracteres morphologiques se trouvent dans les Tableaux 2 a 6.

16gende que celle du tableau 2.
Le pedoncuie.
La section transversale du pedoncuie est tres etoilee ; quelquefois elle tend a prendre une forme pentagonale.
Les aretes se marquent fortement (fig. 12 E). Les pedoncules sont, en general, de forte taille. En effet, en partie
proximale, leur diametre varie de 3,6 a 9 mm (la moyenne se situant a 6,1 mm). Leur ornementation s exprime
sous differentes formes :
- carene fine, reguliere, continue et non tuberculde ;
- carene fine, reguliere, discontinue s'estompant au niveau des aretes ou elle est remplacee par une
protuberance isol6e ;

- enfin, apparition ponctuelle de quelques tubercules.
Le nombre d'internodales par noditaxis mature presente egalement une importante variability (tabl. 7). II est
compris entre 3 et 13 et se localise lc plus frequemment a 7. En dehors de la partie la plus proximate du
pedoncule, certains specimens presentent une forte heterometrie des internodales qui rdsulte souvent de
l'adjonction de nouvelles columnales. Les pores interarticulaires restent ouverts en partie distale sur une grande
portion du pedoncule. Ils pcuvent, occasionnellement, etre ouverts sur toute la longueur du pedoncule comme le
montrent deux specimens (n°15 et n°49). Le specimen n°59, quant a lui, se caracterise par des apparitions et
disparitions regulieres sur tout le pedoncule.

Tableau 7. — Variability de quelques caractfcres morphologiques chez Saracrinus angulatus (lies Kai et Tanimbar).
Le calice et la couronne de bras.
Les basales jointives montrent des formes differentes :
- basale aussi haute que large avec une apophyse distale pointue qui se marque fortement et qui recouvre les
premieres columnales ;
- basale piriforme, renflee et avec une apophyse distale peu marquee ;
- enfin, basale trapue possedant une apophyse peu marquee et emoussee, ainsi que deux apophyses externes
peu accentudes.
Le rapport de la largeur sur la hauteur des basales est en moyenne dgal a 1,2. Les radiales, quant a elles, sont
jointives, lisses et de forme rectangulaire. Le rapport de leur largeur sur leur hauteur est egal a 3. Les radiales du
specimen n° 52 presentent une apophyse inferieure.
De soixante it quatre-vingts bras constituent la couronne (fig. 12 B). Les brachiales sont le plus souvent lisses
mais parfois prennent un aspect rugueux. Le nombre de dichotomies atteint rarement cinq. Celui des brachiales
par serie augmente progressivement et regulierement des 1 Br aux V Br (tabl. 7). Les coefficients de variation sont
tres eleves a l'exception de celui des I Br. La largeur des brachiales decroTt depuis les 1 Br jusqu aux IV Br. Pour
les I Br, cette largeur est comprise entre 3,2 mm et 6,1 mm (moyenne = 5,1 mm) ; pour les 11 Br, elle se situe entre
2.7 mm et 5,1 mm (moyenne = 3,8 mm) et pour les III Br, elle est comprise entre 1,9 mm et 3,9 mm (moyenne =
2.8 mm). t
Les premieres pinnules sont composees en moyenne de 15 articles et ont une longueur d’environ 17.5 mm. Ces
pinnules sont massives et servent a proteger la masse viscerale. Les pinnules medianes (des II Br aux III Br)
possedent en moyenne 20 articles pour une longueur de 12,9 mm. Elies servent a vehiculer les parttcules
nutritives. La laille des pinnules est en relation avec celle des pedoncules ; plus l'individu est gros et plus les
pinnules tendent a etre importantes. C’est pourquoi, contrairement a certains auteurs (MacKnight, 1973 ; CHANG
& Liao, 1963), la taille des pinnules ne peut en aucun cas etre un critere discriminant differentes especes. Entin,
un S. angulatus (specimen n° 29) presente la particularity de posseder une pinnule bifide (fig. 12 C-D). En partie
distale, une des pieces de cette pinnule se comporte comme une axillaire et il y a dichotomic.
En introduction, je rappelle que les S. angulatus recoltes auparavant dans differentes regions du Pacifique
occidental se caracterisent par leur importante variabilite intraspecifique et leurs caracteres morphologiques qui
evoluent suivant le lieu geographique. Les S. angulatus preleves au large des ties Kai et Tanimbar prysentent

egalement une importante variabilite morphologique. II serait maintenant interessant d’effectuer une analyse
globaie en comparant, entre elles, ces populations de divers secteurs geographiques. Cette demarche permettrait de
verifier ainsi la validite des resultats obtenus lors de mes precedents travaux (Ameziane-Cominardi, 1991).

Ces populations sont done regroupees en quatre grands secteurs. LTndonesie est decoupee en deux sous-
secteurs : la mer de Timor et le secteur oriental de la mer de Banda (lies Kai et Tanimbar). Bien que
1 echantillonnage soil tr£s restreint pour la population de la mer de Timor (deux individus), je traiterai ce secteur
geographique independamment de celui, proche, de la mer de Banda. En effet, les deux specimens de la mer de

' so'1 a des orgamsmes qui appartiennent k une population dont les caracteres morphologiques se distinguent

La dermere hypothese se justifie par certaines observations faites sur les Saracrinus nobilis dans les eaux
indonesiennes (Amez.ane-Com.nardi, 1991). En effet, ces populations de 5. nobilis se caracterisent par des

En effet, dans le domaine intertropical, Australie et Indonesie (mer de Banda et de celle de Timor), les populations
PENTACRINES DE LA CAMPAGNE KARUBAR EN INDONESIE
637
de S. angulatus possedent un faible nombre d’intemodales (autour de 7). Quand nous nous eloignons de ces basses
latitudes pour monter vers le Nord, Philippines puis Japon, le nombre d’internodales croTt (8-9). II serait
interessant de voir revolution de ce caractere vers les hautes latitudes de l’hemisphere Sud, mais malheurcuscment
nous n’avons pas encore de populations de ces regions. Involution du nombre d’internodales par noditaxis
mature semble etre symetrique de part et d’autre de l’Equateur. En outre, cette evolution latitudinale globale peut
etre masquee partiellement par une variability locale plus ou moins importante.

latitude chez Saracrinus angulatus.
In : mode du nombre d’internodales par noditaxis mature ; N : nombre d’individus ; • : mode pour le nombre
d’intemodales. la grosseur du point represente la taille de la population.
La partie proximale du pedoncule se caracterise chez les Pentacrines par la presence de pores interarticulaires.
Cette zone, qui caractdrise la zone de forte croissance des pedoncules, est toujours mieux developpee chez des
individus adultes que sur des formes juveniles. L'etude du parametre “zone d extension des pores interarticulaires
dans la partie proximale du pedoncule” (fig. 4) montre que :
- cette zone d’extension des pores interarticulaires peut etre tr£s developpee (faune de Banda) ;
- au contraire, elle peut etre restreinte (faune japonaise et Philippine) ;
- enfin, le reste de la faune se repartit entre ces deux extremites.
L’analysc de ce parametre indique que la faune du Japon et celle des Philippines presentent pour ce caractere
une tendance pedomorphique.
La couronne de bras.
L’organisation de la couronne de bras varie suivant les secteurs (fig. 5). Les taunes philippine et japonaise
presentent une organisation statistiquement plus reguliere que montre une variability globale plus restreinte. En
effet, le nombre d’ossicules par serie brachiale augmente regulierement et progressivement. Les faunes de Timor,
de la mer de Banda et d'Australie tendent a posseder moins d'ossicules par tronc brachial.

La repartition selon les secteurs geographiques de S. angulatus montre des differences importantes au niveau
des coefficients de variation. Ainsi, les faunes du Japon, des Philippines et de la mer de Banda, presentent la

Philippines. En revanche celle de Timor se caracterise par une importante variability pour toutes les sdries
brachiales alors que celle d'Australie a les plus forts coefficients de variation pour les deux premieres series
brachiales et les deux plus faibles pour les troisieme et quatrieme.
Bien qu'irreguliere, la position des dichotomies n'est pas le fait du hasard (Ameziane-Cominardi, 1991 ;
BOURSEAU et al. , 1991). Celie-ci pourrait etre l'expression d'une organisation plus complexe qui serait
significative de l'optimalisation de la fonction "filtration". Ainsi, lorsque la repartition des axillaires dcs deux
premiers troncs est reguliere, celle des derniers troncs est irreguliere. En revanche, lorsque la repartition des
premiers troncs brachiaux est irreguliere, celle des derniers troncs est reguliere. Ainsi, l'importante variability de la
repartition des I Br ax et II Br ax de la faune australienne se trouve correlee a une faible variability des III Br ax et
IV Br ax. Le decalage des dichotomies pennet une meilleure repartition des pinnules au sein du cone forme par la
couronne deployee.
Pour la faune des Philippines, alors que le diametre du pedoncule augmente en fonction de la profondeur, le
nombre de bras decrott (tabl. 10) ; le maximum de bras se situant vers 210 m. En revanche, a profondeur egale et a
diametre pedonculaire equivalent, le nombre de bras de la faune japonaise est plus faible. A profondeur similaire
et diametre du pedoncule egal, les faunes de la mcr de Banda et d'Australie possedent un nombre de bras plus
eleve que celui de la faune des Philippines. II semble que le creneau bathymetrique le plus propice au
developpement des S. angulatus change suivant le lieu geographique en fonction des parametres de
l’environnement, notamment des courants. Nous constatons que le nombre de bras de la couronne decroTt du sud
vers le nord.

Tableau 10. Nombre de bras chez Saracrinus angulatus en fonction de la profondeur du milieu et de la repartition
gyographique.
Caracteres des articulations. — Les zones petaloides des symplexies (fig. 12 H-I) du pedoncule se
caractynsent par des areolas lanceolees (en moyenne deux fois plus longues que larges) a trbs fortement lanceolees
(environ trois fois plus longues que larges). Certains specimens presentent, au sein du reseau de leur areola, de
grosses mailles. Le crenularium interne s'individualise bien. Le nombre de cryneaux varie de 12 a 18 (tabl. 1 1). De
plus, ce nombre de creneaux diminue avec la reduction du diametre du pedoncule. La forme et la largeur des
zones mterpetaloides varient egalement (tabl. 1 1). Le perilumen de tous les specimens se marque fortement. Le
canal axial est toujours circulaire.
Les zones petaloides des synostoses du pedoncule (fig. 12 F-G) se caracterisent par des areolas lanceolees
environ deux tois plus longues que larges) a ires fortement lanceolees (en moyenne trois fois plus longues que
larges). L ensemble du crenularium est bien individualise. Le nombre de creneaux fluctue entre 12 et 15. Le reseau
secondaire contenu dans le canal axial est regulier et de densite plus ou moins lache. La forme du lumen, quant a
elle, est pentalobee de fa?on plus ou moins reguliere (tabl. 11). Les synostoses de la partie distale s'ankylosent
souvent. J
Conclusion. - La grande variability de 5. angulatus s'exprime tres fortement au niveau des caracteres
morphologiques externes et plus faiblement au niveau des articulations. Bien que tres proches, les diverses
populations presentent toutes des differences les unes par rapport aux autres (fig. 6).
‘ aune d Australl®el celle de la mer de Timor presentent les plus forts pourcentages de variation cumulee
alors que la faune des Philippines possede le plus faible. II est etabl. que les specimens considers comme adultes

interarticulaires plus importante, un nombre d'internodales par noditaxis mature plus pent, un nombre de bras plus
eleve et un nombre d'ossicules par serie brachiale moindre. Pour l’ensemble de ces caracteres. les faunes du Japon
et des Philippines ont des individus qui correspondent a des formes plus juvemles. Ces deux populations montrent
done une tendance pedomorphique pour la majority des caracteres morphologiques. Ces tendances evolut.ves a
grande variabilite intraspecif.que pourraient traduire une adaptation phenotyp.que aux cond.tions ecologies.

Cette espece, largement etudiee (Am£ziane-Cominardi. 1991 ; Bourseau et al., 1991) possede une large aire
de repartition comprise entre le Japon et la Nouvelle-Zelande. S. nobilis presente de nombreuses affinites
morphologiques avec S. superbus et les S. varians recoltes dans les milieux profonds. Lors de precedents travaux
(AMEZIANE-COMINARDI. 1991), je signalais que ces trois taxons constituaient un gradient morphologique qui se
singularisait par sa vaste repartition geographique. Leur distribution met en evidence un double relais. Le premier
est un relais ecophenotypique geographique et il affecte seulement les variants de S. nobilis. En effet,.le nombre
d'internodales par noditaxis mature de ces derniers augmente suivant la ligne Sumatra-Timor-Mer de Banda-
Nouvelle-Caledonie. Le second relais ecophenotypique est bathymetrique. Ainsi, S. superbus domine vers 200 m,
S. nobilis vers 300-500 m et S. varians semble infeode aux milieux profonds (AMEZIANE-COMINARDI. 1991).
DESCRIPTION de la morphologie EXTERNE. — La faune de crinoi'des pedoncules recoltes lors de la mission
Karubar livre une quarantaine de Saracrinus nobilis dont la localisation geographique est precisee dans la liste
des stations. L'ensemble des caracteres morphologiques des individus est donne dans les tableaux 12 & 15.

Tableau 1 5. — Principaux caractfcres morphologiques du pedoncule et de la couronne chez Saracrinus nobilis (suile) Meme
legcnde que celle du tableau 2.
Les indi vidus sont de grande taille (fig. 13 A). En effet Ieur diametre varie, en partie proximale, entre 4,8 et
8 2 mm (moyenne - 6,4 mm). La section transversale du pedoncule est toujours etoilee dans sa partie proximale
alors quelle devient circulate ou subpentagonale en partie distale. Le pedoncule est tres souvent lisse (fig. 13 C)
mais quelquefois presente des tubercules plus ou moins marques. Le nombre d'internodales par noditaxis mature
fiuctue entre 8 et 15 et se trouve le plus souvent a 13 (tabl. 16). La longueur de la zone d'extension des pores
interarticulaires est importante (tabl. 16). Les premiers articles des cirres sont arrondis et peu epais puis
deviennent trfes rapidement subrectangulaires et legerement arrondis sous la face inferieure de 1'article formant
atnst une petite apophyse.

Les radiales de forme rectangulaire et jointives, sont en moyenne trois fois plus larges que hautes (rapport de la
largeur sur la hauteur = 3,1). La largeur des radiales tend a augmenter avec l'accroissement du diametre pedoncu-
laire. De meme, quoique moins marquee, cette tendance s'observe pour la hauteur et la largeur des basales. En
revanche, pour l'bventail de valeurs actuellement disponibles, la hauteur des radiales n’est pas fortement liee a la
taille du pedoncule. Le specimen n°7 se caracterise par des radiales de petite taille, notamment au niveau de leur
largeur. Cette particularite peut resulter d'un probleme de regeneration. Le specimen n°l presente, quant a lui, des
radiales exceptionnellement bien developpees.

Diametre du pcdoncule (en mm)
Fig. 7. — Dimensions du calice (hauteur et largeur des basales et des radiales) en fonction du diametre maximum du pedoncule
pour Saracrinus nobilis (iles Am. Kai et Tanimbar).
H : hauteur ; 1 : largeur.
Le nombre maximum de bras est compris entre 60 et 120, atteignant rarement six dichotomies (fig. 13 B). Des
verrues ornent les brachiales de quelques individus leur donnant ainsi un aspect rugueux. Le nombre d ossicules
contenus dans chaque serie brachiale augmente regulierement et progressivement depuis les I Br jusqu'au VI Br.
Les pinnules proximales se composent en moyenne de 16 articles pour une longueur de 18,6 mm. Leurs articles
proximaux sont massifs et trapezoidaux, alors que les articles plus distaux sont fins et rectangulaires. Le specimen
n° 24 se particularise par des pinnules proximales anormalement longues, qui peuvent atteindre voire depasser 31
mm de longueur. Les pinnules medianes, situees sur les II Br et III Br, ont en moyenne 21 articles pour une
longueur de 15,4 mm.
Les formes les plus robustes, dont le diametre pedonculaire est superieur a 6,5 mm, possedent les caracteris-
tiques suivantes : leur nombre d'internodales par noditaxis mature se situant tres frequemment a 13, une section
transversale du pedoncule arrondie, un nombre de bras important (souvent superieur a 80). Ces principaux criteres
ont permis a Carpenter (1884) de decrire une nouvelle espece Saracrinus superbus. Nous ne pouvons, pour la
faune indonesienne, discriminer les 5. nobilis des S. superbus. ce qui corrobore les hypotheses faites auparavant
(DODERLEIN, 1907 ; Bourseau & Roux, 1989 ; BOURSEAU et al.. 1991). S. superbus doit done etre mis en syno-
nymie avec S. nobilis. S. superbus representerait un morphotype stable, atteignant un stade “senile", de S. nobilis.
Ce morphotype stable s’epanouirait dans les milieux peu profonds et abrites, alors que S. superbus plus poly-
morphe (pole opportuniste) relaie le premier dans un creneau bathymetrique plus profond (300-500 m).
CARACTERES DES ARTICULATIONS. — Les zones petaloides des symplexies (fig. 13 F-G) du pedoncule peuvent
etre de forme lanceolee a bout triangulaire ou piriforme. De grosses mailles sont presentes au sein du reseau des
areolas de certains specimens. Les aires interpetalo'fdes sont en moyenne 1,2 fois moins larges que les zones

petaloi'des et s'evasent vers l'exterieur. Le crenularium interne est peu developpe. Le nombre de creneaux est
compris entre 12 et 15 (mode a 14). Le perilumen se marque fortement autour du canal axial subcirculaire.
Les synostoses possedent des areolas lanceolees et sont en moyenne 1,6 fois plus larges que les zones
interpdtaloides (fig. 13 D-E). Le nombre de creneaux est compris entre 9 et 10 (mode a 10). Le reseau du canal
axial est dense et irrdgulier. Le lumen, quant a lui, presente une ebauche de lobes.
Rapports et differences. — Les S. nobilis de Karubar entrent dans le champ de variation des 5. nobilis du
reste de la faune du Pacifique sud-ouest (Ameziane-Cominardi, 1991) et presentent les particularites suivantes :
- de faibles coefficients de variability pour les caracteres morphologiques externes tels que le nombre d'inter-
nodales par noditaxis mature et la position de 1'axillaire de la premiere serie brachiale (I Br ax) ;
- une zone d'extension des pores interarticulaires plus etendue ;
- un nombre de brachiales plus eleve pour les quatrieme et cinquieme series brachiales. Ces deux series, pour
le reste de la faune du Sud-Ouest Pacifique, sont constituees d'une quinzaine de pieces ;
- a diametre pedonculaire egal et a profondeur equivalente, un nombre de bras beaucoup plus important.
La faune indonesienne (lies Aru, Kai et Tanimbar) presente d’une part une plus grande stability morphologique
et possede d'autre part des caracteres beaucoup plus matures que le reste de la faune du Pacifique sud-ouest. Cette
laune indonesienne par rapport au reste de la faune se compose de formes que nous pouvons qualifier de "super
adultes" (Ameziane-Cominardi, 1991). Ces caracteristiques pourraient resulterde conditions environnementales,
telles que l'hydrodynamisme, l'aspect du substrat et les apports trophiques, qui seraient plus stables pour les sites’
indonesiens.

Etymologie. — L'espece est dediee au Dr K. Moosa, chef de mission indonesien de la campagne Karubar.
Diagnose de L'ESPECE. — Saracrinus de taille tres moyenne et de morphologic variable. Pedoncule de section
pentagonale et, le plus souvent, depourvu d’ornementation. La longueur du pedoncule est petite par rapport a celle
de la couronne de bras. Le nombre d'internodales par noditaxis mature est generalement de 5 ou 6. Les cirres sont
pctits, freles et trois a quatre fois plus longs que les internodes. La surface externe des bras est lisse. Les brachiales
preYinent souvent un aspect globuleux. L'organisation de la couronne est la suivante : 3 a 8 I Br (mode a 4), 4 a 13
II Br (mode a 9), 7 a 31 III Br (mode a 13). Les articulations du pedoncule et des bras sont differentes de celles de
5. angulatus et de S. varians (les plus profonds), especes avec lesquelles S. moosai presente le plus d'affinites.
description dela morphologie externe. - L’holotype (specimen n°45) est un specimen de taille plutot
moyenne (fig. 14 A). La longueur du pedoncule est de 1 1 cm pour 26 noditaxis ; son diametre en partie proximale
est de 5 mm et sa section transversale est pentagonale (fig. 14 E). Le pedoncule est de petite taille par rapport a la
couronne de bras. Le pedoncule tend a etre lisse et presente localement une tres faible omementation qui se traduit
par un leger renflement du centre de l'ossicule. Les columnales se caracterisent par une heterometrie. L'epaisseur
des nodales les plus grosses atteint 1,2 mm et celle des internodales 1,0 mm. La hauteur des noditaxis ne depasse
p 7,2 mm. Les pores interarticulaires s'observent jusqu'au douzieme internode. Le nombre total d'internodales

Les basales, d aspect trapezoidal, sont jointives. Les radialcs, joinlives ct de forme rectangulaire, sont deux fois
plus larges que hautes. Le noinbre de bras est de quarante (fig. 14 B). La hauteur de la couronne est de 121 mm.
Son organisation est la suivante : I Br 1+2 (5 cas), 4+5 (1 cas), 4 ax (4 cas), 5 ax (1 cas) ; II Br 3+4 (9 cas), 1+2
(1 cas). 5+6 (1 cas), 7 ax (2 cas), 8 ax (1 cas), 9 ax (7 cas) ; III Br 3+4 (19 cas), 4+5 (1 cas), 1 1 ax (6 cas), 13 ax
(6 cas), 14 ax (1 cas), 15 ax (3 cas), 16 ax (4 cas). Deux troncs brachiaux presentent une regeneration ; l'une, au
stade final, affecte la septieme secondibrachiale et l'autre se localise au niveau de ia quatri&me seric brachiale. Les
premieres pinnules (PI) presentent une surface externe qui tend parfois a etre rugueuse et une section
subrectangulaire. Leur longueur atteint 17,1 mm pour environ 15 articles. A partir des II Br, les pinnules
deviennent plus petiles (12,2 mm pour 16 articles) et leur surface externe perd I'aspect rugueux. L'extremite des
bras est depourvue de pinnule fonctionnelle sur environ 26 mm. Les brachiales les plus distales portent
effectivement des pinnules rudimentaires, constitutes de deux ou trois ossicules.

Les Tableaux 17 a 22 regroupent les caracteres morphologiques externes de tous les specimens, y compris
ceux de la sene-type. Pour lensemble de ces individus, la section transversale du pedoncule est pentagonale
parfois une tendance arrondie se dtveloppe chez quelques individus. La section transversale des nodales peut
tendre vers une fomie dtoilee. La plupart des specimens a un pedoncule plutot gracile par rapport a leur couronne
de bras. Les diametres atteignent cxceptionnellcment 6,0 mm et varient en partie proximale entre 2,3 mm et 6 0

Les basales sont soit jointives (79 % des cas), soil disjointes (21 % des cas). Elies peuvent parfois posseder une
apophyse distale. Le rapport de leur largeur sur leur hauteur est egal a 1,46. Les radiales, jointives, sont en
moyenne deux fois et demie plus larges que hautes, et ont ainsi un aspect rectangulaire. Les infrabasales sont
egalement presentes (fig. 14 C-D) et se trouvent a l'interieur du cercle de basales. La presence des infrabasales,
decrite pour d’autres espkces (Ameziane-Cominardi et ai, 1991 ; Clark, 1908b ; Doderlein, 1907), semble
etre une caracteristique des Metacrininae.

Fig 9. — Morphologie du systeme entoneural (systeme nerveux aboral) dans le calice chez Saracrinus moosai sp. nov. (ties
Kai, Indonesie).
A : projection horizontal ; B : vue de profil.
L'analyse detaillee des pieces de la coupe dorsale permet de transcrire le parcours, dans le calice, du systeme
nerveux entoneural (fig. 9). De l’organe cloisonnd, partent cinq troncs nerveux qui se divisent chacun au niveau
des infrabasales. Deux branches nerveuses pen£trent done dans chaque basale, dies ont pour origine deux
infrabasales differentes. Ces branches sont reliees entre elles, vers le tiers posterieur (cote pedoncule), par un
troisieme cordon nerveux. Ce dernier ne relie entre elles que les branches nerveuses appartenant a la nieme basale,
e'est pourquoi ce cordon nerveux est discontinu. Dans chacune des cinq radiales se trouvent deux ramifications
qui proviennent de basales differentes. Au sommet de la partie anterieure (cote couronne de bras), les deux
branches se soudent dans la radiale et un cordon nerveux circulaire apparait egalement a ce niveau, ce qui permet
une meilleure cohesion du cercle de radiales. Par consequent, une seule branche nerveuse sort de la partie
anterieure de la radiale et entre dans la premiere brachiale. La position des cordons nerveux se revele semblable a
celle de Neocrinus decorus et Metacrinus rotundus (A.H. Clark, 1908c).

La couronne brachiale est frequemment constitute d'une quarantaine de bras. Les dichotomies, au niveau de la
quatrieme strie brachiale, sont rares (tab!. 23) et sont exceptionnelles pour la cinquieme serie brachiale (I cas). Le
nombre d ossicules par serie brachiale augmente regulierement et constamment depuis les I Br jusqu'au IV Br (fig.
10). Pour les II Br, un second mode s’exprime au niveau de la septieme brachiale (fig. 10). De meme, pour les III
Br, il existe un second mode au niveau de la onzieme el de la treizieme brachiale et pour IV Br, ce second mode se
trouve aux treizieme, quinzieme et dix-ncuvieme brachiales. La repartition du nombre d’ossicules par serie
brachiale evolue depuis les I Br ou il existe un seul mode (82 % des cas), jusqu’au IV Br ou s’exprime un mode
majcur (24 % des cas) et plusieurs modes secondaires. Ces modes se localisent, a I’exception de la premiere serie
brachiale, toujours au niveau d’un nombre impair de pieces. Les brachiales ont souvent un aspect globuleux. La
largeur des brachiales varie entre 2,9 mm et 5,6 mm pour les I Br (moyenne = 4,7 mm), entre 1,9 mm et 4,1 mm
pour les II Br (moyenne = 3,6 mm) et entre 1,4 mm et 3,7 mm pour les III Br (moyenne = 2,7 mm). La largeur
des ossicules, pour chaque serie, a ete mesuree generalement sur la deuxieme brachiale. La largeur des brachiales
decro.t done regulierement depuis les I Br jusqu’au IV Br et elle est en relation avec la taille du diametre
pedonculaire, exception faite des interferences dues a la regeneration des ossicules. Les premieres pinnules,
massives, sont composees en moyenne de 14 articles et ont une longueur d'environ 14,5 mm. Les pinnules
medianes (des II Br aux III Br) possedent en moyenne 17 articles pour une longueur de 10,7 mm.

s'6vasant vers l'exterieur de la piece (en moyenne 1,5 fois moins larges que la zone petaloi'de). Le perilumen
s'exprime tres fortement. Le canal axial est de forme circulaire.
Les zones petaloi'des des synostoses du pedoncule sont egalement lanceolees (fig. 15 B-C). Ces zones sont
egalement soit ouvertes vers l'exterieur, soit fermees. Le nombre de creneaux varie entre 8 et 10 (mode a 10). Les
zones interpetalo'ides sont bien differences (en moyenne 1,75 fois moins large que la zone petaloTde). Ces zones
interpetaloi'des sont beaucoup plus larges au niveau des synostoses distales. Le reseau secondaire qui remplit le
canal axial est de forme pentagonale, lache et regulier. Le lumen secondaire est irregulier et pentalobe.
Les synarthries des bras ont une Crete fulcrale qui est nettement oblique et bien en relief (fig. 15 E, G). Le
sillon interne, qui separe les aires musculaires, est etroit. La zone ligamentaire externe est non seulement bien
developpee mais est egalement fortement evidee. Les aires ligamentaires internes presentent une limite franche
avec les aires musculaires. Ces dernieres sont bien developpees et leurs zones de croissance sont tres apparentes.
L'insertion pinnulaire provoque une dissymetrie des aires musculaires. Une evolution de la microstructure des
synarthries existe depuis les brachiales proximales jusqu'aux brachiales distales (fig. 15 E, G, H, J). En effet, le
perilumen qui entoure le canal axial est bien individualist et a une forme trapezoidale pour les ossicules
proximaux, alors qu’il est pratiquement inexistant pour les ossicules distaux. Les zones musculaires deviennent de
plus en plus restreintes et sont pratiquement inexistantes en partie distale. L'evidement de l'aire ligamentaire
externe est de plus en plus faible, de meme que la crete fulcrale se difference de moins en moins, au fur et a
mesure que les brachiales apparaissent en position distale.
Les synostoses des bras sont generalement planes (fig. 15 D, I). Le sillon median est bien marque. Les
synostoses proximales (fig. 15 D) presentent, des la partie mediane de l'articulation, des epaississements
concentriques de reseau syzygial. Ces epaississements sont absents des synostoses distales (tig. 15 I).
Pour les deux types d'articulation, le canal axial dvolue depuis des formes rectangulaires pour des brachiales
proximales jusqu'a des formes circulaires en partie distale.
Les premiers ossicules des pinnules proximales ou mddianes possfedent des synarthries qui sont beaucoup plus
evoluees que celles des brachiales les plus distales (fig. 15 K, M). Leurs cretes fulcrales, bien que peu
differenciees au niveau microstructure, sont nettement individualists. De meme, les aires musculaires sont
visibles. En revanche, les ossicules plus distaux des pinnules proximales ou medianes sont tres peu differences
(fig. 15 L).
RAPPORTS et DIFFERENCES. — Saracrinus moosai est associe avec S. nobilis et S. angulatus. S. moosai
sp. nov. est tres different de S. nobilis , alors que certains specimens ont un aspect general qui presente parfois
quelques analogies avec S. angulatus. Cependant l'etude detaillee des caracteres morphologiques permet de
separer les deux especes. En effet, meme si quelques noditaxis matures du pedoncule de certains S. moosai
sp. nov. se composent parfois de 7 columnales, la majorite d'entre eux possedent 5 S 6 ossicules. De plus, la zone
d’extension des pores interarticulaires est beaucoup plus restreinte chez S. moosai sp. nov. En revanche,
difference S. moosai sp. nov. de 5. angulatus seulement avec la couronne de bras se revele difficile. Toutefois, il
semble que S. moosai sp. nov. possfede plus d'ossicules au niveau de la deuxieme serie brachiale. Au niveau des
articulations du pedoncule, S. moosai sp. nov. presente par rapport a S. angulatus les differences suivantes : des
zones petaloi'des des symplexies et des synostoses beaucoup moins lanceolees ; un nombre de creneaux plus
faible ; un crenularium interne peu developpe et un perilumen moins large. Les principales differences au niveau
de l'articulation des bras se situent essentiellement au niveau de l'obliquite de la crete fulcrale (plus forte chez 5.
moosai) et la presence, chez S. angulatus, d'apophyses calcitiques sur les bords internes de l'aire ligamentaire.
S. moosai sp. nov. tend egalement a presenter de tres fortes affinites avec trois des cinq S. various decrits par
L. DODERLEIN (1907). Ces individus ont ete recoltes a la station 253 de l'expedition de la "Siboga". Cette station
se trouve a proximite de la station CP 05 de Karubar et a une profondeur similaire. Les specimens decrits par L.
DODERLEIN presentent non seulement la meme allure generate mais egalement des caracteristiques
morphologiques identiques. Ce sont done bien des 5. moosai. Le nombre limite de S. various et la faible
connaissance sur l'importante variabilite inherente a chaque espece a masque cette nouvelle espece. Les deux
autres S. various, preleves entre 500 et 600 m. sont des morphotypes profonds de S. nobilis (AMEZIANE-
COMINARDI, 1991).

CAS DE REGENERATIONS
Les crinoi'des pedoncules ont une grande capacity k se regenerer (Bourseau et al., 1991 ; OJI. 1986) et peu-
vent le faire plusieurs fois au cours de leur existence. Une taille plus petite et une couleur differente, souvent plus
claire, indiquent que 1 individu est en cours de regeneration. La regeneration traduit un instant t qui ici est le
moment du prelevement. En effet, un specimen peut s'etre deja regenere plusieurs fois et ne porter aucune trace
significative de cette regeneration lors de sa recolte, car il se trouve dans une phase de “non-regeneration”. La fre¬
quence de regeneration sur I'ensemble d’une population recoltee dans une meme station refletera les perturbations
subies par les mdividus. Theoriquement, toutes les parties de l’organisme presentent la possibility de se regenerer
Ma.s la presence des basales (Ameziane-Cominardi, 1991 ; Amemiya & Oji. 1992) et de la partie proximale du
pedoncule se revele indispensable pour que la regeneration s’effectue. En effet, le centre nerveux aboral contenu
dans ces elements est necessaire pour que le processus se declenche. Les results d'experimentation (Amemiya &
OJI. 1992) montrent egalement qu’une resorption de la partie proximale du pedoncule se manifeste lorsque
I'ensemble de la couronne de bras est en cours de regeneration. Cette particularity a ete observee chez un
Metacrinus levii (Bourseau et al., 1991), un M. wyvillei et un M. serratus (BOURSEAU & ROUX, 1989).
Le pedoncule. L’observation du pedoncule en cours de regeneration est rare. Aucun des individus recoltes
lors de la mission Karubar ne presente de regeneration visible du pedoncule.
Lecalice. — Un seul specimen ( Saracrinus moosai, specimen n°l) montre une anomalie au niveau du calice
En effet cet indiv.du possede six radiales ; l'une d'entre-elles etant plus petite et surdlevee par rapport aux autres.
Chacune de ces six radiales porte un tronc brachial. Cette anomalie peut resulter soil d'un probleme lors d’une
regeneration, soit d'un defaut de naissance.
La couronne de bras. — La regeneration des bras, quant il elle, est frequente et les cassures s'effectuent gdnd-
ralement au niveau des synostoses. Une aberration particuliere, due certainement a un probleme de regeneration
est observe pour la premiere fois chez un 5. angulatus (specimen n°2). Au niveau de la quatrieme primibrachiale
(1 Br 4) ou normalement se situe la division brachiale, se trouve une axillaire avortee (fig. 11). En effet, cette
piece a failure generale dune axillaire par sa forme losangique, accentuee par un bee central. A fendroit’ou se
localise habituellement la pinnule, apparaissent deux brachiales singulieres : la premiere (1 Br 5), tres petite se
niche dans le creux de la I Br 4 lui conferant ainsi une vocation d'axillaire ; la seconde (I Br 6) recouvre non
seulement la I Br 5 ma.s egalement une partie de la I Br 4. De cette situation, il resulte une dissymetrie de la I Br 6
qu. est bien dSveloppee du cote ou se trouve I Br 5, mais qui est tres fine sur le cote oppose. La fonc.ion de cette
piece serait de comger 1 anomalie induite par I Br 4. Pour ce tronc brachial, faxillaire se localise, en fait, au niveau
de la huitieme brachiale (I Br 8 ax).

Les frequences de regenerations s’obticnnent a partir du nombre total de regenerations obscrvees sur une
meme serie brachiale compare au nombre total de troncs brachiaux de tous les individus (regeneres ou non) pour
cette meme serie brachiale. Sur l’ensemble des bras, S. nobilis presente les plus forts pourcentages de
regenerations et S. angulatus les plus faibles (tabl. 24). Pour les trois especes, ce sont au niveau des II Br et III Br
que s’observent le plus grand nombre de regenerations, alors qu'elles sont les plus rares au niveau des I Br et V
Br. Toutes les frequences de tres jeunes regenerations augmentent depuis les II Br jusqu’au V Br, k l’exceplion
des III Br de S. moosai sp. nov. II semble que les parlies distales, plus fragiles, se r6g6nerent plus souvent. Si nous
comparons ces donndes avec celles obtenues dans le SW Pacifique (AMEZIANE-COMINARDI, 1991), nous
constatons que les S. angulatus indonesiens (lies Kai et Tanimbar) se caracterisent par un taux de regeneration
plus faible que celui observe chez ceux recoltes dans le reste du SW Pacifique. Les S. nobilis d'Indonesie (lies
Aru, Kai et Tanimbar), quant a eux, montrent un taux de regeneration plus important pour les trois premieres
series brachiales que celui obtenu chez les individus recoltes dans le reste du SW Pacifique. Les S. nobilis
indondsiens se caracterisent egalement par une plus forte variabilite de leurs caracteres morphologiques.

La relation qui existe entre les fortes frequences de regeneration et les forts coefficients de variation chez de
nombreuses especes (BOURSEAU et al., 1991) se verifie de nouveau. Les mysostomes ont ete invoquds, de meme
que la predation et faction des courants (A.H. CLARK, 1921 ; CONAN et al., 1981 ; OJI, 1986), pour expliquer la
cassure des bras. Aucun mysostome n'a ete trouve chez S. moosai. En revanche, chez certains specimens de
5. angulatus et S. nobilis, un certain nombre de mysostomes sont presents. Ces organismes affectent aussi bien les
brachiales que les pinnules. Un individu peut etre infeste par de tres nombreux mysostomes ; par exemple,
quatorze individus parasitent le S. nobilis n°19 et douze parasitent le n°21.
CONCLUSIONS
L’etude du materiel recueilli par la campagne Karubar confirme qu'il existe une grande variabilite
intraspecifique chez les Metacrininae et que de nombreuses especes sont, en fait, des ecophenotypes qui sont
susceptibles de traduire les variations du milieu environnant. Sur les huit especes de Metacrininae recoltees aux
abords des lies Kai lors de precedentes campagnes ("Challenger", "Siboga", expedition danoise), trois especes

seulement sont indiscutablement presentes dans cette region. Ainsi, Saracrinus acutus, S. cingulatus, S. tuberosus
deviennent synonymes de S. angulatus, de meme que S. superbus , S. murrayi, S. varians (certains specimens) sont
synonymes de S. nobilis. Les S. varians, dccrits par L. Doderlein, ont ete mal identifies et correspondent a des
5. moosai sp. nov.
Lors des diverses campagnes, passees ou recentes, les specimens preleves dans une meme station appar-
tiennent souvent a des especes et a des genres differcnts. Quelquefois, S. nobilis et 5. angulatus sont associes dans
un meme site, mais la encore la faune de Karubar se singularise par la presence simultanee de trois especes
appartenant au meme genre.
La faune recoltee lors de la campagne Karubar se caracterise par des populations homogenes depourvues de
juveniles. En effet, les Saracrinus nobilis et angulatus, par rapport au reste de la faune SW Pacifique, ont de fortes
taiHes. De meme, S. moosai, espece plus gracile que les deux prccedentes, semble se situer a un pole maximal de
croissance. Plusieurs hypotheses peuvent etre envisagees pour tenter d'expliquer cette situation :
- il peut exister un probleme au niveau de l'echantillonnage. Les techniques de prelevements utilisees sont les
memes que celles employees lors des campagnes effectuees au large de la Nouvelle-Caledonie, region ou de
nombreux juveniles ont etc recoltes alors que le nombre total d'individus preleves est moindre que celui de la
campagne Karubar. Cette premiere hypothese semble done peu vraisemblablc ;
les larves des Saracrinus des Ties Kai se deplacent, de fa^on active ou passive (action des courants), et
s'installent ailleurs ;
- enfin, ces populations ont des vitesses de renouvellemeni faunistique lentes car leur environnement est stable.
Lors des campagnes effectuees auparavant au large des Ties Kai, Democrinus weberi et un Rhizocrinus
(stations 56 et 58 de l’expedition danoise, MORTENSEN, 1923) ont ete preleves en meme temps que des
Saracrinus. GlSLEN (1925) decrit un Democrinus globularis et un Porphyrocrinus verrucosus (station 56 de la
"Siboga "). Des prelevements ont ete faits aux memes endroits et a dcs profondeurs similaires, mais
malheureusement aucune de ces especes n'a ete recoltee.
De nombreuses autres especes sont potentiellement presentes dans ces eaux. Au sein des Pentacrinidae, les
diverses recoltes passees ont permis d' identifier Metacrinus serratus (mer de Sulu), M . wyvillei (Celebes),
M. costatus (Celebes), Diplocrinus sibogae (mer de Timor), Hypalocrinus naresianus (Celebes). L’absence de
Metacrinus est surprenante car ce genre se trouve tres frequemmcnl et plus regulierement que Saracrinus dans
tout le SW Pacifique. Enfin, parmi les Bathycrinus, B. minimus (Celebes), B. nodipes (Celebes et Banda) et
B-Poculum (Banda) ont ete preleves lors du passage de la "Siboga". Parmi la quinzaine de stations de Karubar
effectuees a des profondeurs ou se developpent generalement de telles especes, aucune n’a fourni de crinoides
pedonculcs. Deux hypotheses peuvent expliquer I ’absence de ces organismes : soit ces formes sont effectivement
presentes aux abords des lies Kai et n’ont pas ete recoltes pour des raisons diverses telles que : zones de
developpement tres restreintes, deplacement des organismes, probleme d’echantillonnage ; soit alors ces especes
ne vi vent pas dans ce secteur. Nous constatons que la faune des diverses mers qui separent les lies (Timor,
Celebes, Banda..) differe suivant les secteurs (especes rencontrees qu’a un seul endroit ; cf. Diplocrinus sibogae)
et de plus elle presente des variations morphologiques importantes pour des especes deja connues (cf. Saracrinus
nobilis et S. angulatus). Ainsi, les crinoides pedoncules pourraient etre caracteristiques de chacune de ces regions,
mais en 1 etat actuel de nos connaissances ceci reste une simple supposition.

Ever since the explorations of the Danish Expedition to the Kei Islands, led by the famous zoologist
Th. MORTENSEN in 1922, the eastern seas of Indonesia have been renowned as a hotspot of marine biodiversity.
In 1991, the French-Indonesian KARUBAR cruise took place on board R.V. Banina Jaya 1 in the Banda and
Arafura Seas, off the Kai and Tanimbar Islands (Eastern Indonesia). The expedition, which had a dual zoological
and fisheries goal, collected a rich material of deep-sea benthos between 200 and 1200 m. Scattered faunistic
results have already been published elsewhere, but the present volume is the first consolidated report, consisting
of a narrative and 13 contributed articles on the systematics and biogeography of Scleractinia (1 paper), Mollusca
(5 papers), Crustacea Decapoda (6 papers) and Crinoidea (1 paper). Among the more remarkable results is
a review of the highly diverse azooxanthellate coral fauna from the Philippines and Indonesia, and a description of
a major new hermit crab assemblage.
Altogether the contributions report new data on over 400 species of invertebrates, of which 97 species and
1 1 genera are described as new. The volume is richly illustrated with numerous photographic plates, line
drawings and 2 colour plates, representing living animals. Because of the key biogeographical position of
Indonesia, the results presented in this volume bear relevance to a vast region in the tropical Indian and Pacific
Oceans.
